MAGNESIUM ALLOY PLATE AND METHOD FOR PRODUCTION THEREOF

摘要

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 DEG 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 DEG C to 300 DEG 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. <IMAGE>
