自動車産業や航空宇宙産業では，車体や機体の軽量化のために有機材料や炭素
繊維強化樹脂（CFRP）の利用が検討されており，金属材料と有機材料との接合プロセスの開発が強く求められており，それら非金属材料の接合メカニズムに関する学術的基礎研究，並びに新規接合プロセス技術の開発が喫緊の課題となっている．本研
究では，プラズマ，ラジカル源，超音波，レーザー光等のドライプロセス，並びに液相プロセスを包含する多種多様な接合プロセスを用いて，非金属の接合状態や接合強度に及ぼす重要因子を評価し，最終的に非金属異材接合に関する新規プロセス技術
をブレークスルーすることを目的とする．具体的にはプラズマ等のドライプロセス，並
びに液相プロセスを用いた非金属異材接合に関する基礎的実験を行い，接合状態，
接合強度等を詳細に評価し，接合メカニズムを明らかにするとともに非金属異材接合に関する新規プロセス技術の実用化を目指す．
【成果概要】
本年度は，大気圧非平衡プラズマジェットを用いた接合プロセスである「プラズマ熱圧着法」の開発を行い，本接合法を用いた金属－有機材料接合の実現とその接合メ
カニズムの解明に関する研究を行った．これまでに，ステンレス（SUS304）とポリカー
ボネートを用いてプラズマ熱圧着法，抵抗加熱による熱圧着法と接着法で接合を行い，引っ張りせん断応力を測定した結果，プラズマ熱圧着法では接合強度を格段に向上可能であることを確認している．そこで，金属・有機材料表面へのプラズマ照射効果を調べるため，それぞれの材料表面の分析を行った．プラズマ照射前後の金属表面観察を行った結果，プラズマ照射後は照射前に比べて，表面粗さの増大とともに，酸素
原子数濃度増大が確認された。また，有機材料表面においては，C=O などの酸素官能基が付与されていることが明らかになった．これらの結果から，プラズマ熱圧着法を用いることによる接合強度の向上は，金属材料表面の表面粗さ増大による物理的な効果（アンカー効果）と，有機・金属材料表面に付与された酸素官能基による化学的な効果との相乗効果によるものと考えられる．さらに，産業応用を念頭に炭素繊維強化樹脂（CFRP）と金属(SUS304)に大気圧高周波プラズマジェットを照射し圧接したところ，従来の熱圧着に比べ極めて高い引っ張りせん断強度を達成した．

先導的重点課題・研究報告書（溶融加工プロセスでの業後割れ発生現象の解明とその防止技術の構築）【研究目的】
凝固割れは、溶接のみならず鋳造や積層造形など金属の溶融加工プロセス中に発生することが知られている。溶接や鋳造の分野では、凝固割れ現象やその発生防止対策に関する多くの報告があるものの、同一の現象であるにも関わらず、異なった解釈や評価がされている点も多い。そのため、凝固割れ現象の本質的な解明、割れ発
生防止の抜本的な解決には至っていない。本研究課題では、凝固割れ機構を詳細に理解し、これに基づき割れ発生防止技術を構築することを目的として実施する。溶接、鋳造、3 次元積層造形等の他分野の専門家とともに、学術領域や技術分野の垣根を超えて実施することで、多様な視点から凝固割れ現象に関する学理の探求や割れ発生防止法を検討する。抽出した課題解決に向けた検討を進め、共通理解に基づく新
たな凝固割れ発生機構やその防止技術、割れ感受性評価法の構築を試みる。
【成果概要】
本年度は、役割分担型として、溶接や積層造形過程での凝固割れに関する感受性評価方法や割れ発生の影響因子について検討を行った。溶接においては、ステンレ
ス鋼における合金元素と凝固割れ感受性の影響を調査し、フェライト量や第二相晶出などの影響が明らかとなった。特に凝固偏析を助長する合金元素であっても、C 量の適切な含有に伴う MC 炭化物の晶出を制御することで、割れ感受性を改善できることを見出した。 また、金属積層造形における凝固割れ感受性評価では、これまでに溶接分野において用いられてきた凝固割れ感受性評価試験を、3 次元積層造形過程のための適正化を行うことで、高温延性曲線を導出可能であることを明らかにした。構
築した手法を用いて凝固割れ感受性を評価し、積層条件に依存した特有の組織形態
が凝固割れ感受性に影響を及ぼすことを見出した。引き続き、溶接、3 次元積層造形等の溶融加工プロセスでの凝固割れ現象の共通理解、割れ感受性評価試験の適正化・確立を目指した活動を行っていく予定である。また、鋳造における凝固割れ感受性について、現在の研究状況、課題について専門家のヒアリング等により情報収集を行った。溶接と鋳造の凝固割れ感受性評価における共通項を精査し、情報共有しながら連携を図り、課題解決向けた取り組みを行っていく。

先導的重点課題・研究報告書（溶接・接合技術におけるデジタルツインに関する研究）【研究目的】
次世代工業革命（Industry Society 5.0 等）の実現に貢献するため、モノづくりプロセスにおける物理現象を仮想空間で再現するデジタルツインの構築が求められている。
それを支援するキーテクノロジーの一つは、数値シミュレーション技術である。本研究では、接合研が開発した数値シミュレーション手法・ソフト JWRIAN と汎用ソフトを活用
して、溶接・接合及び積層における熱プロセス・材料・力学の実挙動を高精度で再現した上、溶接・接合・積層プロセスにおける熱流動、接合部形状、材料組織、応力ひず
みおよび使用時の力学挙動を予測し、それらの実現象を包括したデジタルツインに関する研究を行う。 計画では、下記のテーマを対象として、 (1)溶接熱源・熱流動と溶融形状のデジタルツイン、(2)溶接・接合・積層の溶融形状・塑性形態と熱応力ひずみのデジタルツイン、(3)溶接・接合・積層の熱サイクルと材料組織のデジタルツイン、(4)接合部形状・負荷状態とその力学挙動のデジタルツインという基礎を構築する。
【成果概要】

Performance 28-12(2019)」にて発表した。③劉らは、アルミニウム合金のステーショナ
リー・ショルダー摩擦攪拌接合における残留応力を解析し、国際誌「The International
Journal of Advanced Manufacturing Technology 106 (2020) 1573-1586」にて発表した。
④堤は JWRIAN による溶接残留応力解析結果を考慮した K 値評価を行い「Marine
Structures 71(2020)102733」にて発表した。⑤三上らは、溶接残留応力の数値シミュ
レーションにおいて重要な入力条件である温度分布および温度履歴を精度よく予測するために，複数点の温度履歴の測定結果に基づいて溶接熱源モデルを構築する基本

的な手法を構築し，「Visual-JW 2019」にて発表した．⑥茂田は、粒子法によるスポット
溶接解析の可能性を探った。⑦塚本研はレーザ溶接ならびにレーザブレージングで発生する残留応力を解析するために、JWRIAN をワークステーションにインストールして計算環境を構築した。
来年度からは、数値解析で得られたデータを充実し、データベースを構築すると共に、高速 AI 技術を用いたデジタルツインの形を構築する予定である。

