Abstract (en)
[origin: EP0540054A1] An alloy having a composition represented by the general formula, AlaNibXcMd, wherein X is at least one element selected from the group consisting of La, Ce, Mm, Ti and Zr; M is at least one element selected from the group consisting of Fe, Co, Y, Nb, Hf, Ta and W; and a, b, c and d are, in atomic percentages, 85 & a & 94.4, 5 & b & 10, 0.5 & c & 3 and 0.1 & d & 2. The aluminum-based alloy has a high strength and a high toughness and can maintain the excellent characteristics provided by quench solidification even when subjected to thermal influence at the time of working. In addition, the alloy material has a high specific strength due to minimized addition of elements having a high specific gravity.
