摘要：

The TiC and TiB2 powders were successfully synthesized by ball milling the Ti50C50 and Ti33B67 elemental powders, respectively. During ball milling the Ti50C50 powder, a solid solution of C in Ti, Ti(C), was first formed, followed by TiC. After milling for 80 h, the powder was composed of TiC with grain size of 6 nm and a small amount of Ti(C) which was finally completely transformed to TiC after heat treatment. During ball milling the Ti33B67 powder, a solid solution of B in Ti, Ti(B), was first formed followed by the formation of an amorphous structure which transformed into a hexagonal phase of TiB2 with grain size of about 10 nm.
