Low Temperature Sintering Of WC Based Diamond Enhanced Cemented Carbides With Novel Co-free Binder Systems
Authors: von Spalden Mathias , Pötschke Johannes , Rosiński Marcin
Published: November 2024

In this work, Co-free WC based diamond enhanced cemented carbides (DECC) have been prepared and studied. Two approaches regarding the manufacturing process and metallic binder system were applied to minimize degradation of the metastable diamond into graphite. Two types of field assisted sintering techniques (FAST) were used, which allows consolidation of powders at lower temperatures within a much shorter dwell time compared to conventional sintering techniques. Binder systems were optimised to achieve a further decrease in sintering temperatures while maintaining a fully dense composite. Instead of Co, which is rated as toxic and a critical raw material, Fe, Ni and an in-situ formed alloy from Ni and Cu were used as metallic binder materials. These novel composites are compared to conventional Co-based DECC by means of microstructural and mechanical properties. SEM observations revealed that less diamond is degraded into graphite with the use of the studied novel binder systems.

Authors: Cabrol Elodie , Si-Mohand Hocine , Missemer Florent , Deborde Agathe , Delfosse Jérôme , Sasaki Layla
Published: November 2024

In this work, we have investigated the influence of the presence of satellites on the flowability properties of a TA6V powder. Thermal plasma treatments have been performed to spheroidize the powder at various feed rates (2 to 8 kg|h) under Ar|He atmosphere. The physical and chemical properties of the initial and treated powders have been characterized: morphology, particle size distribution, flow rate, apparent and tap densities, interstitial contents (oxygen, nitrogen and hydrogen). The results have shown that the best powder produced by plasma treatment was spherical, satellites-free and without noticeable effect on the particle size distribution. The Ar|He atmosphere leads to very low interstitial contamination. In addition, an improvement in flow rate of 30% was observed as well as an increase in apparent and tap densities of 20% and 8% respectively.

Authors: Upadhyaya Prathviraj , M. Uí Mhurchadha Sinéad , J. McCarthy Oliver , Kennedy Tríona , Raghavendra Ramesh
Published: November 2024

WE43 magnesium alloy is a low density, biocompatible material that has been identified as a viable option for temporary orthopaedic implants due to its favourable mechanical and biodegradation properties. This bioresorbable material eliminates the requirement for an invasive second surgery to remove a traditional bioinert temporary implant after the bone has regenerated. Additive manufacturing allows for complex structures with biomimicry features to be produced. However, the additive manufacturing of Magnesium and its alloys is not a trivial task due to challenges associated with the processability of Magnesium. This paper presents a methodology to additively manufacture WE43 components. Furthermore, an additively manufactured demonstrator orthopaedic fixture is presented and the microstructure evolved within the part and the resulting mechanical and corrosion properties are characterised. This research is aimed towards the development of additively manufactured, bioresorbable orthopaedic implants, with potential to improve clinical outcomes for patients.

Authors: Levano Blanch Oliver , Fernandez Silva Beatriz , Lister Samuel , Jackson Martin
Published: November 2024

Titanium alloys are well known for their high strength to weight ratio. However, its use is restricted in many sectors simply due to its high cost when processed through the conventional route. Powder metallurgy has been proven as an alternative way to reduce the cost of near-net shape titanium components. The cost of powder is related to its source, but technologies like additive manufacturing (AM) produce large quantities of surplus powder that can be reused with alternative technologies. Alternatively, the option to use titanium machining swarf as a feedstock material is also explored to further reduce the price of titanium components.In this work, Ti-6Al-4V swarf and surplus AM powder has been consolidated using field-assisted sintering technology (FAST) and hot isostatic pressing (HIP). The consolidation, microstructure and hardness has been assessed to explore and compare the potential of these technologies in the production of low-cost titanium near-net shape parts.
Constitutive Modelling Of Solid State Sintering Of Cemented Carbides
Authors: Rosenblad Louise , Larsson Per-Lennart , Staf Hjalmar , Larsson Henrik
Published: November 2024

From a previously developed constitutive model of cemented carbide, the powder size- and configuration can be used to simulate the densification during the sintering process. However, small differences in experimental execution cannot be accounted for in the simulation, making the model sensitive. Here, we study how well the developed constitutive model can capture the experimental results of a dilatometer test. Three different experiments were performed where the only difference was the transition between the debinding and sintering process. From parameter adjustments, it is seen that the constitutive model is more suited to a certain experimental setup, which is a limitation of the model.

