Abstract
Process for economically obtaining a magnesium alloy having improved mechanical characteristics and in particular a breaking strength of at least 290 MPa and an elongation at break of at least 5%, by spraying and deposition in solid form to provide an ingot with the following weight composition: Al 2-9%; Zn 0-4%; Mn 0-1%; Ca 0.5-5%; RE 0-4% (rare earths); and, with the main impurities, the remainder being magnesium. The ingot undergoes a consolidation treatment by thermal deformation at between 200.degree. and 250.degree. C. The alloys obtained by the process are constituted by a homogeneous magnesium matrix with the grain size between 3 and 25 .mu.m and particles of intermetallic compounds.
