The advantage of this process is that it allows very quick densification to near theoretical density and prohibition of grain growth in nanomaterials. The addition of Al2O3 to WC can facilitate consolidation and improve mechanical properties. The hardness and fracture toughness of WC-Al2O3 composites outperform those of monolithic Al2O3.