Introduction

SiC (silicon carbide) and GaN (gallium nitride) have a wider band gap than Si, and they are able to withstand both hightemperature and high-frequency operation. There utilization also results in reduced power loss and overall downsizing of thepower electrical equipment. Operation temperatures of Next-Generation SiC power modules can achieve 250 ႏConventionalsolder material, including high-lead solder and most lead-free materials such as Sn-Ag, Sn-Cu, Sn-Ag-Cu, Sn-Bi alloy systems,
are inadequate in terms of electrical conductivity, and none of them deliver the high performance standards required in hightemperature operation. To address the increasing reliability challenges at high-temperature, Ag sinter joining is emerging as apromising interconnection solution for die-attachment, as it possesses superior electrical and thermal conductivity, as well as highmelting temperature properties In addition, Ag sinter joining is more than the sintering of Ag paste, it also includes the interdiffusion processes at the bonding interface which determine the reliability and quality of Ag sinter joining. Among various
metallization layers, Au surface finish is considered an ideal choice for metallizing substrates because Au has high electrical andthermal conductivity as well as excellent chemical resistance. For instance, Au surface finish has been widely used in electrodes,
Si/SiC wafers and printed circuit boards (PCB).
In this study, four kinds of plating processes of ENEG, ENIG, ENEPIG, ENEPIGEG with the same thickness of Au layer(0.15 μm) were designed and sintering with the best result among the five kinds of Ag paste. The grains structure of four kindsof plating Au surface were investigated by EBSD to reveal the mechanism on the improvement of sinter Ag-Au joint. The
mechanism of robust bonding of sinter Ag-Au joint were systematically analyzed via SEM, EDS, TEM and XRD.
2㸬Materials and methods
The micron Ag flakes (average diameter of 2.5 ȝm) and the Ag sub-micro
spherical particles (average diameter of 300 nm) (Fukuda Metal Foil and
Powder Co. Ltd) were prepared as the Ag precursor. Fig. 1(a) shows the
Back-scattered Electron Detector (BSE) image of the Ag content. Au plating
is an exceptional finish for connectors where there is a demand for highreliability and durability. In this study, ENIG, ENIGEG, ENEPIG andENEPIGEG were prepared and coated on a direct bonding aluminum (DBA)
substrate as shown in Fig. 1(c) and (d). The thickness of electroless Ni plating
was set as 7 μm for all of the Au plating process. In the case of ENIG,ENEPIG, the thickness of Au was set at 0.15 μm by the one step process of
IG. For the ENIGEG, ENEPIGEG process, the Au layer was firstly plating
by IG process with a thickness of 0.05 μm and then with the EG process with

Fig.1 the image of the Ag content andsintering processa thickness of 0.1μm. The thickness of Pd by electroless palladium phosphorus plating was 0.1μm in the ENEPIG andENEPIGEG process.

3㸬Results and discussions
Fig. 2(a) (b) (c) and (d) shows the highmagnification SEM image of ENIGEG, ENIG,ENEPIGEG, ENEPIG plating surface, respectively. It
is clearly shown that the ENIGEG and ENEPIGEG
have a rough surface and the Au grains of ENIG andENEPIG surfaces are clearer than those of the
ENIGEG and ENEPIGEG. Fig. 2(e) (f) (g) and (h)shows the cross-section of sinter Ag joining on adifferent Au plating substrate corresponding to Fig.
2(a) (b) (c) and (d), respectively. The Ag flake paste
has already been sintered into a uniform andcontinuous porous structure, which indicates the Ag
paste possesses a favorable sinter-ability at low

Ag flake paste on the four kinds of Au plating substratetemperatures without any assisted pressures. From thecross-section image, the Au layer of ENIG shows adenser Ag grain structure than that of ENIGEG.
ENEPIG shows a larger grain size than ENEPIGEG
plating process. On the other hand, there is somesintered Ag covering on the Au surface by ENIGEG
and ENEPIGEG, and it is worth noting that the Au
layer appears a fragmented structure with some voids
inside the Au layer as seen in Fig. 2(e) and Fig. 2(g).
respectively. The fragmented structure of Au layer
may be attributed to the Au diffusion into the sintered
Ag paste. The voids inside the Au layer after sintering
may be induced by the rough surface of ENIGEG
which should accelerate the occurrence of Ag-Au

interface diffusion. For the case of ENIG andENEPIG, as depicted in Fig. 2(f) and (h), respectively, the Au layer presents a compact structure which tightly bonds to thesintered Ag layer, rather than severe voids inside the Au layer.
To further determine the relationships between the different diffusion processes and why robust bonding was achieved on the
ENEPIG substrate, the grain structures of ENIGEG, ENIG, ENEPIGEG and ENEPIG plating surface were characterized by
EBSD observation. Four surfaces consisted of crystalline particles that were randomly oriented relative to each other, meaningthat the all the Au plating layer was polycrystalline. The EBSD inverse pole figure (IPF) maps of the ENIGEG, ENIG,ENEPIGEG and ENEPIG plating surface are shown in Fig. 3(a) (b) (c) and (d), respectively. Fig. 3(e) (f) (g) and (h) shows thepole figures corresponding to the Fig.3 (a) (b) (c) and (d), respectively. The results reveal that the texture orientation for the fourkinds of Au plating is quite similar (111) but ENEPIG displays a more pronounced grain orientation (111) than the others. It wasreported that the interfacial free energy of Ag (111) / Au (111) was higher than those of the other grains. Ag atoms are more
readily diffused into the Au (111) reducing the high interfacial free energy by forming a stable Ag-Au solid solution. The Au
grain orientation effect on the shear strength of the Ag-Au joint warrants further investigation and study.
On the other hand, Fig. 3(i) (j) (k) and (l) shows the grain size distributions for the ENIGEG, ENIG, ENEPIGEG and ENEPIG－ 14 －

plating layer, respectively. The average grain size for the ENIGEG, ENIG, ENEPIGEG and ENEPIG was measured at 0.07 ȝm,
0.09 ȝm, 0.04 ȝm and 0.12 ȝm, respectively. Usually, for the grain structure of bulk metal, the smaller the grain size, the moregrain boundaries and the grain boundary diffusion can easily occur because of less energy consumption, which is easier thanlattice diffusion. The diffusion rate of Ag atoms into the ENEPIGEG was faster than that of the ENEPIG, and the ENIGEG was
faster than that of the ENIG due to the much smaller Au grains. Usually, the boundary diffusion plays a negative role in Au-Ag
sintering since a brittle bond line will be created. Many studies have also confirmed that mass Ag-Au interface diffusion will leadto a decrease of shear strength. The grain boundary diffusion can significantly degrade the bonding strength because it can quickly
consume massive Ag and create weak bonding necking at the bonding interface. Moreover, faster grain boundary diffusion leads
to more Ag atoms consumption, resulting in smaller interface necking size. ENEPIG possesses a larger grain size than th others,
leading to less grain boundary diffusion and thus resulting in the highest die bonding strength.
4㸬Conclusion
In this study, four kinds of plating processes of ENEG, ENIG, ENEPIG, ENEPIGEG with the same thickness of Au layer(0.15 μm) were designed and sintered to Ag paste. The best die shear strength was obtained at 33.9 MPa at a sintering temperatureof 250 ႏwithout pressure in air. The significant increase in bonding strength is primarily ascribed to the growth of Au grain size
and a smooth surface condition without like voids and defects, which reduces the grain boundaries on the Au surface thus
reducing the grain boundary diffusion of Au-Ag. The robust bonding of Ag-Au joints on ENEPIG substrate was attributed to thelarge Au grain size of ENEPIG, and a good surface condition, as well as the Pd layer which prohibits Ni diffusion into the Au
layer during the aging process.

calculation. Fig. 3 compares the geometries of the clinched joint between experiment and simulation. As shown, the simulated
undercut and neck thickness correlate well with experiment.

