| Abstract Scope |
Refractory alloys are candidate materials for future high temperature aerospace applications, since many of these new environments exceed the temperature limits of state-of-the-art nickel superalloys. However, some of the strongest refractory alloys have been historically challenging to process through conventional wrought techniques. Reconsideration of powder metallurgy methodologies and advancements in near net shape manufacturing have expanded the processing potential and viability for implementing novel refractory alloy components. These processing enhancements lower the barrier to mechanically assessing novel refractory alloys in both cast and microstructurally relevant conditions. This concept will be discussed in relation to known high temperature strengthening mechanisms in refractory alloys. In addition, key microstructural and chemical phenomena predicted to influence mechanical performance at various length scales will be addressed. |
