1. Influence of thermo-mechanical processing on microstructure andproperties of Al bulk metallic glassy alloy reinforced Al matrix composite
prepared by powder metallurgy.
Dr. Shimaa Ahmed Abolkassem
Central Metallurgical Research and Development Institute, EGYPT.

1. Introduction
Aluminum alloys have attracted a lot of attention in recent years due to their excellent properties.
However, compared to titanium alloys and steel, these alloys have lower strength and toughness,
which restrict their use. Due to their high strength, large elastic limit, high corrosion resistance,and perfect adhesion with the metal matrix, metallic glasses particles, have recently attracted more
attention as a filling material for Al matrix composite. SPS sintering method has the advantage of
rapid heating rate using uniaxial pressure leading to faster sintering process with maintaining
amorphous phase, which achieve a perfect densification. Hot extrusion is also used to enhance thegrain boundary among the particles and develop the distribution of different filling elements
through the metal matrix composite.

2. Effect of rare earth oxide coated Cu on the mechanical and physical properties of
Cu-TiN and Cu-CNT prepared by spark plasma sintering.
1. Introduction
Copper alloy with high strength and high electrical conductivity is required for many applications,these applications required specified properties, such as strength, high wear resistance, and hightemperature resistance. But all these requirements cannot be achieved by traditional copper alloy.
So, Copper alloy can be enhanced by embedding copper matrix with ceramic particles as astrengthening phase. Hybrid reinforcement from yttrium oxide and titanium nitride ceramicparticles can be used to improve the strength of the composite, but the wettability between thematrix and reinforcement will decrease. For more homogenous distribution of the reinforcement
through the matrix, powder metallurgy and mechanical alloying can be used. Also, coating of
ceramic particles using electroless deposition technique can be used to overcome this problem.
2. Experimental procedure
Cu-0.5%TiN and Cu-0.5%CNT composites were prepared by mechanical milling. Both the two
prepared composite were reinforced with Y2O3 coated copper with two different percents. Yttriumoxide particles were coated with copper particles by electroless deposition bath. Pure copper, Cu0.5%TiN-3or 6% Y2O3 and Cu-0.5%CNT-3 or

composite by powder metallurgy techniques (SPS and Forging)
1. Introduction
One of the worlds concerns these days, is the development of the electronic and energy industries
by getting high strength with high electrical conductivity materials. Pure copper has high electricalconductivity, but with very low strength. Cu50Zr43Al7 metallic glassy alloy has excellent properties
compared to crystalline alloy, as its atomic arrangement has the structural feature of long-range
disorder, without crystal defects. This feature makes it present a series of advantages superior to
crystalline alloy, so it can achieve high strength with high electrical conductivity.

4. Effect of Cu, Mn and Ti addition on the physical properties of FeCoNiSi High Entropy
Alloys prepared by powder metallurgy technique.
1. Introduction
Nowadays, unique material which has excellent mechanical and physical properties compared to
traditional alloys called High Entropy Alloys (HEAs) is widely used. Anew alloy containing
FeCoNi-HEAs have attracted much attention because of their unique magnetic properties andmechanical properties. But, most of the mentioned HEAs, with excellent magnetic properties have
low strength. Some studies, found that the addition of non-ferromagnetic elements could raise thestrength of the alloy, but decrease the magnetic properties of it. Based on the previous studies,equiatomic FeCoNiSi-Cu, FeCoNiSi-Mn and FeCoNiSi-Ti will be prepared by spark plasma