3.2 FE simulation of clinching process with adhesive

To simulate the clinching process with adhesive, a layer of element is used to represent the adhesive layer between the two
metal sheets, as shown in Fig. 4. The adhesive layer was divided into several parts to allow seperature under compression. Fig.
5 shows the geometry comparison of the experimental and simulated clinched joint with adhesive. The simulated undercut agrees
well with expriment. However, the simulated neck thickness shows large error. This may result from the material properties ofadhesive, which was currently simplified as a solid part, but should be treated as viscous fluid with proper equation of state (EOS).
The feasible of simulating the clinching process with adhesive is validated in the current stage of this research, future research
will focus on improving the simulation accruacy.

1. Introduction
The focus of the paper is to evaluate the effect of the Young’s modulus ratio between the ferritic matrix and the inclusion,
therefore, two non-metallic inclusions are considered: a hard inclusion (i.e. Al2O3) and a soft inclusion (i.e. MnS). The sample
consists of a cylindrical ferric body with a spherical inclusion at the centre. The ratio between the sphere radius and the cylinder
radius is 0.20, giving a volume fraction of 0.005. According to Cerullo and Tvergaard, increasing sizes of the volume fraction of
the inclusion reduced the damage factor estimated with the modified Dang Van criterion, probably due to the fact that a bigger
inclusion reduces the stress peak for the matrix in the reference cell. Future works will investigate this aspect. The cylinder isconstrained at the base along the direction y and rotations are prevented. A prescribed displacement along y is imposed on top of
the cylinder, giving a maximum nominal axial strain of 25%. Different values of uniform pressure are applied on the lateral andtop surface of the sample, in order to study the effect of a hydrostatic component of the stress (see Fig.1a). In detail the pressure
values are: -100 MPa, -50 MPa, 0 MPa, +50 MPa and +100 MPa. The mesh consists of 126144 hexahedral elements with reduced
integration (i.e. Abaqus element C3D8R), for a total amount of 135501 nodes (see Fig.1b). For sake of comparison, the ferrite
has been considered alternatively isotropic and anisotropic to evaluate the influence of an anisotropic elastic tensor. The elastic
constants are assumed accordingly to Tjahjanto et al. for the anisotropic elastic tensor and for the crystal plasticity constants(Table 1). In detail, perfect plasticity was assumed. The constants for the isotropic behaviour of the ferrite and the Al2O3/MnS
inclusions were given in Table 2.

2. Results and Discussion
The response of the sample is checked in terms of nominal stress vs. nominal strain curves, varying the crystallographic
orientation of the ferritic matrix. The same approach is adopted for the analyses in the subsequent section. The first set of analyses
does not consider the effect of a superimposed hydrostatic pressure and the only loading condition is a prescribed displacement
along the y-direction applied on top of the cylinder. Perfect elasto-plastic behaviour is considered, since the interest of the work
is to check whenever the first plastic slip takes place. In fact, the generation of local plastic deformation in the surrounding of the
inclusion gives useful information on the fatigue life of the material in terms of nominal stress and crack location site. As acomparison, the graphs in Fig. 2 report an additional dashed curve obtained considering the sample without inclusion andassigning to every element a different crystallographic orientation, in order to simulate a polycrystal stress-strain curve. The firstplastic slip in the polycrystal analysis is indicated with a yellow marker on the curve. The first step is to compare the material
response without the inclusion considering isotropic elasticity or anisotropic elasticity. It is possible to notice that the elastic
anisotropy varies the inclination of the elastic parts of the stress-strain curves, depending on the crystallographic orientation,
which consequently modify of the size of the elastic domain in terms of strain. This last aspect can be better understood byobserving Fig. 2. Here, the black markers indicate the nominal yield stresses which, compared with Fig. 2, take place at different
nominal strains. The effect of the harder and softer inclusions can be observed in Fig. 2. The differences in Young’s modulus
between the ferritic matrix and the Al2O3 or MnS inclusions alter the stress field in the surrounding of the inclusion, generatingsome stress localization. This triggers the activation of some slip systems, giving a different response compared with the analyses
without the inclusion. Fig. 3 summarises the results obtained in the analyses. In detail, the graph reports the normalized nominal
yield stress σy against the nominal yield stress of the isotropic elastic analyses without the inclusion (i.e. Fig. 2). It can beconcluded that the Al2O3 inclusions are in general more harmful since they trigger the generation of plastic deformation at lower
stress regime. However, depending on the Euler angles set, the differences in yield stress between the Al2O3 and the MnS－ 159 －

inclusions seems to become closer when the BCC cubic structure is rotated to give an alignment between cubic diagonal and thepulling direction. In case of perfect alignment, the MnS inclusion seems to be more harmful (see Fig. 3).

Thermal Fatigue Performance and Crack Propagation Behavior of Brake Disc for
350 km/h High-Speed TrainΎ⳹኱Ꮫ  Jinnan Wang᥋ྜ⛉Ꮫ◊✲ᡤ 㯞ᑀ⥴
1. Introduction
It is very important to evaluate the thermal fatigue properties of materials efficiently and timely.
In this paper, the composition of cast steel for brake disc of 350 km/h high-speed train is improved
and its thermal fatigue property is studied. Based on the experimental results and the analysis of crack
propagation behavior, a range of thermal fatigue initiation cycles suitable for cast steel brake discmaterials is obtained. The crack length can be observed by choosing a number of cycles in this range
as an index to evaluate thermal fatigue performance. The factors to improve the thermal fatigue crack
growth of materials were obtained by analyzing the crack tip morphology and composition.

