High Mixing Entropy Alloys Design with High Anticorrosion and Wear-Resistance Properties

Abstract

High entropy alloys emerge as a new type of advanced metallic materials, which have received increasing attentions from material engineers around the world. In addition to high entropy effect based on equiatomic or near-equiatomic and containing five or more principal elements, they exhibit a cocktail effect resulting from interactions among all the elements and the indirect effects of the various elements on the performances. In this study, according to high entropy alloy design principles, corrosion-resistant elements such as Al, Ni, Cr and Mo were used to improve the anticorrosion property, Fe, Co, B and Si as solid solution elements were added to promote the formation of solid solutions with simple structure, and the wear-resisting property increased.