By Lei Hu, Ninshu Ma, Naoki Osawaȵόɷόɑ˖FeCoNiCrAlˈɴόȾόȷɱɋɏȫɻȸ, ࢢȡKeyword: FeCoNiCrAl; Laser cladding; Cracking
1. Introduction
FeCoNiCrAl high entropy alloys (HEAs) are regarded as promising coating materials for traditional steel.
However, the brittle nature always contributes to the cracking of the equiatomic FeCoNiCrAl HEA
coating. This investigation aimed to reveal the effect of substrate type on the cracking behavior of
FeCoNiCrAl HEA high-speed laser cladding (EHLA) coatings. Based on the stress field from the finite
element method (FEM, considering the martensitic transformation of C45 substrate), the cracking
mechanism of the coating on the C45 pipe was clearly revealed.
2. Finite element models
FEM was employed To investigate the effect of martensitic transformation (MT) on the cracking of thecoating. The stress field evolution during the cladding process was explored. Then, the cracking behaviorof the coating was discussed based on the stress evolution. Three cases were calculated. Case 1: The
substrate was C45. The MT of substrate was not considered. Case 2: The substrate was 304SS. Case 3:
The substrate was C45. The MT of the substrate was considered.

Fig. 1 Material properties and mesh of the FE model Fig. 2 Stress distribution of coatings from FEM
The stress distributions of cross section A in Fig. 1 (c) and (d) from the three cases are shown in Fig. 2.
The stress distributions in three directions, including normal direction (ND), transverse direction (TD),and cladding direction (CD), were separated. According to the stress distribution images, the stress in ND(in Fig. 3(b), (e), and (h)) was lower than that in TD or CD.
In case 1, the stress of the coating near interface in TD was between 400 MPa and 800 MPa, as indicatedin Fig. 2 (a). However, the edge region showed a compress stress in TD in case 2, as shown in Fig. 2(d).
This result was ascribed to the larger thermal expansion coefficient of 304SS. During the cooling stage ofthe interface, the cooling shrinkage of 304SS near the interface was greatly larger than that of the coating.
Therefore, the coating was compressed by the substrate. However, the thermal expansion coefficients of
C45 (without MT) and the coating were close. A similar cooling shrinkage contributed to the tensile stressnear the interface. In case 1, the stress of the coating in CD was between 400 MPa and 800 MPa, as
indicated in Fig. 2 (c). In case 2, the stress of the coating in CD was between 0 MPa and 400 MPa (in Fig.

− 228 −

2(f)), which were lower than that in case 1. In addition, the stress of the edge region in CD was between-400 MPa and 0 MPa as shown in Fig. 2(f). The stress distribution of case 2 revealed that the larger
thermal expansion coefficient of the 304SS substrate relieved the stress of the coating. The
stress-temperature curves of the points in Fig. 3(a) are shown in Fig. 3(b)-(c). Point A represented theedge region. According to the stress evolution of Point A on the 304SS substrate, the stress in CD reachedapproximately 500 MPa at a temperature of approximately 620 °C. However, when the temperature
gradually declined, the stress in CD remarkably declined. Finally, the stress declined to 150 MPa when
the coating was cooled to room temperature.
The stress evolution of Point B on the C45 substrate in Fig. 3(a) is shown in Fig. 3(d). It was observedthat the MT of the substrate also resulted in a larger tensile stress in TD and CD. The stress in TD and CDreached approximately 560 MPa and 710 MPa, respectively. The larger stress of Point B in TD and CD
created a condition for crack propagation. Therefore, the initiated longitudinal and transverse cracks
propagated toward the surface of the coating.

Fig. 3 Stress evolution of the coating

Fig. 4 Schematic of longitudinal and transverses crack

3. Cracking mechanism
From a macro perspective, the MT of the HAZ of the C45 substrate was the key for cracking of the
FeCoNiCrAl coating. The MT contributed to the expansion of the substrate near the interface andenhanced the tensile stress of the coating. In addition, the MT improved the hardness of HAZ. The plastic
deformation ability of the HAZ of the C45 substrate was restricted. Therefore, the tensile stress in thecoating could not be relieved through the plastic deformation of the substrate.
For the longitudinal crack in Fig. 4(a), the edge of the coating on C45 had the maximum tensile stress(800 MPa-1200 MPa) in TD. This contributed to the crack initiation of every edge of the coating. During
the cladding of the next layer, the crack propagated only under a smaller tensile stress. Finally, a throughcrack was generated from the coating/substrate interface to the surface of the coating. In addition, thelongitudinal crack was continuous along the CD due to the inducing effect from the edge of every layer ofcoating. As the shift distance of every layer was 0.5 mm, the distance between two neighboring edges was
also 0.5 mm. Therefore, the distance between the long cracks was approximately 0.5 mm. For thetransverse crack, the coating had a maximum stress of 1000 MPa in CD. The high stress contributed to therandom cracking of the coating, as shown in Fig. 2 (a). When the next layer was cladded, the high tensilestress in CD resulted in crack propagation, as shown in Fig. 2 (b)-(d). The transverse crack is shown in Fig.
2 (e). During the cladding process, transverse cracks were generated after the formation of longitudinalcracks. The transverse crack was limited between two longitudinal cracks. Therefore, the transverse crack
was discontinuous.