Authors: Gobber Federico Simone , Actis Grande Marco
Published: November 2024

Duplex stainless steels represent a very promising alternative when aggressive|marine atmospheres characterize the component’s final application. In this frame, grades with higher Pitting Resistance Equivalent Number (40 or above) may be used in hydrogen sulphide and chloride-containing environments. UNS 32760 Duplex Stainless Steel powders have been obtained by means of close coupled gas atomization, starting from wrought bars. The paper analyses the effect of different parameters on the characteristics of the final powder, in terms of granulometry, orphology, microstructure, and chemical composition (compared to the starting material), also taking into account light elements as N, O, H, C, and S.

Authors: Lores Asier , Lagos Miguel Angel , Leizaola Iñaki , Agote Iñigo , Bringer Charlotte , Neubauer Erich , Kovacova Zuzana , Wallis Christopher
Published: November 2024

Electronic packages and sensors for special purpose applications demands the use of high electrical resistivity ceramics and conductive metallic materials which are sometimes difficult to be compatibilized, and whose manufacturing process involves many different processing steps. In this study, a bi-material composite consisting on a resistive SiC-Feldspar ceramic with around 109O.cm and a conductive Invar36 alloy has been developed in a one-step process by Spark Plasma Sintering (SPS). The SPS process permits the fast co-sintering of the composite achieving near full densities. Also, it has been observed that the joining interface of the material is stable and crack free. Both selected ceramic and metallic materials have low and similar CTE values (3.5 ppm|K), which makes them ideal for co-processing purposes and also for applications where high dimensional stability is required.
Influence Of Densification And Case Hardening On The NVH Behavior Of Sintered Gears
Authors: Scholzen Philipp , Brimmers Jens , Brecher Christian
Published: November 2024

The powder metallurgical manufacturing of gears offers a promising opportunity in terms of reducing the noise emission and increasing the power density. Sintered gears weigh less than conventional gears and potentially have a better noise-vibration-harshness behavior, due to the remaining porosity. However, the potential of sintered gears for highly loaded applications is not fully utilized yet. Six variants of surface densified and case-hardened sintered gears from Astaloy Mo85 were tested to analyze the impact of the densification and case hardening depths on both the tooth root and flank load bearing capacities. A densification of the tooth flanks during operation was identified. The results were presented at EuroPM2021. Now, further analyses are carried out on the stress distribution in the densified tooth. Furthermore, the influence of the deformation during operation on the NVH behavior is investigated by means of transmission error and structure borne noise emission.
High-frequency Screening Of Metal Powder
Authors: Middelhof Thorsten , Huhn Vito
Published: November 2024

The increasing scarcity of resources requires sustainable management of raw materials at all levels. Additive manufacturing is a process that conserves raw materials and offers further potential for saving raw materials such as metallic powder. In addition to the manufactured end product, residual powder in the form of agglomerated or dust remains. In order to achieve the desired quality of the metal powder, all impurities, undersized particles and dust need to be removed and agglomerates have to be loosened. This can be achieved in a screening machine that is tailored to the needs of the specific metal powder in order to maintain a high quality. The machine needs to be gas-tight for an inert gas atmosphere, shall be easy to access and clean and sieve the metal accurately at high throughputs. This paper presents the parameters such as different frequencies that have an impact on the screening efficiency.

This paper aims to investigate the influence of the process gas atmosphere during the Powder Bed Fusion of Metals using a Laser Beam (PBF-LB|M) of a Nickel-Chromium alloy on the melt pool geometries of single laser tracks and on the discoloration of process by-products. The trials were performed on an EOS M290, which was equipped with a photodiode-based melt pool monitoring system (MPM). First results indicated differences in the intensity levels of the MPM signal and in the penetration depths. Furthermore, a correlation between the discoloration of the sampled powder material and the intensity level of the MPM signal was detected.
Investigation Into Effects Of Thermal Treatments On High Temperature Mechanical Properties Of Ti-48Al-2Cr-2Nb Alloy Produced By Electron Beam Melting Method
Authors: Bilgin Guney Mert , Kutlu Zuhal , Orhangul Akin
Published: November 2024

High strength and improved elevated temperature properties along with their low density make ?-TiAl alloys attractive for aircraft engines. In this study, Ti-48Al-2Cr-2Nb samples were produced by electron beam melting (EBM) method. As-built EBM ?-TiAl mechanical properties significantly differ from those of the parts produced by conventional methods due to several issues including microstructural instabilities, porosity and residual stresses. Therefore, a subsequent heat treatment was found to be vital to eliminate those issues generated from the nature of the EBM layered process. The Ti-48Al-2Cr-2Nb alloy typically contains two main phases, ?-TiAl as the matrix and a2-Ti3Al with various morphologies depending on the type of the processing and heat treatment history. The present study was conducted to characterize the microstructure, high temperature tensile strength behavior of EBM manufactured Ti-48Al-2Cr-2Nb samples in the as-built, HIP’ed and heat-treated conditions within the purpose of utilizing this alloy for structural aerospace applications.

