| Abstract |
A study was carried out on the dependence of mechanical alloying on the process variables for the Al-Ti alloy in order to determine the optimal MA process condition. The homogeneity of composite particles was able to be obtained by the following condition; addition of 1.5wt.% stearic acid as PCA, the attrition velocity of 400rpm and MA milling time more than 10hrs. The MA powder prepared by the above condition reveals the achievement of a steady state processing, i. e., equiaxed powder particles, constant powder size distribution and a saturated hardness. Also, the intermetallic compound phase of Al₃Ti in the matrix was identified by X-ray diffraction analysis |
