Abstract

The microstructure, hardening behavior, and adhesive wear behavior of Al0.3CrFe1.5MnNi0.5 high-entropy alloys were investigated. All alloys exhibit superior adhesive wear resistance to cast iron FC-300, bearing steel SUJ-2, and hot-mold steel SKD-61. The superior wear resistance of the alloys is attributable to the formation of ρ phase during the furnace cooling from the homogenization at 1100 °C or the in situ formation of the ρphase induced by the high interface temperature and severe plastic deformation during wear sliding.
