Influence of different post treatments on microstructure and properties of WC-Co cemented carbides

Effects of different post treatments on microstructure and properties of WC–11 wt.% Co cemented carbides were investigated in this paper. The different post treatments that are carried out to the cemented carbides are (a) heating and quenching in oil bath, (b) controlled cryogenic treatment. Various mechanical and microstructural characterization of these alloys including density, coercive force, hardness, transverse rupture strength, phase...
