Abstract
The invention relates to high mechanical strength magnesium alloys and to a process for producing these alloys by fast solidification and consolidation by drawing generally exceeding 400 or 500 MPa, an elongation at break of generally at least 5% and a chemical composition by weight within the following limits: ______________________________________ Aluminium 2-11% Zinc 0-12% Manganese 0-1% Calcium 0.5-7% Rare Earths 0.1-4% ______________________________________ with the main impurities and the residue being magnesium, their structure being constituted by grains with a mean size below 3 .mu.m and intermetallic compounds with a size below 2 .mu.m precipitated at the grain boundaries.
