ABSTRACT:
An Al-based alloy represented by the general formula Al.sub.bal Ti.sub.a M.sub.b and Al.sub.bal Ti.sub.a M.sub.b Q.sub.c wherein M represents at least one element selected from among V, Cr, Mn, Co, Cu, Y, Zr, Nb, Mo, Hf, Ta and W; Q represents at least one element selected from Mg and Si; and a, b and c are, in percentages by weight, 7.ltoreq.a.ltoreq.20, 0.2.ltoreq.b.ltoreq.20 and 0.1.ltoreq.c.ltoreq.5. A compacted and consolidated material are produced by melting a material having the above alloy composition, rapidly solidifying the melt into powder or flakes; compacting the resultant powder or flakes; and subjecting the compacted powder or flakes to press forming and consolidating by a conventional plastic working. The aluminum-based alloy and the compacted and consolidated material thereof have a high strength and a good ductility and an excellent strength at high temperature.
