WC-Co cemented carbides were consolidated using spark plasma sintering in the temperature 1400°C with transition metal carbides addition. The densification depended on exponentially as a function of sintering exponent. Moreover, the secondary (M, W)C_x phases were formed at the grain boundaries of WC basal facet. Corresponded, to increase the basal facets lead to the plastic deformation and oriented grain growth. A higher hardness was correlated with their grain size and lattice strain. We suggest that this is due to the formation energy of (M, W)C_x attributed to inhibit the grain growth and separates the WC/Co interface.
