| Abstract Scope |
Understanding structure-processing-property-performance relationships of metallic alloys is critical to their manufacture and performance in extreme environments. Significant opportunities exist to not only employ conventional manufacturing processes like thermomechanical processing, but also advanced manufacturing processes like additive manufacturing that impart unique microstructural characteristics (defect substructures, metastable phases, grain sizes and morphologies, textures, etc.) at varying length scales that impact mechanical properties and performance. Recent examples of metallic alloy microstructures produced under additive manufacturing conditions and thermomechanical processing to link processing conditions to microstructural development are highlighted. Selected examples of microstructural response with testing under different deformation conditions (e.g., strain rates up to 103 s-1) are also highlighted. Such studies will yield novel alloying, processing, and microstructural and property design strategies to achieve advanced manufacturing of metallic alloys and performance in extreme environments. |
