Abstract

The phase structure and fine-microstructure of in-situ vanadium carbide formed during solidification in cast high-speed steel were studied and observed through high resolution electron microscope (HREM). In addition, the different micro-area compositions in vanadium carbide were analyzed via energy-dispersive spectroscopy (EDS). The results show that vanadium carbides are characterized by large amounts of MC-type nano-particles carbides, an enriched Mo element, distributed in a matrix composed of VC (FCC lattice) and V6C5 (HCP lattice). MC-type nano-particles are coherent or partially coherent with a matrix of vanadium carbide.
