PURPOSE:To provide an aluminum base alloy compacted material high in strength and having elongation enough to withstand practical working. CONSTITUTION:This cover is a one obtd. by accumulating and compacting a rapidly solidified material having a compsn. of a general formula: AlaNrbXcMd or Ala' NibXcMdQe (where X denotes La, Ce and Mm, M denotes Zr and Ti, Q denotes Mg, Si, Cu and Zn as well as, by at%, 84<=a<=94.8, 82<=a'<=94.6, 5<=b<=10, 0.1<=c<=3, 0.1<=d<=3.0 and 0.2<=2<=2 are satisfied) and a method in which the powder or thin piece obtd. by executing rapid solidification is accumulated and is compacted by usual plastic working means. At the time of executing secondary working, this material has elongation enougt to withstand the above working, and furthermore, the excellent characteristics of the raw material can be maintained as they are. Moreover, the solidified material having the above effects can be provided by a simple method. |