Preliminary study of heat treatment effect on incremental formed sheet bythermal-elastic-plastic FEM
Hui Huang (Oak Ridge National Laboratory)
Ninshu Ma (JWRI, Osaka University)

Abstract
Incremental sheet forming (ISF) can be used to fabricate large-scale component with complex
geometry which is commonly seen in automotive body structures. The unwanted deformation due
to release of residual stresses in spring-back process will deteriorate the manufacturing accuracy
and require additional correction work. In order to reduce the produced stress in ISF, local line
heating is a good candidate method due to its high flexibility and efficiency. In the present study,
the mechanism of thermal distortion is investigated and the amount of stress reduction is quantified
numerically instead of trial-and-error procedure. In addition, the optimum heating temperature is
identified and effect of heating plan on residual stress and distortion were revealed throughnumerical simulation.

1. Model and Results
High-strength aluminum alloy AA6xxx sheet with dimension 800mmh650mmh1.1mm wasdesigned for numerical study. The incremental forming process was simulated by MSC-Dytran
software with shell element. The target depth of final geometry is 70mm as shown in Fig.(a), andthe four edges were clamped (fixed out-of-plane displacement) during processing. The deformed
geometry and solution variables such as stress and plastic strain were output as initial condition forheating analysis using Abaqus. The line heating pattern based on actual experimental condition was
employed to reduce residual stress caused by ISF. A 60 mm wide zone experienced the peaktemperature (~300ć), and a 90mm offset was defined for three heat paths, and temperature isassumed to be uniform distribution through thickness considering the sheet is thin and Al has highthermal conductivity. The simultaneous heating and moving heat source were compared and it was
found the simultaneous heating can reproduce the distortion behavior with sufficient accuracy whilesaving a lot of computational cost. It was also proved that buckling distortion will occur during suchheat treatment of thin sheet because the critical stress to trigger bucking is just several mega Pascal.
Therefore, large deformation theory must be used throughout the thermal-elastic-plastic analysis.
Fig.(b) shows the predicted heating distortion for each heating path. During heating, highcompressive stress will be produced in the plate, resulting in buckling distortion with a similartendency of the initial shape of the formed plate. The distortion magnitude firstly increases at thesecond heating path, which is due to the effect of accumulated compressive stress in the local region.
Then it decreases at the third heating because the heated region has large curvature and increased− 230 −

about 200 MPa. It can be understand that the stress produced by previous heating lines will begrossly relieved by the subsequent heating.
The heating temperature is an important factor during heat treatment of ISFed aluminum sheets.
In order to clarify the effect on residual stresses, the 100C, 200C and 300C peak heating temperature
were selected for the parametric study. By using 100C heating, the deformation is hardly reduced
because the impact on residual stress is limited. Fig. (d) shows the comparison of heating by 200C
and 300C. Residual stress is most reduced by heating at peak temperature 200C. On the other hand,plastic strain has non-observable change for all the cases.

2. Conclusions
The heating of Al thin sheets by ISF can reduce the residual stress significantly by introducing
a small additional distortion. The major outcome from this collaborative research work are as
follows:1) During heating, the downward buckling distortion will be produced which follows the same
bending direction of initial shape. After cooling, the distortion will reverse the direction due to thetensile stress produced by cooling.
2) Heating sequence and heat source moving style has insignificant impact on the final results which
can simply the modeling procedure and reduce computational cost.
3) The heating temperature at 200C was determined to be an optimum parameter considering theresultant effect on distortion and residual stresses.