A Recommendation to Consider Phase Transformation for Numerical Simulation of
Residual Stress in HSLA Steel Joints
Chongqing University, DENG DEAN㸦㒭ᚫᏳ㸧
JWRI, Osaka University, Ninshu Ma㸦㯞ᑀ⥴㸧
1. Introduction
High-strength low-alloy (HSLA) steel have been extensively used in cars, buildings, ships, bridges and other structures. Solidstate phase transformation (SSPT) including martensitic transformation, bainitic transformation and ferritic transformation occur
during the welding process of HSLA structural steels. Researches [1, 2] showed that the SSPT have a significant influence on
the formation of welding residual stress. However, it is always difficult to obtain essential material data for the SSPT modeling.
In engineering industries, there is a need for a principle to determine whether it is necessary to take SSPT into account in welding
simulation. In this study, the effect of SSPT on the prediction of welding residual stress was investigated in a series of grade of
HSLA structural steels such as Q345, Q420, Q690 and Q960 steel. A reference value of carbon equivalent was recommended
for determining the necessity of considering SSPT in the welding simulation of HSLA structural steels.
2. Experiments
A welded joint made of Q345 steel was fabricated and the welding residual stress of the joint was measured to validate thesimulation results. Welding experiments were not carried out for Q420, Q690 and Q960 steel. Numerical simulations were
performed instead. The chemical composition of those steels is shown in Table 1. The equivalent carbon content is calculatedusing Eq. (1). The surface of Q345 plate was melted by gas tungsten arc welding (GTAW) without filler metal. The dimensionof the welded joint is 200 mm × 200 mm ×10 mm. Welding process was performed at room temperature without preheating. The
welding current is 189 A and the voltage is 13V. The welding speed is 2.4 mm/s. Weaving welding method was used to obtain awider weld bead. The residual stress distribution on the welded surface was measured using hole-drilling method. The diameterof the drilled hole is 1.5 mm and the depth is 2 mm.

Fig.1 Peak temperature distribution(1)

Based on Sysweld software, the coupled thermal-metallurgical-mechanical simulation approach was used in this study. The
martensitic transformation was considered using Koistinen-Marburger equation. The Leblond equation, which is a simplified
derivative expression of Johnson-Mehl-Avrami equation, was used for diffusion-controlled transformation such as austenitic
transformation, bainitic transformation and ferritic transformation. The SSPT models were calibrated using CCT and SHCCT－ 225 －

diagrams from literatures. In this study, the yield strength change due to SSPT was considered. The strain hardening behavior aswell as the influence of SSPT on strain hardening recovery was not taken into account. A perfect plasticity model was adopted.

4. Results and Discussion
As shown in Fig. 1, the comparison of predicted peak temperature distribution matches well with the macrograph of Q345 steel
welded joint. Fig. 2 shows the measured residual stress profile using hole-drilling method and the simulation results across theweld center on the welded surface. The predicted and measured residual stresses are generally in good agreement in both
longitudinal and transverse direction, which validates the accuracy of simulation approach. In the weld metal (WM) and heataffected zone (HAZ),high tensile stress can be observed in the longitudinal direction. The predicted longitudinal stress withconsidering SSPT is 100 MPa higher than that without SSPT because newly-formed bainite have higher yield strength. The
measurement located between the predicted results in those two cases, as shown in Fig. 2(a). It shows that SSPT has a minor
influence on residual stress of Q345 steel welded joints.
A normalized R parameter is calculated following Eq. (2) for the convenience of comparing the influence of SSPT on residual
stress among Q345, Q420, Q690 and Q960 steel welded joints. Fig. 3 compares the distribution of R parameter in respect of
longitudinal stress of a series of HSLA steel welded joints. It is clearly shown in Fig. 3) that the R parameter declines from about
1.0 to 0.2 in the WM and HAZ with the increase of material strength, which indicates the grown in importance of considering
SSPT in the welding simulation. For Q690 and Q960 steel welded joints, the predicted results have a significant reduction when
considering SSPT. The reduction in the WM and HAZ is owing to the volume expansion during martensitic transformation which
is dominant in the SSPT of HSLA steels with higher strength. As the SSPT has a minor influence on the residual stress of Q345
and Q420 steel joints but a significant one on Q690 and Q960 welded joints, we can therefore suggest a carbon equivalent of 0.5
for determining the necessity of considering SSPT in numerical model. The recommendation can be useful in engineering
application to save the time and money for the establishment of SSPT model.

1) A carbon equivalent of 0.5 was recommend for determining the necessity of considering SSPT in the prediction of welding
residual stress of HSLA structural steels, above which the SSPT should be taken into account to improve the accuracy ofsimulation works.
2) For HSLA steels with higher yield strength, SSPT has a significant influence on the prediction of welding residual stress. The
simulation result tends to be conservative without considering SSPT.

attention because of the requirement of industrial
development. To acquire a practical and much more
efficient GMAW process, increasing the welding current
and wire stick out length is the easiest and most effective
way. For example, in MIG welding process, withincreasing the welding current, the metal transfer process
will change from short-circuit transfer and globulartransfer to spray transfer. When the current exceeds 400A
(for φ1.2mm steel wire), the metal transfer will change torotating spray transfer, which is shown in Figure 1. The
project or stream spray transfer is widely used in highquality welding technology. With continuing to increase
the welding current, unstable rotating-spray transfer
phenomenon happens, which has been avoided because of

technologies are widely used in welding technology forseveral years [2], and it is a reasonable way to control thehigh-current GMA metal transfer process by using an
external magnetic field. In this study, numerical simulation
method based on computational fluid dynamics (CFD)
including volume of fluid (VOF) method is advantaged tomake it possible to estimate the magnetic controlling
behavior in high-current GMAW.

A simplified 3D mathematical model including
volume of fluid (VOF) with considering constant, 100Hzand 500Hz alternating square wave external axial
magnetic fields is proposed for high-current GMAW
process. Multi-Fluid VOF model is selected to calculate
two independent conservation equations of metal and gas
phases about mass and momentum.The arc angle is set to20°㸪and the electrical conductivity of arc region is set toa constant value of the argon plasma conductivity at

The welding current is 400A, and the wire feeding rate

applying an enternal 0.02T axial constant magnetic field,
which is shown in Figure 4(b), the rotating frequency(d) With external 500Hz alternating square wave form

maintains almost the same, however, the deflected angle
exceeds from 27.8° to 37.5°, hence more spatters generate
in the GMAW process. The 100Hz magnetic field
influences the metal transfer process in a different way. It
can be seen in Figure 4(c) that the low frequency magnetic
field makes the metal rotating direction shift every 5ms,
and the deflecting angle can then be reduced under themagnetic field control effect of alternating. Figure 4(d)shows that the external 500Hz alternating magnetic field
can not change the metal rotating direction anymore
because of the large inertia of molten metal.

5 Conclusion
With the help of the numerical simulation method basedon computational fluid dynamics (CFD) including volumeof fluid (VOF) method, we build a 3D simplified model ofmagnetic field control high-current GMAW metal transfer
process. For metal rotating spray transfer of 400A MIG
welding process, constant axial magnetic field influences
the rotating transfer process by increasing the rotating
angle which will finally increase the spatter. Lowfrequency axial magnetic field will drive the metal liquidcolumn to shift its rotating direction with same frequency
while the high-frequency axial magnetic field can only
drive the arc to shift its rotating direction.

