This program will define opportunities for mechanical property optimization of metallic alloys used in hypersonic vehicles. ICME models that accurately predict the performance of new metallic alloys and ceramic/CMC materials will be created. Manufacturing supply chain(s) for new metallic alloy powders will be established. The mechanical properties predicted through ICME models will be correlated through real-world testing. Disparate metallic alloys will be joined through solid-state joining techniques. The materials database will be augmented with performance results of new alloys and Ceramic/CMC’s.