Numerical analysis of welding deformation and residual stress: Submerged friction stir
welding of duplex stainless steel
Cao Fujun (Nanjing University of Aeronautics and Astronautics)
Ma Ninshu (JWRI, Osaka University)
Abstract
In this paper, submerged friction stir welding (SFSW), capable of significantly weakening thewelding thermal cycle compared to conventional FSW, was employed on SAF2507 super duplex
stainless steel (SDSS). An ultrafine grained (UFG) dual-phase microstructure, characterized bymore uniformly distributed and balanced alpha (Į) and gamma (Ȗ) phases with average grain sizesof 0.96 and 0.77ȝm, respectively, was achieved in the stir zone (SZ). Such unique microstructureleads to a synergistic enhancement of tensile strength and ductility in the longitudinal SZ at room
temperature, which increases from 840 MPa - 18 % under AFSW condition to 915 MPa - 22 %. In
addition, the relatively lower residual stress across the whole joint actually contributed to theincrement of ductility in the SFSW joint, as compared to the traditional FSW joint.
1. Materials and Methods
1.1 Materials and welding preparation
In the present work, commercial SAF2507 SDSS plates with length of 200 mm, width of 100 mm
and thickness of 4 mm, which contain 25.2Cr, 6.9Ni, 3.9Mo, 1.2Mn (wt.%) with balance Fe, wereused as the base material (BM). The FSW joints were prepared in air and water cooling conditions
with the same combination of rotation rate and welding speed (800 rpm-50 mm), respectively. The
tool angle of 2° and plunge depth of 0.2 mm for the whole shoulder were adopted. Fig. 1aillustrates the schematic view of SFSW with water cooling during welding. Prior to SFSW, theas-received workpieces with butt configuration were fixed on the backing plate in a plexiglass
container. Then, the sufficient water at room temperature was employed over the workpiecesurface by adjusting water flowing rate of inlet and outlet. A stirring tool made of W-Re was used,primarily comprising of a cylindrical shoulder with diameter of 12 mm and a conical pin taperedfrom 6 mm at the root to 4 mm at the tip. The pin length was 3.5 mm. In order to verify thecooling effect of the varying coolants on thermal cycle during FSW of SDSSs, a wirelesstemperature measurement system was applied to measure the SZ temperature in real time, using
K-type thermocouple with a diameter of 1 mm that was obliquely inserted into a thorough hole ofthe shoulder close to the SZ surface. The schematic diagram is presented in Fig. 1.

transverse direction and welding direction are defined as ND, TD and WD, respectively.

1.2 Residual stress testing
In order to investigate the surface residual stress of the resultant welds and the initial BM, theresidual stress examination was also conducted on the corresponding locations, using Proto LXRD
analyzer with Co-KĮ target at voltage and current of 30 kV and 25 mA, respectively.

software with coupled Eulerian-Lagrangian (CEL) model
was used to investigate the heat evolution anddeformation behavior during welding. The feasibility of
CEL formulation for friction stir welding has been
demonstrated in our previous studies by Ma and Geng
sensei. The corresponding CEL simulation model,
Lagrangial tool and Eulerian domain meshes is shown in
the right figure.
2. Conclusions
High-quality SFSW joints with UFG dual-phase microstructure were successfully processedin SAF 2507SDSSs. The microstructure changes and their effects on mechanical properties were
carefully investigated. The following summaries can be reached.
(1) In comparison to SFSW, SFSW with flowing water substantially decreased the welding peaktemperature from 1077.5 °C to 783.7 °C and the degree of surface oxidation, as well as the size of
SZ and TMAZ area, leading to a defect-free joint.
(2) It is well proved that SFSW effectively eliminated the unfavorable phase transformation
between Į and Ȗ, and simultaneously promoted the formation of more uniformly distributed UFG
dual-phase microstructure. A remarkable enhancement in YS and UTS of longitudinal SZ wasachieved from 840 to 915 MPa, from 997 to 1072 MPa, and El increased from 18 % to 22 %. As aresult, a more excellent strength-ductility trade-off for transverse SFSW joint combined with
reduced width of entire joint was obtained, exhibiting a slight improvement of YS, UTS and El.
(3) In addition to CDRX for Į and combination of CDRX and DDRX for Ȗ, the greatly inhibited
grain growth concurrently promoted the formation of UFG dual-phase microstructure and a higher
grain refinement efficiency in SFSW SZ.
(4) Grain boundary strengthening and dislocation strengthening in SFSW significantly contributed
to the increment of strength, and the higher ductility was dominated by the enhanced strain
hardening capacity, induced by uniformly distributed ultrafine microstructure comprising of Į andȖ phases and relatively lower residual stress, as well as reduced size of hard region including SZ
and TMAZ.

