Advanced Engineering Materials, EarlyView.AlCrFeCoNi high entropy alloy coating is applied on steel using electrospark deposition. The microstructure evolution and phase transformation of the as‐deposited and heat‐treated coatings is characterized and discussed. Reduced microhardness and yield strength are measured after heat treatment.
