In-situ alloying has been demonstrated to be an effective method for modifying the microstructure of additively manufactured titanium alloys. In this paper, the influence of trace TiC powder addition on the microstructure and mechanical properties of wire arc additive manufactured Ti-6Al-4V alloy was investigated. The result showed that the trace TiC powder addition reduced the size of columnar β grains and refined the α-Ti phase in the Ti-6Al-4V alloy, and the microstructure was the fine basketweave structure, and the ultimate tensile strength and elongation reached
