  • Publication number: 20140348696
    Abstract: A method for increasing formability of magnesium alloy sheet and the magnesium alloy sheet prepared by the same are provided, in which the method includes the following steps: forming {10-12} twins in magnesium alloy sheet (step 1); and annealing the magnesium alloy sheet of step 1 (step 2). The present invention also provides the magnesium alloy sheet containing {10-12} twins prepared by the method. Accordingly, the room temperature formability and the warm formability are increased by forming {10-12} twins through deformation on the magnesium alloy sheet and subsequently performing annealing, because it is possible to artificially form {10-12} twins without increasing dislocations in the magnesium alloy sheet and accommodate the deformation generated during the forming via annihilation of the twins.
