The effects of irradiation on CrMnFeCoNi high-entropy alloy and its derivatives

High-entropy alloys (HEAs), based on equiatomic or near-equiatomic mixture of usually four more elements, have attracted considerable attention as there are indications that along with surprising microstructural simplicity some alloys, they may also offer intriguing combinations mechanical and other properties. Amongst these properties, is growing interest in the irradiation response HEAs their potential to withstand neutron bombardment environment future civil nuclear power plants. One first proposed face-centred cubic CrMnFeCoNi, known Cantor alloy, alloy its sub-systems focus this review. Using analogues (electrons, heavy ions He) considering simulations, advanced analysis property measurement, derivatives shown exhibit encouraging resistance that, many instances, superior traditional dilute same elements. The beneficial aspects high phase stability radiation-induced segregation, smaller size but higher number density dislocation loops, significantly lower extent swelling improved He bubble growth. research directions for resistant suggested.
