Low-temperature mechanicothermal treatment of Al−Mg−Si alloys

1. Considerable strengthening of weakly precipitation-hardening alloys of the Al−Mg−Si system can be obtained by LTMTT (e=95%), leading to the development of texture and intensive zone decomposition of the solid solution during subsequent aging at 140°. 2. The increase in strength due to LTMTT can be increased by deformation in two stages with approximately equal deformation in each stage and totalling 95%, alternating with aging at 140°.