Authors: Nakamura Koji , Ando Isshin , Hirayama Kyosuke , Aramaki Masatoshi , Jiang Fei , Tsuji Takeshi , Ashizuka Kosuke , Uesugi Masayuki , Takeuchi Akihisa , Ozaki Yukiko
Published: November 2024

For a high-density pure iron sintered compact without open pores, the 3D pore configurations at different strain levels during ductility tests were visualized by X-ray computed tomography (CT). In addition, each three-dimensional structure was quantified as a two-dimensional scatter plot, persistent diagram, by 1st persistent homology (PH) analysis. By comparing the scatter plots, specific local pore configurations sensitive to changes in strain were extracted. The results showed that, just prior to fracture, adjacent closed pores formed pore-clusters and coalesce to each other into larger pores. This process is consistent with the theory of ductile fracture of the void model proposed for wrought metals.

Published: November 2024

Advents in additive technologies have enabled the production of tailormade prostheses for medical applications. This achievement is limited by the yet scarce available commercial materials. This work explores the use of fused filament fabrication for the production of a bone prosthesis of biocompatible CoCrMo alloy. One of the biggest challenges was the design of a highly loaded feedstock capable be turned into a coiling filament adapted to the FFF requirements. A suitable filament was successfully created and printing conditions optimized. A thorough study was carried out to determine debinding and sintering conditions, with particular focus on the dimensional precision, microstructure analysis and hardness test. Finally, the filament was tested for the processing of an acetabular shell for a hip prosthesis with dense|porous zones.
Physical Properties Of Sintered Steels: Effect Of Porosity On Young's Modulus, Damping And Electrical Conductivity
Authors: Gierl-Mayer Christian , Danninger Herbert
Published: November 2024

Almost all properties of sintered steels depend on porosity. Although electrical conductivity and also Young’s modulus are important physical properties, not many data about sintered steels have been published. This paper extends the database for sintered steels, which was already started with thermophysical properties. It is shown that the electrical conductivity depends not only on the density but also on the sintering intensity and the composition, while Young’s modulus is only dependent on the density. All of the data are compared to the previous measurements done with the same material, but in different batches.
A Round Robin Test To Investigate The Printing Quality Of PBF-LB|M Processed AlSi10Mg
Authors: Schneider Markus , Schlingmann Tina , Schmidt Jonathan , Bettge Dirk , Hilgenberg Kai , Binder Maximilian , Klöden Burghardt
Published: November 2024

When it comes to higher accuracies, new technologies and real applications in additive manufacturing, there is one topic which cannot be avoided: The material response on the chosen processing parameters and its agreement and correspondence with literature data of the wrought material grade counterpart. In industrial additive manufacturing standards in terms of printing parameters, protection gas atmospheres or powder handling instructions are not obligatory. Therefore, the question must be answered whether the additive manufacturing process is reproducible and reliable over different printing companies. This was the motivation to realize a round robin test between 8 European printing companies and academic partners. The consortium had printed and tested fatigue and tensile testing bars under plant-specific conditions. A commonly used cast aluminum alloy, AlSi10Mg, was chosen as test material for the PBF-LB|M process. Differences of the results between the partners and the scatter itself were discussed in detail.

Authors: Mehta Bharat , Bengtsson Sven , Nyborg Lars , Frisk Karin
Published: November 2024

The powder bed fusion – laser beam (PBF-LB) process can produce parts with complex geometry. Light weight designs can be created and by using light alloys further weight savings can be achieved. However, minimizing printing defects using standard aluminium alloys, such as 2000, 6000 and 7000 series alloys, have proved to be difficult since they are all prone to solidification cracking. In the present study, two aluminium alloys are addressed: The first alloy is the AlSi10Mg alloy known for easy printing and consistent quality in PBF-LB printing process. The second material is a novel alloy from self-developed Al-Mn-Cr-Zr family of alloys designed to inherently resist solidification cracking, while also providing strong ageing response. The quality of printing and resulting mechanical properties are compared. The results show that the new material prints in a robust way and that the mechanical properties are superior to those of AlSi10Mg.

