摘要：
A new approach to produce nanophase WC/Co/VC/TaC powder was developed by thermochemical processing method for improving the mechanical properties. To overcome coarsening and abnormal grain growth of the WC particles for nanophase WC/Co during the sintering, VC/TaC, VC, and TaC are used as the grain growth inhibitors by mechanical and chemical process. Nanophase WC/Co eloped VC and VC/TaC by mechanical mixing was shown nanoscale microstructure, but exaggerated local grain growth was observed due to non-uniform distribution of grain growth inhibitors Nanophase WC/Co/VC/TaC synthesized by chemical process was shown ultrafine microstructure without local grain growth microstructure and mechanical properties of nanophase WC/Co/VC/TaC are compared with those of commercial submicron WC/Co/VC/TaC.
