A novel Al0.5V0.1FeCrMnNi0.9 high-entropy alloy was designed to achieve enhanced strength and plasticity.The as-cast Al0.5V0.1FeCrMnNi0.9 alloy shows a typical dendritic microstructure consisting of a body-centered cubic-structured matrix phase and a B2-structured nanoprecipitate phase.Nanoprecipitates are homogeneous and dispersed in the matrix.The as-cast Al0.5V0.1FeCrMnNi0.9 alloy exhibits a compressive yield strength of 1.104 GPa,a fracture strength of 2.926 GPa,and a fracture strain of 45.7％.The product of strength and plasticity of this alloy is 133.72 GPa％,which is superior to that of most of the reported high-entropy alloys.The strengthening mechanisms were evaluated in detail,which indicates that the coherent pre-cipitation enhancement contributes to the unusually high strength and plasticity.