1.Introduction
Welding residual stress is generated by thermal stress caused by rapid heating and cooling locally in
welding by a welding heat source(Masubuchi 2013). The distribution and magnitude of residual welding
stress are affected by joint type, welding condition, restraint, etc. If the weld shape and welding
conditions are determined, the effect of restraint is very important. Restraints can be classified into
external and internal restraints, and internal restraints refer to restraints caused by temperature gradients
caused by welding heat. External restraint means restraint by welding sequence, weight and shape ofstructure. The residual stress generated in this way affects the fatigue strength, fracture strength, andbuckling strength (Woo et al. 2013). Therefore, since the magnitude and distribution of residual stressare very important in the safety evaluation of structures, guidelines for structural integrity evaluationsuggest a method of deriving welding residual stress. However, the welding residual stress presented in
the guideline (BS7910 2013; API579 2000; R6 1999) is in the state of no restraint. If there is a restraint,
the guideline (BS7910 2013) suggests using the yield stress of the base metal. In recent years, the useof high-strength steels with increased yield stress is increasing, and using the yield stress as the residual
stress at the time of restraint can be made with a very conservative design. Therefore, it is very important
to investigate the relationship between restraint and residual stress in welding and to predict the residual
stress according to the degree of restraint.
Liu Y. et al.(Liu et al. 2021) studied the external restraint effect to reduce the welding deformation
and residual stress of 304 stainless steel thin pipe. Experiments and analysis confirmed that the external
restraint device, which can move along with welding, is designed not only to restrain the structure but
also to dissipate the heat at the welded part, effectively reducing the deformation and residual stress ofthe thin-walled pipe. In addition, optimal constraint conditions were calculated through various
parametric analyses. Shin et al.(Shin, Lee, and Park 2010) investigated the relationship between the
maximum residual stress and the transverse stress as the degree of restraint increased in multi-layer
welding through experiments and analysis. As the degree of restraint in the transverse direction
increases, the effect on the maximum residual stress of the surface is small, and the average residual
stress increases proportionally as the degree of restraint in the transverse direction increases. However,in this study, only transverse restraint was considered, and residual stress was studied only on the surfaceof the specimen. Park et al.(Park et al. 2022) studied the effect and prediction of welding residual stressin the transverse direction according to the size of the transverse restraint. The reliability of the analysis
results was confirmed through experiments, and the analysis was conducted by changing the degree ofrestraint, thickness, and yield stress. In addition, the analysis results were analyzed with DNN (Deep− 234 −

