| Abstract Scope |
Refractory metals and their alloys are important structural materials for elevated temperature environments. Despite extensive research during the mid-20th century, challenges in achieving a balanced set of properties, including fabricability and oxidation resistance, hindered the broad implementation of this alloy class. Recently, modern interest in these materials has been renewed by the refractory multi-principal element alloy (RMPEA) design philosophy and new processing pathways, such as additive manufacturing (AM), that enable their production. This presentation provides a critical comparison of the historical and modern approaches to refractory alloy design, examined through the lens of Nb-based alloys, and highlights overlaps between conventional refractory alloys and RMPEAs. Key areas discussed include conventional design rules for Nb-based alloys; the importance of processing in the successful adoption of new materials; and insights for designing alloys for AM that are derived from the welding literature. Knowledge gaps and opportunities to address them are identified. |
