ABSTRACT:
A high strength, heat resistant aluminum-based alloy having a composition represented by the general formula Al.sub.bal Ti.sub.a Fe.sub.b or the general formula Al.sub.bal Ti.sub.a Fe.sub.b M.sub.c, wherein M represents at least one element selected from among V, Cr, Mn, Co, Y, Zr, Nb, Mo, Ce, La, Mm (misch metal), Hf, Ta and W; and a, b and c are, in weight percentage, 7.ltoreq.a.ltoreq.20, 0.2.ltoreq.b.ltoreq.6 and 0<c.ltoreq.6. A compacted and consolidated aluminum-based alloy having high strength and heat resistance is produced by melting a material having the above-specified composition, rapidly solidifying the melt into powder or flakes, compacting the resulting powder or flakes, and compressing, forming and consolidating the compacted powder or flakes by conventional plastic working.
