METHOD FOR MANUFACTURING OF MAGNESIUM ALLOY SHEET WITH IMPROVED FORMABILITY AND THE MAGNESIUM ALLOY SHEET THEREBY

摘要

The present invention relates to a method to manufacture a magnesium alloy sheet to improve formability and the magnesium alloy sheet manufactured by the same, and more specifically, the present invention provides the method to manufacture the magnesium alloy sheet comprising: (step 1) a step of performing compressive strain of the magnesium alloy sheet along a rolling surface direction and a direction vertical to the rolling surface direction at the same time; and (step 2) a step of annealing the magnesium alloy sheet. According to the present invention, the method to manufacture the magnesium alloy sheet has the advantage of being able to improve formability at room temperature as a crystal texture is changed to a non-basal plane; and to prevent a buckling phenomenon, and be applied in a thin sheet by performing bi-axial formation and thermal annealing.
