研究了Ａｌ含量和Ｃ／Ｔｉ对Ａｌ＋Ｔｉ＋Ｃ复合系热爆反应合成Ａｌ／ＴｉＣ的反应过程及生成相组成的影响。实验结果表明：随着Ａｌ含量的增加，反应温度降低，反应时间延长，但反应起始温度几乎没有变化；Ｃ／Ｔｉ对反应温度和反应时间有很大的影响，但对反应起始温度影响很小。在对生成相组成的研究中发现：当Ｃ／Ｔｉ＝１．２５、Ａｌ含量不大于６０ａｔ％和Ｃ／Ｔｉ＝１、Ａｌ含量不大于５０ａｔ％时，生成物只有ＴｉＣ；随着Ａｌ含量的增加，生成Ａｌ＿３Ｔｉ的量增加，并通过热力学理论对反应合成自由能进行了计算，计算结果与试验结果相吻合。另外，通过扫描电子显微镜（ＳＥＭ）对生成的ＴｉＣ的组织形貌进行了观察。结果表明：生成的ＴｉＣ尺寸均匀，约为０．３～０．８μｍ，大多数呈球状，部分为块状。
The effects of Al content and C / Ti on the reaction process and phase composition of Al / TiC synthesized by thermal explosion reaction of Al + Ti + C composite system were studied. The experimental results show that the reaction temperature decreases and the reaction time prolongs with the increase of Al content, but the reaction start temperature has almost no change; C / Ti has a great influence on the reaction temperature and reaction time, but the influence on the reaction initiation temperature Very small. In the study on the phase composition, it was found that the product had only TiC when C / Ti = 1.25, Al content was not more than 60at% and C / Ti = 1, Al content was not more than 50at% The amount of Al_3Ti generated increases, and the free energy of reaction is calculated by the thermodynamic theory. The calculation results are consistent with the experimental results. In addition, the morphology of the resulting TiC was observed by a scanning electron microscope (SEM). The results show that the size of TiC is about 0.3 ~ 0.8μm, most of which are spherical and partly massive.
