Abstract

It remains a challenge to enhance strength without sacrificing ductility for high entropy alloys. Here, we prepared in-situ TiC/FeCrNiCuV0.1 high entropy alloy matrix composites using vacuum induction smelting. The new composites exhibit an excellent combination of high tensile strength (1006.5 MPa) and good ductility (15.6%). The improved mechanical properties, as compared to the V-free composites, are attributed to a synergy of solid solution strengthening and grain size refinement.
