Titanium and boron powders were mixed with various contents of molar ratio Ti/B=1/2 to aluminum powder and then the mixture was mechanically alloyed for various milling times. Aluminum phase super-saturated with titanium and boron is formed by the mechanical alloying for belonged milling time and the crystalline size of α-Al phase in the powder particle with high Ti/B content becomes to nanometer order. Vickers hardness of the mechanically alloyed powder particles increases with milling time and of Ti/B contents. Al-5mass%Ti and Al-20mass% (Ti/B) powders mechanically alloyed for 108ks were heat-treated for various times at 723-873K in argon atmosphere. When the Al-20mass%(Ti/B) powder was heat-treated at temperature range of 723-823K, the age-hardening phenomenon occurs and Vickers hardness of the particles becomes to higher.
