摘　　要：采用钢球为研磨介质,以单质Al,Ti和Si为原料,对Ti30Al60-Si10,Ti50-Al40-Si10,Ti60-Al20-Si20,Ti70-Al30-Si10等在无保护气氛和非真空卒条件下进行球磨,获得了非晶态金属间化合物。XRD分析表明,在球磨约30 h就形成了Al3Ti,AlTi3, AlTi2等金属间化合物;球磨至78 h时,得到了无单质存在的Ti-Al基或Ti-Si基金属间化合物的非晶体。Amorphous intermetallic compounds of Ti-Al-Si were prepared by mechanical alloying method in air condition using Al, Ti and Si as source materials and stainless steel ball as grind medium. XRD analyses showed that intermetallic compounds, Al3Ti AlTi3.AlTi2, etc., were prepared after 30 h grinding; and Ti-Al system and Ti-Si system intermetallic compounds were achieved after 78 h grinding.