Revealing the phonon properties for thermoelectric materials by neutron scattering
Authors: Zhu Jinfeng , Shen Xiaoling , Ding Jingxuan , Ma Jie
Published: November 2024

Thermoelectric (TE) materials are widely investigated for their ability to directly interconvert electrical and thermal energy, with applications in waste-heat recovery, renewable energy and energy storage. As a quantum many-body problem in strongly correlated systems, exploring the elementary excitations and the complex couplings is crucial for designing and optimizing efficient energy-conversion materials. For TE materials, electronic manipulation and thermal transport engineering are two effective strategies for enhancing heat-to-electricity conversion efficiency. The lattice thermal conductivity, κlat, is the only independent parameter for optimizing the TE performance and attracts the interest of both theorists and experimentalists. Phonon engineering is essential to effectively manage lattice thermal transport. Recent progress in theoretical models and experimental techniques enables us not only to directly simulate and capture the phonon properties but also to establish clear physical pictures of phonon engineering to understand these advanced functional TE materials. An overview of employing the neutron scattering technique to investigate phonon engineering is introduced.

La Fin Justifie-t-elle Les Moyens? La Justice dans LES JUSTES D'Albert Camus.
Authors: Annan-Edufful Daniel
Published: November 2024

The correlation between Ends and Means has remained controversial from time immemorial. To date, whether ends justify means and vice versa have never become a settled issue. This makes the topic we are investigating today very important in the field particularly of Justice and generally of the Social Sciences and Humanities. Should some people continue to think that the achievement of their endeavor matters no matter the methods adopted or the latter must be genuine at all costs? Is it in appropriate to reject personal suicide and accept to murder somebody? Again, to what extent could one consider an action as a necessary evil? Our investigation thus aims to test the assumptions by seeking to determine what is supposed to receive focus in every human endeavor with regard to ends and means. In the light of this, our focus is on Justice from the viewpoint of a decision to kill a dictatorial king with children so as to manifest freedom and happiness. At the end of it all, that the success of the day should not be judged by the evening harvest other than the grains sewn becomes the key message and a summary of major findings. This contributes to the field (especially vis-à-vis ethics) in as much as it reinforces focus on the means – which reflects existing table of values, law and equity – in every human effort.

Balance is acknowledged as a vital component of a human when doing various everyday tasks. An imbalance increases the risk of falling or getting hurt, which lowers the quality of life. The balance has two distinct types: static balance and dynamic balance. The aim of this study was to determine whether there is association or not between static and dynamic balance among undergraduate students of Allied Health Sciences of Sarhad University of Science and Information Technology Peshawar, Pakistan. An analytical cross-sectional study was conducted on 317 healthy participants using convenience sampling. A single leg stance test with eyes closed and eyes opened was used for static balance, and Y balance test was used for dynamic balance. Pearson Correlation was used to find relation static and dynamic balance. SPSS software version 20 was used in this study. The analysis revealed a correlation between static and dynamic balance (r=0.09), indicating a weakly positive relationship between the two dimensions. This cross-sectional study provides a comprehensive understanding of the static and dynamic balance skills in health sciences students. The findings may guide the development of targeted interventions to improve students’ balance and general physical abilities.

Objective: The purpose of this study was to investigate the effect of continuous aerobic and high-intensity interval training on some physical fitness factors in young football players. Methods and Materials: For this purpose, 45 young football players from Hamadan were randomly selected and divided into three groups of 15: the continuous high-intensity aerobic training group (three sessions per week, at 90-95% of maximum heart rate), the high-intensity interval training group (three days per week, 30 minutes of high-intensity training, 30 minutes of rest), and the control group. At the beginning and after the completion of the 6-week training protocol, factors such as sprint speed test, 4x9 shuttle run agility test, and explosive leg power test were measured. The collected data were then analyzed using covariance analysis (ANCOVA) with pre-test values as the covariate and pairwise comparisons using Bonferroni post hoc test in SPSS version 26, with a significance level of less than 0.05. Findings: The results showed significant differences in all physical fitness factors among all groups compared to the control group and among the groups themselves. Conclusion: The results of this study suggest that both continuous high-intensity aerobic training and high-intensity interval training likely lead to significant improvements in physical fitness factors, with continuous aerobic training potentially resulting in greater improvements. However, further research is needed for more precise examination.
