alpha+beta and beta-Ti matrix composites reinforced with TiC particles were synthesized by reactive arc-melting method from Ti-Fe-C-N and Ti-Cr-C-N system. It is found that plate-like alpha-Ti precipitates in the TiC particles when nitrogen is more than 3% and Fe is less than 8% in Ti-Fe-C-N system, and N is more than 2% and Cr is less than 11% in Ti-Cr-C-N system, respectively. It is seemed that Ti2C affects alpha-Ti precipitation in both systems. alpha-Ti precipitates more with increasing nitrogen contents. Accordingly, hardness of TiC decreases. However, that of Ti matrix increases with increasing nitrogen content due to solid solution hardening. Based on TEM observation, crystallographic relationship with TiC particles and precipitated alpha-Ti is described as [011] TiC//[1120] Ti, (111)TiC//(0001)Ti.

以Ti-Fe-C-N和Ti-Cr-C-N体系为原料，采用反应弧熔炼法制备了TiC颗粒增强的α+β和β-TiC基复合材料。结果表明，在Ti-Fe-C-N体系中，当N含量大于3%、Fe含量小于8%时，TiC颗粒中有片状α-Ti析出；在Ti-Cr-C-N体系中，当N含量大于2%、Cr含量小于11%时，TiC颗粒中有片状α-Ti析出。在这两个系统中，Ti2C似乎都会影响α-Ti的析出。随着氮含量的增加，α-钛的析出量增加。相应地，TiC的硬度降低。然而，由于固溶硬化，随着氮含量的增加，钛基合金的强度也随之增加。根据电子显微镜观察，TiC颗粒与析出的α-Ti的结晶学关系为[011]TiC//[1120]Ti，(111)TiC//(0001)Ti。
