Ductility enhancement through texture control and strength restoration through subsequent age-hardening in Mg-Zn-Zr alloys

Abstract

Hot plus warm rolling combined with an aging treatment was applied to Mg-Zn-Zr magnesium alloys for exploring the possibility of producing magnesium alloys capable of exhibiting good sheet formability at room temperature through texture control while becoming greatly strengthened after the sheet forming process using an aging treatment. Uniform ductility was significantly improved due to basal texture weakening. A considerable amount of strength loss due to the texture weakening could be restored by the subsequent aging treatment.
