Cemented carbide powders based on WC–12Co with a grain size of 40–250nm were generated by high-energy ball milling. The powders with different extents of VC and (VC+Cr 3 C 2 ) addition were consolidated to full density by spark plasma sintering (SPS). The density, microstructure, grain size and fracture toughness K Ic of the SPS consolidated samples were measured and compared...
