Three mixtures of elemental powders of Al-25at.%Ti, 48at.%Ti and 70at.%Ti were offered to ball milling process for the formation of intermetallic compounds of , AlTi and . Ballmilling or attrition process were carried out at the condition of rotaing speed of 110 or 350 rpm at torr vacuum or argon atmospheres. phases were fully obtained by heat treatment for 1 hors at with Al-25at.%Ti composition mixtures milled by 100 hours. The amorphous phase was completely formed at the composition of Al-48at.%Ti mixed powders by milling 100hours at the 50 to 1 weight ratio of ball to powder, and AlTi compounds were obtained by heat treament. In the case of Al-70at%Ti mixed powders milled for 100 hours, and intermetallic compounds were formed by heat treatment for 1 hour at . By attrition milling of 350rpm for 10 hours, phase was formed completley after heat treatment for 1 hour at .
