 This research paper examines the properties of a novel type of alloy known as a refractory high entropy alloy, RHEA. This alloy was designed to withstand harsh environments such as those found in nuclear power plants or in outer space. Through experiments and simulations, it was discovered that this alloy has excellent thermal stability and radiation resistance. It also showed minimal defect generation and no detectable grain growth when exposed to dual beam irradiation or helium implantation. These findings suggest that rears could be used in future applications where extreme environments are present. This article was authored by O.L. Atwani, H.T.V.O., M.A. Tunes, and others.
