Compacted and consolidated aluminum-based alloy material and production process thereof

摘要

A compacted and consolidated aluminum-based alloy material is obtained by compacting and consolidating a rapidly-solidified material having a composition represented by the general formula: AlaNibXcMd or Ala'NibXcMdQe, wherein X is one or two elements selected from La and Ce or an Mm; M is Zr or Ti; Q is one or more elements selected from Mg, Si, Cu and Zn, and a, a', b, c, d and e are, in atomic percentages, 84 & a & 94.8, 82 & a' & 94.6, 5 & b & 10, 0.1 & c & 3, 0.1 & d & 3, and 0.2 & e & 2. According to the production process of the invention, powder or flakes obtained by rapidly solidifying are compacted, followed by compressing, forming and consolidating by conventional plastic working operations. The consolidated material has elongation sufficient to withstand secondary working operations. Moreover, the material can retain excellent properties of its raw material as they are.