Neural Network) to predict the residual stress according to the size of the transverse restraint. As
mentioned above, many studies have been conducted on the degree of restraint and residual stress in
welding, but it is difficult to find a study that considers both transverse and bending restraints at thesame time.
In this study, the effect of member thickness, yield stress, transverse restraint, and bending restraint
on welding residual stress in butt welding was investigated, and predictive factors for welding residual
stress were established. To this end, a thermal elastic-plastic analysis was performed by changing the
thickness, yield strength, transverse restraint, and bending restraint size of the member. Then, theanalysis results were learned with DNN (Deep Neural Network) to predict the residual stress at thecenter of the weld and toe. In addition, the influence of input factors that affect prediction accuracy
during DNN learning was considered.
2. Analysis modelling and DNN
In order to calculate the welding residual stress according to the constraint conditions, a thermal
elastic-plastic analysis was performed for a total of 72 analysis cases. The main variables are thethickness of the member, the yield strength, and the size of the transverse and bending constraint. The
member thickness was 25, 50, and 70 mm, the yield stress was 330, 405, and 590 MPa, and the restraint
condition was classified into transverse restraint and bending restraint, and four restraint sizes were set
for each thickness.
Figure 1 shows cross-section macros of thicknesses of 25, 50, and 70 mm used for thermal-elasticplastic analysis. The analysis was modeled from the cross-section of the welded part in Figure 1. The
number of welding passes and layers by thickness is 13 passes, 9 layers for a thickness of 25 mm, 34
passes, 11 layers for a thickness of 50 mm, and 60 passes, 21 layers for a thickness of 70 mm.

3. Conclusion
The effect of transverse restraint and bending restraint on residual welding stress in butt welding wasinvestigated, and the residual welding stress according to member thickness, yield strength, transverse
restraint and bending restraint was predicted through DNN analysis. To this end, thermal elastic-plastic
analysis was performed while varying the thickness, yield strength, transverse restraint, and bending
restraint of the member. And welding residual stress was predicted through DNN learning using theanalysis results. At this time, the prediction factors were changed to confirm the residual stressprediction accuracy according to the prediction factors.

Micro-patterning configuration by nanosecond laser ablation on the Al alloy surface:experimental observation and theoretical modeling
Suyu Wang (Jilin university)
Ningshu Ma (JWRI, Osaka university)
Abstract
Laser inducted heat and the ablation of materials are the key issues in material micronano precision processing and surface engineering. In this study, an FEM model wasdeveloped specifically for the laser ablation process for describing the dimensions of
micro-patterning and temperature distribution. The aim of this research is to provide a
visual simulation tool for key technical issues and analyze the influence of multiple
complex laser parameters on the temperature distribution. A good agreement between
experimental and model-predicted micro-patterning was observed, indicating high model
accuracy. Complementary studies that consider both experimental and thermal simulation
data at the same time are desirable to gain insight into micro-processing phenomena.
Keywords: Nanosecond laser ablation; element deletion; laser micro-patterning;temperature distribution
1. Materials and methods
1.1 laser ablation process
A 2 mm thick A6061 Al alloy (Al-1.2 wt% Mg-0.2 wt% Si) was used as basematerials. The laser ablation process was conducted via a nanosecond laser system (SP050 P-A-EP-Z-F-Y, SPI
Lasers), and the focusednanosecond laser beam wasscanned with a pulsed
width of 7 ns, frequency of
600 KHz, and laser beam
diameter of 40 ȝm. The
surface and cross-sectional
morphologies of processed
micro-patterning were observed,

as shown in Fig. 1.

1.2 Material model and heat source model
The laser ablation process on Al alloy surface was simulated using finite element
modeling method based on the commercial software Abaqus. The main physical issues in
the laser ablation process include thepulse laser motion and attenuation. The
model dimensions and meshingconditions are detailed for coarse meshand fine mesh, as presented in Fig. 2.
After a pulse is fired, the laser focus
position moves up relatively, which isequivalent to retracting a certain
distance. When the retracting distanceis close to the effective etching depth

depth tends to be stable.
2. Conclusion
A three-dimensional time-dependent simulation of pulsed laser ablation was
examined in the research. The main consideration was the heat effect of the incident laser
hence the simulation is based on the heat equation. The micro-patterning (groove structure)
was generated in the laser ablated area, and quantities of discrete micro/ nano particles
were formed around the heat-affected zone (HAZ) under the function of laser radiation
and recoil pressure. The ejected materials (Al alloy) were redeposited on the edges ofprocessed grooves to form teeth. The comparison images of different laser parameters arelisted, and a good agreement between experimental and model-predicted groove
dimensions was observed. When the laser power was low, there was a certain error in thecomparison between the experimental results and the simulation results owing to theoverflow of the molten metal was more extensive with a lower laser power, and it wasdifficult to predict the flow process. The groove dimension with high laser power
parameters was relatively stable, and the prediction performance is improved.

