Abstract

The work aims to prepare in situ carbide enhanced BCC structure high-entropy alloy cladding layers, and study the effect of design content of carbide on their microstructure and mechanical properties. Therefore, in situ VC enhanced Al1.5CoCrFeNi(VC)x (x=0, 0.1, 0.2, 0.3, mole ratio) high-entropy alloy were manufactured on the Q235 steel by plasma cladding. The effect of VC design content on their phases, microstructure, and mechanical properties were analyzed.
