Abstract (en)
[origin: EP0643145A1] High strength magnesium-based alloy materials having a microcrystalline composite structure, the alloy materials consisting of a composition represented by the general formula (I): MgaNdbZnc, wherein a, b and c are, in atomic %, 80 </= a </= 99, 1 </= b </= 12 and 0 </= c </= 12; or the general formula (II): Mga'Ndb'Znc', wherein a', b' and c' are, in atomic %, 95 < a' </= 99, 1 </= b' </= 3 and 0 </= c' </= 3. The alloy materials have superior mechanical properties as high specific strength materials and plastic working materials and are produced by rapidly solidifying a molten alloy represented by the general formula (I) or (II) so as to form a fine-grained matrix phase; and subjecting the resultant rapidly solidified alloy to plastic working at a prescribed heating temperature for work hardening, thereby forming a microcrystalline composite structure having a dispersion of the fine intermetallic compounds in the matrix.
