| Abstract Scope |
Understanding structure-processing-property-performance relationships of metallic alloys is critical to their manufacture and use in extreme environments. For example, refractory multi-principal element alloys (RMPEAs) are affording new opportunities for high temperature performance in aerospace, defense, and energy applications. Significant opportunity exists to not only employ emerging manufacturing technologies like additive manufacturing to make refractory alloys, but also conventional manufacturing processes like deformation processing to tailor microstructures. Here we highlight recent efforts to link materials processing to refractory alloy microstructure development, including aspects like dynamic recrystallization in RMPEAs produced by thermomechanical processing. Such studies will yield novel alloying, processing, and microstructural and property design strategies to achieve advanced manufacturing of refractory alloys and performance in extreme environments. |
