| Abstract Scope |
Refractory alloys are promising materials for high-temperature applications because of their high strength at elevated temperatures, high thermal conductivity, and low thermal expansion. Despite these attractive properties, most refractory alloys exhibit poor ductility at room temperature, making processing via traditional methods difficult. Establishing thermo-mechanical processing procedures for refractory alloys is key for investigating their mechanical properties and enabling the adaptation and commercialization of new-generation refractory alloys. A ternary, equiatomic NbTaV alloy is synthesized via vacuum arc melting and thermo-mechanically processed via hot forging at 1200°C followed by cold rolling at room temperature. The high-temperature tensile behavior of the thermo-mechanically processed materials are evaluated at 1300°C, and the effects of different processing routes on the grain size, microstructure, and elemental segregation are investigated. |
