| Abstract Scope |
A Materials Design Simulator (MDS) – based on coupling a CALPHAD thermodynamic software with a global constrained search engine – will be presented to discover new Titanium-X (X = Nb, Sn, Ta, Ti, Zr) alloys with optimal composition for microstructural control during additive manufacturing. Results for complex multi-component alloys will be presented with an emphasis on the columnar to equiaxed transition (CET). A new alloy designed using our MDS will be presented with experimental characterizations confirming the CET. The presentation will conclude with the prospect of additional developments for improving the efficiency of the search for high-performance materials for AM.
