Effect of carbon addition on self-propagating magnesium reduction synthesis of TiCN powder

In the process of self-propagating magnesium reduction synthesis of Ti(C, N) powder, the effects of carbon addition on phase composition, chemical composition, microstructure of TiC_1-xN_x powder were investigated. Experimental results demonstrate that carbon content of product increases and N content of product reduces with increasing of carbon addition, but high carbon addition leads to free carbon, and low carbon addition leads to high O content. When carbon addition is between 0.3mol and 0.7mol, the performance of TiC_1-xN_x powder is the best. The grain size of product reduces gradually with increasing of carbon addition.
