ABSTRACT:
A compacted and consolidated material of an aluminum-based alloy obtained by compacting and consolidating a rapidly solidified material having a composition represented by the general formula: Al.sub.a Ni.sub.b X.sub.c M.sub.d, Al.sub.a Ni.sub.b X.sub.c Q.sub.e or Al.sub.a 'Ni.sub.b X.sub.c M.sub.d Q.sub.e, wherein X represents at least one element selected from the group consisting of La, Ce, Mm (misch metal), Ti and Zr; M represents at least one element selected from the group consisting of V, Cr, Mn, Fe, Co, Y, Nb, Mo, Hf, Ta and W; Q represents at least one element selected from the group consisting of Mg, Si, Cu and Zn; and a, a', b, c, d and e are, in atomic percentages, 85.ltoreq.a.ltoreq.94.4, 83.ltoreq.a.ltoreq.94.3, 5.ltoreq.b.ltoreq.10, 0.5.ltoreq.c.ltoreq.3, 0.1.ltoreq.d.ltoreq.2 and 0.1.ltoreq.e.ltoreq.2. The material is produced by melting a material having the above specified composition, quench-solidifying the melt, compacting the resultant powder or flakes, and subjecting the thus-compacted material to press forming and consolidating by a conventional plastic working technique.
