研究了Ｔｉ_（５０）Ａｌ_（５０）混合粉末在氮气氛的机械合金化过程。球磨３０ｈ后Ｔｉ_（５０）Ａｌ_（５０）混合粉末已形成非晶合金；经适当的热处理，可原位形成纳米复合材料γ－ＴｉＡｌ＋Ｔｉ_２ＡｌＮ。
The mechanical alloying of Ti 50 Al 50 powders under nitrogen atmosphere was studied. The Ti_ (50) Al_ (50) mixed powder has been formed into amorphous alloy after ball milling for 30h. The nanocrystalline γ-TiAl + Ti_2AlN can be formed in situ by appropriate heat treatment.
