Abstract An innovative way to synthesize tungsten carbide-vanadium carbide core-shell structure powders, which are predicted to act as inhibitors for cemented carbides, has been explored. The core-shell structures were synthesized by chemically induced precipitation and carbonization reactions. The cemented carbides with a homogeneous microstructure were prepared at 1400 °C. The existence of tungsten carbide-vanadium carbide core-shell structure can significantly refine tungsten carbide grains, inhibit the abnormal growth of finer grains in the liquid sintering and improve the mechanical properties of the hard metals.
