| 摘 要： | 以Ｔｉ，Ａｌ，Ｃ粉末为原料，用热爆反应法制备了原位ＴｉＣ颗粒增强的ＴｉＣ／Ａｌ的Ａｌ基复合材料。研究了Ｔｉ－Ａｌ－Ｃ系热爆合成过程，探讨了热爆合成ＴｉＣ粒子的形成机制。研究表明：生成的ＴｉＣ粒子呈球形，尺寸均匀，且随体系中含Ａｌ量的增加，热爆反应合成ＴｉＣ的温度降低，ＴｉＣ颗粒尺寸减小。

| Abstract: | An aluminum matrix composite reinforced with TiC particles in-situ prepared by combustion synthesis of Ti-Al-C system was obtained. Possible reactions in Ti-Al-C system and the formation mechanism of TiC particles have been studied. TiC particles obtained in this work have a spherical shape and narrow size distribution. The synthesis temperature and the particle size of TiC decresae with an increase of aluminum content. |