Extraordinary reinforcing effect of carbon nanotubes in aluminium matrix composites
assisted by in-situ alumina nanoparticles
Prof. Biao Chen
Northwestern Polytechnical University, China
1. Introduction
As revealed by many studies, the homogeneous dispersion of the carbon nanotubes (CNTs) can berealized by high energy ball milling (HEBM) with Al powder. HEBM of CNTs and Al powder constantly
produces fresh Al surfaces, which have acute reactivity for oxygen. As a result, significant AlxOy phases
form in situ, supported by a considerable increase in oxygen content (the room temperature solubility ofoxygen in Al is essentially zero. These AlxOy phases are ultrafine and presumably also amorphous as they
are not detectable by transmission electron microscopy and X-ray diffraction, despite the exceptional
oxygen content (~0.7 wt.%). However, informed by a preliminary study, we have found that these ultrafine
amorphous AlxOy phases can be precursors for the in-situ formation of ultrafine (~30 nm) and stable
γ−Al2O3 nanoparticles, subject to a suitable isothermal consolidation process by spark plasma sintering.
This paper will focus on the realization of our design hypothesis and the identification of the underlying
mechanisms.
2. Experimental procedure
Al powder (d 20 μm, 99.7% purity, Kojundo Chemical Laboratory CO., Japan) and multi-walled CNTs(~15 nm in diameter and 1-2 Pm in length, Baytubes C150P, Bayer Material Science, Japan) were used as
starting materials. Different batches of Al powder, CNTs (1, 2, 4, and 6 wt.%, or 1.2, 2.5, 5 and 7.5 vol.%estimated by using the density 2.0 g‧cm-3 for multi-walled CNTs) and stearic acid (process control agent, 1
wt.% or 2.7 vol.%) were mixed for 2 h using a rocking milling machine (RM-0.5, Seiwa Giken Co. Ltd.,
Japan). Each mixture was then sealed in a zirconia jar (500 mL) together with 10-mm diameter zirconia
balls (ball to powder mass ratio: 5:1) for HEBM. The jar was aerated with a flow of high-purity argon gas(<0.001 wt.% O) to protect the mixture from excessive oxidation during HEBM. The HEBM was carriedout at 200 rpm for 24 h with a cool-down break of 5 min in every 15 min to avoid overheating. The ball
milling time for the mixtures Al-5vol.%CNTs and Al-7.5vol.%CNTs was extended to 48 h due to increased
CNTs. For comparison, pure Al powder was ball-milled under the same conditions. The median diameter(D50) of milled powder was measured using a Laser Scattering Particle Size Analyzer (LA-950, HORIBA
Ltd., Japan). The milled powders were consolidated by spark plasma sintering and following hot extrusion.
3. Results and discussion

In the fabricated Al MMCs in the present study, ex-situ CNTs play a major role to enhance
the strength, while in-situ γAl2O3 nanoparticles contribute a secondary portion, leading to thehigh strength. During deformation of composites, γAl2O3 nanoparticles perform a significant partfor the formation of dimples, while CNTs auxiliarily reduce the growth of dimple boundaries,
retarding the rapid expansion of cracks. The cooperation of CNTs and γAl2O3 produces both hightensile strength and good ductility of Al MMCs. Consequently, ex-situ CNTs and in-situ
nanoparticles act in concert to achieve simultaneous excellent strengthening and toughening effect.
Fig. 1 compares the toughness between Al-CNTs-γAl2O3 MMCs and other Al MMCs. The－ 237 －

toughness can be estimated by the product of σUTS × elongation for ease of comparison. The
advantages of the novel Al-CNTs-γAl2O3 MMCs are clear due to the combined effects of the
CNTs and γAl2O3 nanoparticles. It is noted there are also some other occasional studies that reportsimultaneous high strength and high ductility in CNT-reinforced Al MMCs using 2xxx alloys as
matrices. For example, He et al. achieved high tensile yield strength of 443 MPa, ultimate tensile
strength of 560 MPa and fracture elongation of 10.2% by a cryogenic milling in a 1.0 wt.%
CNTs/2009 Al alloy-T4 composite (as marked by the quadrilateral star in Fig. 1). In thesecomposites, the fine precipitates (mainly Al2Cu and Al2 CuMg) in nanoscale act as a similar role tothe in-situ Al2 O3 nanoparticles that they can strengthen Al-CNTs MMCs by dispersion
strengthening. These results imply that the co-strengthening of ex-situ CNTs and in-situ nanoprecipitates can be an applicable approach for other CNT-reinforced MMCs to fabricate highstrength and tough materials.

4. Conclusions
A new class of Al MMCs reinforced by ex situ introduced carbon nanotubes (CNTs) and in situ formed
γAl2O3 nanoparticles have been developed, which consistently achieved high tensile yield strength(515±17 MPa), high tensile strength (542±4 MPa), high elastic modulus (95.6±1.7 GPa) and excellent
elongating (10.4±0.8%) with density (2.735±0.002 g·cm-3) similar to that of pure Al. For the first time, Al
MMCs are made to be comparable to the benchmark high-strength AA7075-T6 in terms of both the tensile
strength and elongation but with much higher elastic modulus and lower density.

A FEA on the influences of cooling conditions in laser metal deposition of a directionally solidified superalloy
Tsinghua University Baohua Chang
Osaka University Ninshu Ma
1. Introduction
Directionally solidified (DS) nickel-based superalloys have been widely employed in manufacturing the critical hotsection parts such as blades in aeroengines and gas turbines with working temperatures higher than 1000 qC. Various
defects, such as wear, cracks, and burn-through, may take place in these superalloy parts during service under the crucial
working conditions, which make the parts fail. Considering the very high cost involved in replacing the failed parts withnew ones, the repairing of such defected parts have been considered as a better solution.
Among various repairing processes for turbine blades, such as gas tungsten arc deposition, plasma arc deposition, etc.,
laser metal deposition (LMD) has been considered as a promising technology thanks to the more concentrated heat input,
lower stress and distortion, high precision, and high flexibility in production. So far, quite a lot of research has been
carried out on the LMD of the directionally solidified nickel-based superalloys. The ideal LMD microstructures of thedeposits on the DS superalloys should be defect-free columnar grains directionally grown in the same crystallographic
orientation with the DS superalloys substrates. Cracks in the deposits have been one of the main defects to be tackled in
the LMD of such nickel-base superalloys due to their high sensibility to cracking.
It has been shown by existing experiments that the cracking sensibility could be reduced to some extent by controllingthe heat input in LMD of a directionally solidified nickel-based superalloy. One of the research carried out at Tsinghua
has shown that an additional enhanced cooling on the substrate in the LMD of a DS alloy could reduce the cracking
sensibility in the heat affected zone (HAZ). However, it has not been revealed how the cracking behavior was related tothe internal stresses when the additional cooling condition was used.
In this paper, the effects of the auxiliary cooling applied to substrates on the temperature and stress fields developed in
the LMD of a directionally solidified superalloy IC10 were analyzed using finite element method, in order to correlated
the cracking behaviors with various cooling conditions. The research is of significance for the process optimization andmetallurgical quality control in repairing or manufacturing the superalloy components.
2. Research approaches
The laser metal deposition set-up is schematically shown in
Figure 1. Directionally solidified nickel based superalloy IC10,which has a high service temperature higher than 1100 ºC wasused in this study.
A forced cooling apparatus was designed to realize the fastcooling on the substrate, as shown in Figure 2. During LMD, a
substrate was clamped on the apparatus, while the cooling waterflowing beneath the substrate and quickly taking the heat away.
In contrast, the substrate specimen was fixed on a clamping jig
made of a carbon steel in the conventional LMD process.

