Wear and oxidation resistances of AlCrFeNiTi-based high entropy alloys

Based on the AlCoCrFeNi high entropy alloy, by replacing Co with Ti, new cobalt-free high entropy alloys AlCrFeNiTi and its derivative AlCrFeNiTiMn0.5 were designed and prepared by arc melting, and as-cast microstructures, wear and oxidation behaviors were investigated. The results show that two alloys are all composed of an ordered body centered cubic (BCC) and a disordered BCC phases, and typical dendritic structures including dendritic (DR),...
