The goal of this opportunity is fundamental and applied metallic, intermetallic and metallic-based composite materials research to improve performance, increase operating temperatures, and lower component costs for aircraft and space-propulsion systems. Research for these systems is being conducted on shape-memory alloys, soft magnetic alloys, copper-based alloys, and superalloys. Theoretical and experimental studies will provide a basic understanding and laboratory-scale materials development will lead to improved materials for use by US industry. For structural alloys, the processing-microstructure-property relationships inform high-temperature failure mechanisms and lead to life-prediction methods including complex creep-fatigue-environment damage interactions. Research techniques consist of computational methods, dislocation theory, and solid-state alloy theory; analytical methods including scanning and transmission electron microscopy, analytical chemistry, magnetic characterization, and x-ray diffraction; mechanical testing including tension, creep, and fatigue; and processing methods including alloy development, additive manufacturing, casting, powder metallurgy, and joining.
