摘要
A method of manufacturing a cold-rolled magnesium alloy sheet for improving formability, including, (a) preparing a composite sheet which is composed of a main sheet made of magnesium alloy and a restrainer made of steel and functioning to suppress transverse plastic deformation (plastic deformation in a transverse direction) of the main sheet during a rolling process, (b) performing a cold-rolling of the composite sheet, and (c) separating the cold-rolled magnesium alloy sheet from the cold-rolled composite sheet obtained from (b). The magnesium alloy sheets manufactured by the invention has improved formability at an ambient temperature, and thus can be usefully applied to extensive industrial fields such as automobiles and aircrafts.
