摘要
论述了用扫描电镜和透射电镜研究Ｆｅ－Ｃ－Ｔｉ机械合金化粉末的制样方法，分析了该合金粉末的形态和组织结构。结果指出，合金粉末的尺寸随球磨时间增加先增大后减小，其形态由球形先变为纺锤形，后又成为球形。将最终得到的复合粉末进行真空热处理，ＴｉＣ弥散析出，而且层间界面处的ＴｉＣ尺寸较大。
The specimen preparations of mechanical alloyed Fe C Ti powders have been discussed,thier morphologies and microstructures have been studied.The results shows that the powder particle size increased at the beginning of mechanical alloying and then decreased,the powder morphology also underwent a sphere spindle sphere change.After vacuum heat treatment of the composite particles,it was clarified that TiC particles were precipitated in matrices and the size of TiC particles at interfaces was bigger than that in crystals.
