Method for manufacturing high-strength wrought magnesium alloy by conducting aging treatment prior to plastic working and high-strength wrought magnesium alloy manufactured thereby

摘要

(A) preparing a magnesium alloy billet; (B) homogenizing heat treatment of the magnesium alloy billet; (C) aging the homogenized heat-treated magnesium alloy billet; And (d) subjecting the aged magnesium alloy billet to hot or warm working. According to the present invention, there is provided a method for producing a magnesium alloy material, comprising the steps of: pre-aging (before homogenization heat treatment, The precipitation hardening can be prevented by forming a large amount of fine secondary phase precipitates in the magnesium alloy grain boundaries and matrix and inhibiting the crystal growth of the dynamic recrystallized grains formed during the calcining process, Magnesium alloy processing material of high strength can be manufactured through the improvement of the strength due to grain refinement as well as the effect.;
