Abstract (en)
[origin: EP0524527A1] A compacted and consolidated aluminum-based alloy material is obtained by compacting and consolidating a quench-solidified material whose composition is represented by the general formula: AlaNibXc wherein X is one or more elements selected from La and Ce or an Mm (mischmetal) and a, b and c are, in atom percent, 87.5 </= a </= 92.5, 5 </= b </= 10, and 0.5 </= c </= 2.5. According to its production process, powder or flakes obtained by quench solidification are compacted, followed by compression, forming and consolidation by conventional plastic working. The consolidated material has elongation sufficient to withstand secondary working even when the secondary working is applied. Moreover, the material can retain excellent properties of its raw material as they are. The consolidated material having such advantages can be provided by the simple process. <IMAGE>
