The mechanical alloying of intermetallic compounds has attracted much attention in recent years. The formation of NiAl with B2 structure by mechanical alloying of Ni and Al powder mixture has been found to be an explosive exothermic reaction. In this paper, Ti and Fe elements were substituted for Al
The mechanical alloying process of A1-25at.%Ti mixed powders has been investigated in Ar gas and in air using an attritor type of ball mill. Refinement of mechanically-alloyed powder particles proceeds faster in air than in Ar. However, dissolution of Ti into A1 powders proceeds more slowly in air t
