Mechanical alloying (MA) of Al60Ti40 (wt%) has been successfully done by using a planetary ball mill having mixed balls of 5 mm and 15 mm diameter to refine the crystallite size of the elemental powder and to get the new MAed phase of AlTi. The microstructural and morphological analysis of elemental as well as the processed powder was done with help of Scanning Electron Microscope and X-Ray diffraction technique. Mechanical alloying of elemental Al and Ti resulted in the formation of AlTi phases with the reflection of α-Ti₃Al and TiAl₃. The average particle size was reduced around 7 times after 60 h of milling. The mean crystallite size of MAed powder was also reduced up to 85 nm after 60 h of mechanical alloying under controlled conditions.

机械合金化合成Ti-Al金属间化合物的表征

通过使用直径为5 mm和15 mm的混合球的行星式球磨机成功地完成了Al60Ti40（wt％）的机械合金化（MA），以细化元素粉末的微晶尺寸并获得AlTi的新MAed相。借助扫描电子显微镜和X射线衍射技术对元素粉末和加工粉末进行了微观结构和形态分析。元素Al和Ti的机械合金化导致形成的AlTi相的用α-Ti组成的反射₃ Al和TiAl金属₃。研磨60小时后，平均粒径降低了约7倍。在受控条件下机械合金化60小时后，MAed粉末的平均微晶尺寸也减小到85 nm。
