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

Abstract

The present invention provides a compacted and consolidated aluminum-based alloy material which has been 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 wherein X is one or two elements selected from Zr and Ti and a, b and c are, in atomic percentages, 87.5.ltoreq.a.ltoreq.92.5, 5 .ltoreq.b.ltoreq.10, and 0.5.ltoreq.c.ltoreq.5; and a production process comprising melting a material of the above composition; quenching and solidifying the resultant molten material into powder or flakes; compacting, compressing, forming and consolidating the powder or flakes by conventional plastic working. The consolidated material of the present invention has. elongation (toughness) sufficient to withstand secondary working, even when secondary working is applied. Moreover, the material allows the secondary working to be performed easily while retaining the excellent properties of its raw material.
