Compacted and consolidated material of aluminum-based alloy and process for producing the same.

摘要

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: AlaNibXcMd, AlaNibXcQe or Ala'NibX cMdQe, 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 & a & 94.4, 83 & a' & 94.3, 5 & b & 10, 0.5 & c & 3, 0.1 & d & 2 and 0.1 & e & 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.
