Abstract (en)

[origin: WO8908154A1] Magnesium alloys having a breaking load of at least 290 MPa, in particular at least 330 MPa, having the following composition: Al 2-11 %, Zn 0-12 %, Mn 0-0,6 %, Ca 0-7 %, but with at least the presence of Zn and/or Ca, having an average particle size less than 3 mum, a homogeneous matrix reinforced by intermetallic compounds smaller than 1 mum precipitated at the grain boundaries, this structure remaining unchanged after being maintained for 24h at 200 DEG C; process for producing them by rapid solidification and consolidation by extrusion at a temperature between 200 and 350 DEG C.
