Alloy Design
Additive Manufacturing
Optimus Alloys is designing alloys to achieve "printability-performance" synergy as detailed in the article by Mishra and Thapliyal (2021) on aluminum alloys. The initial attempts are for laser powder bed fusion additive manufacturing. The approach itself is amenable to different fusion based additive manufacturing techniques. Find out more at "Design approaches for printability-performance synergy in Al alloys for laser-powder bed additive manufacturing"
Friction Stir Additive Deposition
Friction stir additive deposition is a solid state additive manufacturing technique. It is commercially known as the MELD process, patented by the MELD corporation. All the three processes discussed on this web site represent disruptive manufacturing technologies. Optimus Alloys brings detailed metallurgical knowledge to support and advance these new technologies or processes.
Friciton Stir Welding and Processing
Friction stir welding has revolutionized the solid state welding of high strength aluminum alloys. It has been widely adopted by industry. Have you ever wondered that for each new alloy, sheet/plate thickness, alloy temper, your industry has to do process development! Optimus Alloys can help you with its predictive approach. This will help you cut down on the experimental effort and improve joint performance. Check out the book on "Friction Stir Welding and Processing" by Mishra et al. 2014.
Examples
Aluminum Alloys
Aluminum alloys provide the best opportunities for lightweight structures with or without topological optimization. Optimus Alloys is working on new alloy compositions that allow microstructural control and printability over a wide range of process parameters. See the article (Design of heterogeneous structured Al alloys with wide processing window for laser-powder bed fusion additive manufacturing) by Thapliyal et al. (2021) as an example of such an approach.
Copper Alloys
Copper alloys provide best opportunities for high performance conductors. Optimus Alloys is designing copper alloys with combination of high conductivity and strength for heat exchangers and other thermal management applications.
High Entropy Alloys
High entropy alloys are changing the paradigm of metallic alloys. Optimus Alloys is designing alloys that exhibit superior combination of properties and take advantage of hierarchical deformation mechanisms. Check out the fundamentals and potential of these alloys for enhanced mechanical properties in this overview article "High entropy alloys – Tunability of deformation mechanisms through integration of compositional and microstructural domains" by Mishra et al. (2021).
