摘　　要：探索了结合复压复烧和瞬间液相烧结工艺（ＩＳＭ）制备机械合金化Ａｌ－Ｔｉ合金的方法，获得了在Ａｌ基体上弥散分布直径为（０．２～０．５）μｍ的Ａｌ３Ｔｉ颗粒，接近于理论密度的Ａｌ－Ｔｉ合金。并分析了各阶段工艺参数对压坯致密化的影响。A new processing route of synthesizing mechanically alloyed Al 8Ti powder has been investigated.The transient liquid sintering process has been combined with a double cycle of cold pressing and vacuum sintering.The near full density compacts with Al 3Ti Particles of (0 2～0 5)μm dispersed in the Al matrix have been obtained The effects of processing parameters on the densification of the compacts are also investigated
