Powder mixtures of Al/Ni and Al/Mg-Al alloy were mechanically alloyed for various milling times. In the Al-25 and 40mol%Ni powder mechanically alloyed for over 18ks, AlNi(β') phase was formed. The crystalline size of AlNi(β') phase decreases with increase of the milling time, and it become to about 30 nm. When the Mg alloy (AZ31) powder mixture with various Al contents was mechanically alloyed, Mg_<17>Al_<12> phase forms for the milling time of ks. The Al-40mass%Ni powder mechally alloyed for 180ks was hot pressed at 823K by 400〜600MPa, and the compact was compressive test under various conditions. When the compact was deformed at 973〜1123K for strain rate of 0.1〜1.0s^<-1>, enhanced ductility appears.