deposition process

The numerical analysis was implemented by using thethermal elastic-plastic finite element method (FEM) solver
JWRIAN-hybrid developed by authors.
The finite element meshes were constructed for the two
LMD processes. The dimensions of the substrates were 70 mm
× 24 mm × 4 mm, and the profiles of deposits were incorporated
in the finite element meshes according to their real dimensions
obtained experimentally. Finer elements were used for thedeposits and heat affected zone where high thermal gradients
exist, while for the substrate region far aw ay from thedeposit/substrate interface, the mesh sizes were increased.
Different thermal boundary conditions were used to model
the two different cooling conditions. For conventional coolingcondition, a convective heat transfer coefficient of 1000 W/m2K
was applied on the bottom surface of specimen, while for force
cooling conditions, a constant temperature of 20 ºC wasassumed for the bottom surface of the substrate. Except for thebottom surface, a natural convection coefficient of 100 W/m2K
was applied on the other surfaces of the substrates.

3. Results
Figure 3shows the distributions of temperature in the cross sections of substrates after having reached the quasi-steadystate under the two cooling conditions. It can be seen that the distribution patterns of temperature are similar for the twocooling conditions, the temperatures are the highest in the deposits, then lower at the deposit/substrate interfaces, andfurther decrease in the substrate with the increase of distance to the interface. The cooling condition mainly affects thedepth of the high-temperature region in the substrate, which is notably reduced by using the forced cooling in comparison
with that obtained under conventional cooling conditions.
Numerical results showed that the high tensile stresses in thespecimens are mainly generated during the cooling period.
Therefore, the distributions of the transversal stresses (ıy) in the
cross sections of substrates at different cooling stages arepresented in Figure 4 for the LMD with two different coolingconditions.
Figure 3. Distributions of temperature in the crossWhen the laser heat source arrives at the position (t=0 s), thesections under two cooling conditions
central part of the specimen is heated and expands. Because such
expansion is restrained by surrounding metals, compressive
stresses are developed around the deposit/substrate interface. The
region with high compressive stress (greater than 300 MPa) issmaller for forced cooling condition than that for conventionalcooling.
After a short cooling process, the compressive stresses aroundthe interface region will change to tensile stresses because of thedecrease in temperature and accompanying metal shrinking. The
maximum tensile stresses exist in the narrow regions nearby thedeposit/substrate interface. When the forced cooling condition isused, the maximum tensile stress is smaller and the high-stressregion in the substrate is shallower than those obtained underconventional cooling condition.

With the increasing of cooling time (t=0.65-1.4 s), the regions with high tensile stress enlarge in both thickness andwidth directions within the cross sections, as a result of the gradual increase of tensile stress with time. Obviously, for allof these time points, the highest tensile stress and the dimensions of the region with high-stress region are both smallerwhen the forced cooling conditions is used.
It is revealed by the present numerical analysis that high tensilestresses are developed around the deposit/substrate interface
during cooling of LMD process, where the temperatures are still
high, as shown in Figure 5. As a result, the weak eutectic structurein the heat affected zone will be broken and cracks will form
along the columnar grains boundaries. The introduction of theforced cooling in the present study on the bottom surface of a
substrate by flowing water will decrease the temperature andreduce the high-temperature zone in the HAZ of the substrate,
which means a reduced volume of melted eutectics formed
between columnar grain boundaries during LMD. Meanwhile,the forced cooling also reduces the tensile stress and the thicknessof the region with high tensile stress. Such alleviation effects inboth thermal and mechanical aspects, which are also shown in
Figure 5, contribute to the mitigation of cracks in HAZ by the

4. Conclusions
1) The liquation cracks could be effectively mitigated by applying forced cooling on the bottom of substrates during
LMD of the directionally solidified superalloy IC10.
2) The forced cooling reduces the highest temperature and tensile stress in the substrate, and also minimizes theregions with high temperature and tensile stress, which contributes to the reduction of liquation cracks in LMD ofthe directionally solidified superalloy.

1㸬Introduction

With the consumptions of global energy, weight reduction and energy saving had become a great tendency in the future
manufacture of automobile. Therefore, more and more light composite materials were introduced in the main body of
automobile. Obtaining a reliable joining between steel and composite materials was significance to achieve this energy
saving goal. Laser welding steel to composite material could avoid these disadvantages and had a great potential in thepractical industry due to the high automation of laser.
In this research, dual phase steel DP590 was joined with CFRP by laser welding technology. The laser could provide a
focused and dense heating effects. By the irradiation of laser on the steel, the resin could be melted and bonded with thesteel sheet when the welding process was finished. The influence of laser power on the welding formations, interfacial
microstructure evolutions and interfacial thermal cycles were investigated. Then the relationships between interfacial
microstructure evolutions and thermal cycles were clarified. After that, strength of joints produced under various laser
powers was evaluated and the reason for the strength variations were analyzed.
2㸬Experiment and numerical process

The HIGHYAG fiber laser and the AlmegaAX-V16 robot was assembled as laser welding system as seen in Fig. 1(a).
To obtain a larger heating area, the laser was defocused as +93mm and the diameter of the defocused lase spot was about
10mm. During the welding process, the DP590 steel was set at the upper side and the laser would direct irradiate to thesteel surface as seen in Fig. 1(b). To ensure the satisfied bonding
between DP590 and CFRP, fixture was adopted during the wholewelding process and the fixture location was presented in Fig. 1(c).
In this research, the thickness of steel was 1.4mm while it was
3.0mm for CFRP. The matrix of CFRP was composed by the 80% PA6
and 20% carbon fibers. The steel and CFRP sheets were prepared withthe dimension of 75mm(width)* 40mm(length). Before welding, thesteel substrate was polished by sandpaper to remove its oxidation film
and then further cleaned by alcohol. The CFRP sheet was also polishedby alcohol to keep it clear. During the welding, the welding velocity wasset as 5.5mm/s. The adopted laser powers were 300W, 400W, 500W,
600W, 700W and 800W.

0.6mm*0.6mm*0.4mm was divided in the laser direct heating zone while coarser meshes with the 1.6mm*0.6mm*0.4mm
were divided in outer region to shorten the calculation duration based on the acceptable accuracy.

3㸬Results and discussions

To better analyze the influence of laser power on microstructure
evolutions, observations of interface was conducted by SEM andcorresponding experimental results were presented in Figs. 3 andFig. 4. Fig. 3 showed the interfacial microstructure for the joint
produced under the laser power of 400W. It could be clearly foundthat a satisfactory bonding was occurred in the interface since anobvious gap could be seen in the steel/CFRP interface. The resin in
CFRP was fully melted and had a good connecting with steel
substrate which was attributed to its enough high peak temperature
under the laser power of 400W.

