将纯Ｔｉ粉石墨粉按原子比１：１的比例混合配成Ｔｉ＿（５０）Ｃ＿（５０）混合粉，球料重量比为１０：１，用高能球磨的方法在行星球磨机上进行机械合金化实验。对球磨不同时间（０，５，４０，６０，８０ｈ）的粉末样品用ＸＲＤ、ＴＥＭ、ＳＥＭ进行了结构和形貌分析，结果表明，球磨初期，Ｃ原子向Ｔｉ晶格及晶界扩散，形成Ｔｉ的过饱和固溶体，致使衍射谱上石墨衍射峰消失；进一步球磨，此过饱和固溶体可以形成纳米晶结构，其晶粒尺寸大小约为２０～５０ｎｍ，球磨４０ｈ后混合粉中有ＴｉＣ生成，但单纯通过机械合金化法不能使Ｔｉ＿（５０）Ｃ＿（５０）混合粉末完全转变为ＴｉＣ。
The pure Ti powder was mixed at Ti: (50) C 50 by the atomic ratio of 1: 1, the weight ratio of the ball material was 10: 1, mechanical alloying was performed on a planetary ball mill by high energy ball milling experiment. The results of XRD, TEM and SEM showed that the C atoms diffused into the Ti crystal lattice and the grain boundary during the initial ball milling. Ti supersaturated solid solution, resulting in the disappearance of graphite diffraction peaks on the diffraction spectrum; further milling, the supersaturated solid solution can form a nanocrystalline structure, the grain size of about 20 ~ 50nm, after milling 40h TiC mixed powder, Pure Ti_ (50) C_ (50) mixed powders can not be completely transformed into TiC by simple mechanical alloying.
