| Abstract Scope |
Refractory high-entropy alloys (RHEAs) are promising materials that could be used as structural materials in advanced nuclear reactors because of their high oxidation resistance, thermal stability, and wear resistance. However, their brittleness, underscored by the high ductile-to-brittle transition temperatures, limits their ease of fabrication. In this talk, we will discuss a combined density functional theory with machine learning techniques to design RHEAs with promising high temperature ductility and radiation resistance. The predicted alloy compositions were experimentally verified. In agreement with the computational screening, many of these alloys have high temperature ductility and are easy to fabricate without cracking. The approach used here could aid the rapid design of new alloy compositions with targeted properties. |