Fig. 3 Microstructures at the CFRP/steel interface
under 400W

When the laser power was 600W (Fig. 4). It could be found thatthe microstructure in interface was similar with that of joint
produced under the laser power of 400 (absence of debonding
defect). The microstructure for the joints produced under the laser
powers of 400W and 600W indicated that these laser powers weresuitable for the joining between steel and CFRP. Above all, a larger
porosity was obtained in the middle interface as seen in Fig. 4(b).
DTA measurement results were seen in Fig. 5. It could be
figured out that the melting temperature and the initial thermal
decomposition temperature of the resin are ႏ and ႏ

respectively. Fig. 6 showed the simulated temperature evolutions at
the center of the interface under different laser powers. With theincrease of laser power, the interfacial temperature increased
gradually. It was obvious that under the laser power ranging from
300W to 800W, the peak temperature at the interface was higher
than the melting point of the resin matrix, indicating the formationof resin-steel bonding was possible under these welding conditions.
However, when the laser power was 800W, the peak temperature at
the interface exceeded the decomposition temperature of the resin

matrix was ႏ indicating 800W laser power would causesignificant strength loss of the CFRP material. Therefore, the laser
power should be controlled within the range from 300W to 700W.
4㸬Summary
1. Dissimilar material joining of CFRP to DP590 was
successfully realized by laser welding process.
2. Thermal-mechanical coupled simulation of the laser welding
process was performed and a laser power range was determined tocontrol the peak interface temperature above the melting point but
below the decomposition temperature of the resin matrix.

Prediction of critical velocity for Cu/Al cold spray interface by first principle calculations
す༡஺㏻኱Ꮫ Chengsong Zhang᥋ྜ⛉Ꮫ◊✲ᡤ   㯞 ᑀ⥴1㸬Introduction
Cold spray is high deposited rate coating technology, in which spray particles in solid state are deposited by plastic impact ona substrate. In the present work, the formation of Cu/Al cold spray interface was attempted to investigate by the first principle
calculation. The critical velocity of Cu/Al cold spray was predicted by the calculation of substitution energetic barrier between
Cu and Al. In addition, the Al-Cu intermetallics potentially formed in the interface were also predicted by first principle
calculations. The purpose of this work was to provide a simple and workable method to predict the critical velocity of cold spray.
2㸬Calculation details
In this work, the energetic variation in the process of a Cu/Al atom
crashed into Al/Cu surface was calculated. Before we carried out thesecalculations, the surface structures of Al and Cu should be clarified. Here,the surface energies of three main lattice planes, i.e. (111), (200) and (220),
were considered according to XRD spectrum of Al and Cu. The plane (111)
was the predominant surface plane due to its lowest surface energy (0.69eV
and 1.31eV for Al and Cu (111) plane, respectively. The results were notshown in the present work). Therefore, plane (111) was used as surface
structure for the following calculations. All calculations were performed
with CASTEP code based on the density functional theory (DFT). The
surface structure of Cu/Al cold spray were shown in Fig.1. One Cu/Al atom
was located on a fixed position (S0-S13) with a certain distance from the
Al/Cu (111) surface. Then the surface models for each Cu/Al fixed positions
waere geometry optimized and two typical routes were selected toinvestigate the energetic barrier of Cu/Al atom enter into the Al/Cu substrate.

Fig. 1 Calculated surface models for Cu/Al
cold spray with a Cu/Al atom located on a
fixed distance from surface

One route was located on the face centre of three surface atoms and the other is located on the line centre of two surface atoms.
In order to evaluate the interaction between spray atoms, three surface models with different size will be considered, i.e. 1x1,
2x2, and 3x3 surface models. The generalized gradient approximation (GGA) in Perdew-Burke-Eruzerh (PBE) formula wasapplied to describe the exchange-correlation potential. The ion-electron interaction was evaluated by ultrasoft pseudopotentials
of Vanderbilt type, and the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm was chosen to perform geometry
optimizations of these structures. The cutoff energy of 500 eV was used for plane-wave expansions. The k-points mesheswithin
Monkhorst–Pack framework were set as 4x4x4, 4x4x4 for Al (111) surface model and Cu (111) surface model, respectively. The
geometry optimizations were considered to be converged when the energy change per atom, maximum residual force, maximum
atomic displacement, maximum stress were less than 1x10-5 eV, 0.03 eV/Å, 1x10-3 Å and 0.05 GPa, respectively.
3㸬Results and Discussions
Fig. 2 shows the energetic variations during the process of a Cu/Al atom sprayed on the Al/Cu (111) surface with different size.
It can be seen that when a Cu/Al atom comes close to the surface, the energy first decreases and then increases with the decreasein distance from surface. The lowest energy during the process indicates the equilibrium state for Cu/Al atoms adsorbed on the
Al/Cu (111) surface. When the energy reaches to the maximum values and keeping on moving the atoms toward the surface, the－ 244 －

energy drops down rapidly. It reveals the abstractionof surface that dissolving the Cu/Al atoms into thebulk. Therefore, there exists an energy barrier for the
dissolution of dissimilar atoms. When the kinetic
energy of atoms could surpass the barrier, the bondingof atoms will occur automatically due to the energetic
preference. It indicates the spray materials canconnect with substrate successfully. It also can befound form Fig. 2 that the lower energetic barrier for
Cu sprayed on Al than that for Al sprayed on Cu
which is consistent with the available experimental
results perfectly. For the different routes, the energetic
barrier for route 2 is lower than that for route 1, whichindicates that the Cu/Al atoms prefer to enter into thebulk through the line centre of two surface atoms. It isdetermined by the lattice distortion of surface atoms
resulted from the entrance of spray atoms. With thedecrease in size of surface, the difference in energetic
barrier between route 1 and route 2 becomes smaller,
which is attributed to the interaction among sprayatoms. In fact, the size of surface stands for the contact
area between spray materials and substrates. Larger
size corresponds to smaller contact area. It is worthy
to note that the energetic barrier first increases andFig. 2 Energetic variations for the cases that a Cu/Al atom

area. The calculated results indicate the quality of cold spray interface also depends on the surface roughness of spray materials
and substrates. The maximum energetic barrier can reach to 2.20 and 4.61 eV for Cu sprayed on Al and Al sprayed on Cu,
respectively. Since it is impossible to observe the contact state between spray materials and substrate during cold spray directly,
the contacted area is hard to measure by experiments. In order to evaluate the critical velocity of Cu/Al cold spray effectively,
the maximum energetic barrier will be used. Here we use the following equation to evaluate the critical velocity ‫ = ݒ‬ඥ2‫ܧ‬௕ /ܰ‫ܯ‬,where Eb is the energetic barrier calculated by DFT, M is the mole mass of spray materials and N is the number of relaxed atoms

(2) There is a weak covalent bond formed between Cu and Al atoms which indicates the formation of Al-Cu intermetallic
compounds when the Cu/Al atoms are sprayed on the Al/Cu surface.

