​Abstract
High-entropy alloys (HEAs), or multi-principal-element alloys, are now at the research frontier of advanced metallic materials. They differ from previously known multi-element alloys in that there is not any principal or dominant alloying element in them, as in the case of steels where iron is the principal element. The alloying concept of high-entropy alloys brings in an unprecedented opportunity to explore the vast compositional space that was previously untouched. Refractory high-entropy alloys (RHEAs), an important category of HEAs which comprise mainly refractory (i.e., high melting points) elements, emerge as promising candidate materials for ultrahigh-temperature applications. One critical issue to solve for RHEAs is to achieve balanced oxidation resistance and mechanical properties, mainly room-temperature ductility for the latter. In this talk, I will present some of our recent efforts addressing to this challenge, and my personal vision of the future prospect regarding developing RHEAs as potential ultrahigh-temperature materials.
