This work presents an in-depth comparison of the microstructural origins of high strength and high wear resistance in the Al0.2Co1.5CrFeNi1.5Ti high-entropy alloy produced by powder metallurgy (PM) and casting. The PM alloy microstructure is composed almost exclusively of fine-grained FCC phase with...