Effect of the severe plastic deformation on the interfacial microstructure and properties in Al-Ti friction stir weldingࣁࣝࣅࣥᕤᴗ኱Ꮫ ᮦᩱ⛉ᏛᏛ㝔Mingrun Yu኱㜰኱Ꮫ ᥋ྜ⛉Ꮫ◊✲ᡤ Ninshu Ma
1㸬ㅖゝProcessing by severe plastic deformation (SPD) is an effective procedure to modify and to join metals with ultra-fine grained
microstructure. Friction stir welding (FSW) is an innovative welding technique, which joins matrixes by introducing the SPD
into the welds. It has been widely applied to weld dissimilar metals in the past decades. Great efforts were made to regulate theinterfacial structures and intermetallics for better performance of the dissimilar FSW welds. The intermetallic compounds, whichwere commonly observed at the interface of the dissimilar welds, were considered responsible for fracture and the relatively
weak strength of the dissimilar welds in most studies. Cracks tended to nucleate at the interface and propagate along theintermetallic layer leading to fracture due to the lattice defects and high sensitivity to cracks of the intermetallics. In addition, thevolume variation caused by the formation of intermetallics induced the increase of the local stress, which further weakened theweld. In some cases, the intermetallics were found enhancing the interfacial bonding, and the dissimilar metals were joined by
the intermetallic reactions, according to the related studies. The formation of intermetallics could reduce the pseudo bonding andinner defects, according to the former reports. And the lattice mismatch of the interface, as well as the interfacial strain, was also
lowered by the intermetallics. It is in agreement that there is a threshold volume of the interfacial intermetallics for the ultimate
strength of the dissimilar FSW welds. But the value of the threshold volume is still unclear.
In this study, the microstructure and mechanical properties of the interface in the FSW Al/Ti welds were studied. The
differences between the grain structures in the weld nugget and adjacent to the interface were explored. The interfacial phases
were identified according to various experimental results, and the distribution and the formation of intermetallics were discussed
basing on the interactions between the dislocations and atoms. The mechanical properties of the interfacial structures were tested
by nanoindentation. The relationship between the microstructure and mechanical properties was clarified.

FSW was performed on the Al/Ti lap welds in this study. The
AA6061 sheet was lapped on the Ti6Al4V sheet at the retreatingside (RS) during welding, as illustrated in Fig. 1. The Al and Ti
sheets were cut to 75 mm × 250 mm pieces with the thickness of 3
mm and 2 mm respectively. Before FSW, the surfaces of the matrix
sheets were polished and degreased before FSW to remove theoxides and contaminants. Al/Ti FSW was conducted at therotational rate of 1000 rpm and the traverse rate of 100 mm/min,
which were optimized in the former studies. The pin tool was 3.1
mm long with a shoulder diameter of 12 mm. The shoulder plunge
depth was 0.1 mm and the tool tilting angle was 3.0 °. After FSW,
grain structures were observed using the electron backscatter

microscope (TEM), for which the specimens were prepared by the focused ion beam (FIB). The mechanical properties were
tested by the load-controlled nanoindentation with the loading rate of 50 mN/min and a maximum load of 25 mN.

The Al/Ti interface was protruded towards the Ti side, as
shown in Fig. 2. In the SEM images in Fig. 2a, the black

was formed at the interface due to the atomic diffusion andthe Ti fragments. According to Fig. 2b, the grains were
further refined in the MZ with a different preferential

indicated the plastic deformation in the MZ was severer
than that in the NZ. As shown in Fig. 2c, the grain

MZ was 0.63 °, whereas the average was 0.52 ° for the NZ.
Crystal orientations were analyzed according to the polar
figures (PF) in Fig. 2e. The NZ and MZ were bothcomposed of shear textures, whereas different components
were predominant in these zones.

Ti2Mg3Al18 (Fig. 3c) precipitates, were observed in the MZ. The TiAl3 precipitation became predominant due to the limitless
diffusion of the Ti atoms, which was attributed to the hyper-diffusion around the interface. The TiAl3 and TiAl layers wereidentified at the interface, as shown in Fig. 3d&e. TiAl was formed at the interface between the TiAl3 and Ti subsequently. In
addition, TiAl3 and Ti3Al precipitates were found in the TiAl layer. As for the Ti alloy, Į-Ti was identified with Ti3Al precipitates.
This indicated that Al atoms also immigrated into the Ti alloy at the interface.
4㸬⤖ㄽServe plastic deformation introduced abundant dislocations into the weld. Atomic immigration was enhanced by the pipe
diffusion along the dislocations, which was attributed to the lattice distortion and the interaction between atoms and dislocations.
The solutes tended to segregate at the lattice defects leading to the formation of the mix zone and the intermetallic precipitates,as the diffusivity of the solutes was increased. The movement of the grain boundaries was limited by the precipitates. TiAl wasthen formed between TiAl3 and Ti lowering the interface strain. The motion of dislocation was reduced by the finer grain structure
at the interface, which increased the mechanical properties of the interfacial structures.

1. Introduction

Lap joints are widely used in the automotive manufacturing process, its welding deformation
problem have received increasing attention under the lightweight requirement. Generally, the gap
between the top and bottom plate is designed to be the same. However, a small initial deformation of theworkpiece is acceptable to a certain extent in actual production, which result in a variable gap in different
positions. This study is to investigate the effect of initial deflection and gap on lap joint welding induced
deformation.
2. Experimental study

As shown in Fig 1, two sets of plates with same
dimensions (400×100×2.3mm) and converse initialdeflection were welded into lap joints by MAG welding.
One lap joint consists of a flat plate and a convex plate(Case A), which has a larger gap between top plate andbottom plate in the middle of the weld. The other one
was welded by a flat plate and a concave plate (Case B)
with larger gaps at either end. The maximum gap was
0.5mm and the minimum one was zero over the entire
weld in both cases. All the plates were conducted stressrelief heat treatment at ႏfor 3 hours before welding.
Two curved plates with a deflection of 0.5mm wereprepared by wide peening cleaning (WPC) process.

Fig.1 Setup of welding and measurement forlap joints with initial deflection

Prior to welding, tack welding was performed in both cases. The number of tack welds was 5 whichwere uniformly distributed in longitudinal direction, and the size was approximately 10mm in length. A
metal arc gas welding with 80% Ar and 20% CO2 was employed and the welding parameters were 120A
for current, 19V for arc voltage, 40 cm/min for speed and 20 l/min for gas flow. The base metal was highstrength steel (SPH590), and welding filler was YM-60A.
Cross section profile of the lap joints was observed by OM at 3 positions in welding direction asshown in Fig 1. Fig 2 clearly shows the different gap and weld profile at position P1, P2 and P3 of thetwo cases with opposite initial deflection. To obtain the welding deformation, 3D coordinates ofpredefined points on both top and bottom plates were measured before welding and after cooling. By
subtracting the initial coordinates from the final ones, welding deformations were calculated.

4. Results and discussion

Fig. 4 shows the out-of-plane deformation of the three lap joints with various gaps and initialdeflection. It is clear that the deformed form in all three cases is saddle-shaped, with positive angulardeformation and negative longitudinal deflection. And the longitudinal deflection of the bottom plate islarger than that of the top plate. longitudinal shrinkage force from the point of view of the causes oflongitudinal deflection. In addition, comparing the three cases to each other, Case A has the largest outof-plane deformation, Case B the smallest, and Case C somewhere between the two.
