Phase transformations in metals during welding can be influenced by changes in temperature, pressure, or composition. By effectively modeling these behaviors, design engineers can enhance material selection and optimize joining processes throughout product development. Learn how EWI uses analytical equations to predict phase transformations in this new paper authored by Dr. Alber Sadek, Rafael Giorjao, and Jerry Gould. https://lnkd.in/grte7-SA #EWI #ICME #MaterialsScience #WeldingEngineering #PhaseTransformations #ResearchPublication

It was a great experience to discuss our first insights and the overall project idea of the DILAPRO Project at MAMC. I am convinced that DILAPRO has the potential to decrease the environment impact of additive manufacturing, by e.g. reducing the need for certification coupons printed in each build.

++New publication in the magazine Welding in the World++ In the frame of the research project We3D, funded by FFG Österreichische Forschungsförderungsgesellschaft mbH Authors: Matthias Moschinger (IMAT), Thomas Vauderwange (VauQuadrat GmbH), Norbert Enzinger (IMAT) title: Plasma wire arc additive manufacturing and its influence on high-carbon steel substrate properties https://lnkd.in/dFTjmqak In this study, a high-strength multilayer structure on a high-carbon steel substrate was manufactured and investigated. The tempering effects caused by additive manufacturing (AM) were demonstrated Layer by Layer. In addition, local preheating using Penetration Depth Induction (PDI) was performed. The idea of energy rearrangement by PDI was also tried. This study shows the challenges but also the possibilities of AM on high-carbon steels without extensive heat treatment.

I'm happy to share my first paper publication on "Experimental Investigation of Al-6061 Metal Matrix Composite Reinforced with Selenium" in the MATEC Web of Conferences. This paper explores the influence of selenium particles in Al-6061.Metal matrix composite material was prepared with Al-6061 reinforced with selenium by using stir casting. A total of 3 samples were fabricated based on the wt% of selenium. Various tests regarding the material's mechanical properties are performed on these samples to analyze the trend of the properties with the increase in wt% of selenium and to conclude which one is the best among all. #composites #Al6061

#NCAME is currently performing a comprehensive study, funded by National Institute of Standards and Technology (NIST), on #NDE-based #qualification and the probability of detection (#PoD) of AM-induced defects. Several alloys, such as AlSi10Mg, Scalmalloy, Ti-6Al-4V, and Inconel 718 are being investigated as part of this effort. This work attempts to understand the influence of various #XCT acquisition parameters and the size of the part on the PoD of #defects. Supported by experimental fatigue data and defect #criticality studies, the results of this work will strive to accelerate the adoption of the #AM into industry through multiple ASTM International standardization efforts.

ASC is collaborating with Australia’s national science agency, CSIRO, and DMTC Limited, to pioneer the use of additive manufacturing for the repair of Collins Class submarines. Cold spray is an additive manufacturing and repair method that uses a stream of supersonic gas to accelerate metal powder particles at a surface, building up a dense deposit. Successful development of the cold spray technique for this specific maritime application will allow Australian submarines to remain at sea for longer, without the need to dock for lengthy repairs.

As the ARC Training Centre for Surface Engineering of Advanced Materials (SEAM_ARC) concludes its 5-year journey of industrial research collaborations, the impact of its work is becoming clear. The September issue of Materials Australia magazine highlights three standout projects. We are proud to have been an industrial partner in two of them.

His findings enable LaserBond to deliver claddings and AM structures with enhanced quality and performance to our customers. Alexander Osi led the design and testing of a lightweight hydraulic piston rod, featuring a HVOF WC-NiCr coating, reducing overall weight by an impressive 63%. This project was conducted in partnership with MacTaggart Scott and DMTC Ltd. Ryan Yeates from MacTaggart Scott notes that this project has created “not just a theory but a piece of hardware we can take to industry”. #AdditiveManufacturing #thermalspraying #lasermetaldeposition #HVOF #DED #surfaceengineering #industrialresearch #defence

Introducing Paul Poulain, one of our Phd students here at the Welding and Additive Manufacturing Centre (WAMC), who recently presented at the SFF Conference, Austin, TX, USA. The Annual International Solid Freeform Fabrication Symposium (SFF) is a conference dedicated to Additive Manufacturing. It features technical sessions, paper presentations, and award ceremonies, offering a space for researchers and industry experts to share insights and explore recent developments in the additive manufacturing field. Check out Paul's abstract here "Super Duplex Stainless Steels (SDSS) manufactured by Wire Direct Energy Deposition (WDED) often exhibit typical coarse columnar grain structures and undesirable phase balance, which is detrimental to mechanical performance and corrosion resistance. In this investigation, in-process mechanical works, including High-Pressure Rolling (HPR) and Machine Hammer Peening (MHP), were applied during the WDED process of SDSS to evaluate their influence on the microstructure and mechanical performance. Three single-pass walls were deposited using plasma transferred arc WDED process with different in-process conditions: no in-process deformation (as the control group); HPR with an average force of 75 kN; in-process MHP with a frequency of 36 Hz and energy per impact of 6 J. In-process mechanical work helps the transition from coarse columnar to fine equiaxed ferrite grains and also promote formation of austenite. These findings demonstrate the benefits of in-process mechanical work in the WDED process of SDSS".
