Radiation-tolerant high-entropy alloys via interstitial-solute-induced chemical heterogeneities
High-entropy alloys (HEAs) composed of multiple principal elements have been shown to
offer improved radiation resistance over their elemental or dilute-solution counterparts.
Using NiCoFeCrMn HEA as a model, here we introduce carbon and nitrogen interstitial
alloying elements to impart chemical heterogeneities in the form of the local chemical order
(LCO) and associated compositional variations. Density functional theory simulations predict
chemical short-range order (CSRO)(nearest neighbors and the next couple of atomic shells) …
