Synthesis of Nanocrystalline TiC_1-xN_x by High Energy Milling

Abstract:

The nanocrystalline TiC_1-xN_x powders were synthesized by high energy milling from the mixture of Ti and carbon black in nitrogen milling atmosphere. The phase transformation and powder morphology characteristics were studied by using XRD and SEM. The results show that nanocrystalline TiC_1-xN_x powders were fabricated successfully by milling for 24 h at a rotational speed of 450 rpm in planetary ball-mill. The formation mechanism was mechanically induced self-propagating reactive synthesis (MSR). According to changing the mole ratio of C to Ti, serial TiC_1-xN_x powders can be produced, including TiC₇N₃, TiC₅N₅, and TiC₃N₇.
