| Abstract: | In this paper,the green compacts which use nano-WC-8Co powder and grain growth inhibitors VC,Cr3C2,TaC as raw material formed by metal die and cold isostatic pressing(CIP),then nano-sized WC-8Co cemented carbide was obtained after vacuum-sintering.The effect of cold isostatic pressing on the shrinkage,relative density,hardness of the nano-sized WC-8Co cemented carbide were studied,results indicate that the cemented carbides has the lower shrinkage,higher relative density and hardness after cold isostatic pr... |
