Ultrafine WC-8Co and WC-6Co cemented carbides strengthened by composite carbides were prepared by vacuum sintering and low pressure sintering,respectively.The effects of sintering method and sintering temperature on the properties and microstructure of the cemented carbides were studied.The results show that compared with vacuum sintered cemented carbide,low pressure sintered cemented carbide has fewer pores with higher density,hardness and bending strength.With the increase of low pressure sintering temperature,all the density,hardness and flexure strength of the cemented carbide increase.However,excessively high temperature during low pressure sintering could lead to abnormal growth of WC grains.
