Synthesis of Nanocrystalline TiC1-xNx by High Energy Milling
The nanocrystalline TiC1-xNx 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 TiC1-xNx 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 TiC1-xNx powders can be produced, including TiC7N3, TiC5N5, and TiC3N7.
