Effects of HfC Particles on Crack Initiation and Propagation Behavior of WC/Co Composites
Tungsten carbide composites were prepared by cold-pressing and hot-pressing sintering; fracture toughness and bending strength of the specimens were tested. The microstructures of HfC/WC/Co composites were observed with the SEM. The mathematical models were established to investigate the relationshi...
