Preparation of WC cemented carbide without metallic binder toughened by MgO-B2O3 via spark plasma sintering at 1400℃

In order to reduce the sintering temperature and obtain higher fracture toughness of WC cemented carbides without metallic binder, WC cemented carbide was toughened by MgO and B2O3. Dense WC-MgO-B2O3 bulk materials were prepared at the relative low temperature of 1400℃ via spark plasma sintering(SPS...
