Effects of Sintering Process on Microstructure and Properties of Coarse Grained Cemented Carbide AITranslate
Abstract AITranslate
WC-12%Co coarse grained cemented carbides were prepared by vacuum sintering and low pressure sintering with coarse grained WC as the raw material.The microstructure and properties of the coarse grained cemented carbides prepared by different processes were investigated by using scanning electron microscopy,optical metallographic microscopy,and microhardness,coercive force and bending strength tests.The results show that compared with vacuum sintering,low pressure sintering can improve the comprehensive performance of the coarse grained cemented carbide.As the inert gas pressure in the furnace increases from 2 MPa to 5 MPa,all the density,coercive force,hardness,flexural strength and impact toughness of the coarse grained cemented carbide have no obvious change.