Pengkang Zhao (Xi’an University of Technology)
Ninshu Ma (JWRI, Osaka University)

Abstract:
In the paper, we discussed the effect of annealing on the microstructure, crystal texture, and toughness ofTi–6.5Al–3.5Mo–1.5Zr–0.3Si (TC11) and Ti–4Mo–4Cr–5Al–2Sn–2Zr (TC17) linear friction welding (LFW)
joint. The results reveal that the microstructure difference on both welded zone (WZ) decreases. The TC11 WZ
consists of supersaturated solid solution Įc phase and ȕ phase, the coarse Į grains disappear and theorthorhombic martensite Įcc phases transform into lamellar Į+Įc phases on the TC17 WZ after the double
furnace annealing. Two ȕ textures (shear and annealing textures) and two Į textures (D and E textures) exist at
the original joint, and both of them transform into new ȕ textures (brass and copper textures) and Į textures (Fand G textures) after the double furnace annealing. The dislocation density of the TC17 WZ is significantly
higher than that of the TC11 WZ at the original joint. After the double furnace annealing, dislocation density,
grain type, and Schmid factor (SF) distribute uniformly throughout the entire WZ. The average dislocation
density decreases slightly and the low SF ( P  0.25 ) almost disappears. The microhardness value of the entire
joint is more uniform and stable, and the fracture toughness is 137% higher than that of the original joint,
approximately reaching 91% of the TC11 fracture toughness. The research provides a theoretical basis for
preparing high-toughness joints of dissimilar titanium alloys.
1. Materials and experimental procedures
The TC11 BM consists of equiaxed Į and lamellar Įc+ȕ phases, and the TC17 BM presents a needle-likebasket structure and a high proportion of the ȕ phase. The ȕ phase is a body-centered cubic (BCC) structure andthe Į phase is a hexagonal close-packed (HCP) structure. The ȕ phase transforms into the Į phase when thetemperature decreases slowly. With the increase of cooling rate, the ȕ phase transforms into supersaturated solid
solution Į phase with low ȕ stable element and changes into a transitional orthorhombic martensite Į phasewith high ȕ stable element and transformation resistance. The phase transform temperature of TC11 (1000±20 °C)
is higher than that of TC17 (890±15 °C). The LFW experiment was completed at AVIC Manufacturing
Technology Institute in Beijing. The post-welded joint was annealed in three different ways in a resistancefurnace. The microstructure was observed by scanning electron microscopy (SEM), and the crystal texture wascharacterized by electron backscatter diffraction (EBSD). The phase composition on the WZ was identified by
the X-ray diffraction (XRD) method. The impact toughness and fracture toughness of the joints were tested. The
specimen’s length, width, and thickness are approximately 50 mm, 48 mm, and 20 mm, respectively. The crack
length of the sample is 17 mm.

2. Conclusions
This paper provides an optimization method to improve the toughness of the dissimilar titanium alloy joint
and discusses the microstructure and crystal texture evolution at the joint under annealing conditions. The main
conclusions are as follows:(1) After the double furnace annealing, the microstructure difference on both WZs decreases. TC11 WZ consistsof a supersaturated solid solution Įc phase and ȕ phase, the coarse Į grain disappears and the orthorhombic
martensite Įcc phase transforms into the lamellar Į+Įc phase distributed uniformly on the ȕ substrate on the
TC17 WZ.
(2) The texture density and dislocation density decrease, whereas the fractions of the high SF (ȝ>0.4) andsubstructured grains increase gradually after the double annealing. In addition, the proportion of grainboundaries near 60° and 90° are much higher than others, corresponding to the {1122} contraction twin and{10 12} extension twin, respectively.
(3) After the double furnace annealing, the microhardness on both sides of the joint is more uniform and stable,
and the impact toughness and fracture toughness are 203% and 137% higher than the original joint,respectively. In addition, there are numerous dimples on the propagation zone and shear lip zone,
corresponding to the typical ductile fracture mode.
