Abstract
The in-situ SiC particulate (5 vol% and 10 vol%) reinforced Fe2.5CoNiCu high entropy alloy (HEA) matrix composites were fabricated via vacuum inductive melting. The matrix of the HEA composites consists of single FCC phase. Both the ultimate tensile strength (UTS) and ductility of the SiC/Fe2.5CoNiCu composites were significantly improved with the increase of SiC volume fraction. The solid-solution strengthening and dispersion strengthening are the governing mechanisms responsible for the strength enhancement.
