ABSTRACT:
A magnesium alloy sheet having an adequate strength and an excellent bendability is provided along with a method of manufacturing such an alloy sheet. The method comprises, rolling a magnesium alloy sheet through a reduction roll, the alloy thereof containing about 0.1-10.0 mass % of Al and about 0.1-4.0 mass % of Zn, wherein the magnesium alloy sheet has a surface temperature of about 100° C. or below at the time just before it is fed in the reduction roll, and the reduction roll has a surface temperature in the range of about 100° C. to 300° C. Particularly, when executing multipass rolling, at least the last pass is accomplished in non-preheat rolling wherein the magnesium alloy sheet and the reduction roll have specified surface temperatures, respectively.
