Mg-3Al-1 Zn-0.2Mn（重量%）合金的晶粒细化合金进行了严格的塑性加工与口径轧制。合金的屈服强度提高到400 MPa以上，这是初始挤压合金的两倍，并且其在压缩对拉伸中的屈服不对称性通过由剪切变形引起的弱化的基面织构而减小。
Grain refinement of an Mg–3Al–1Zn–0.2Mn (wt.%) alloy was conducted by severe plastic working with caliber rolling. The alloy’s yield strength was increased to more than 400MPa, which is twice that of an initially extruded alloy, and its yield asymmetry in compression against tension was reduced by the weakened basal texture caused by the shear deformation.
