系统探究了稀土元素Gd(0~0.8%,质量分数,下同)对ZM21(Mg-2Zn-1Mn)镁合金显微组织与力学性能的影响。结果表明,Gd添加显著细化铸态枝晶组织,促进Mg-Zn-Gd三元相(

相)析出;挤压态合金晶粒尺寸随Gd含量增加持续减小(ZM21-0.8Gd平均晶粒尺寸为3.78 μm),并弱化基面织构强度。另外,ZM21-0.8Gd合金在挤压方向(ED)的屈服强度(204 MPa)、抗拉强度(339.6 MPa)及45°方向的伸长率(35.9%)均达最优,杯突值(

The effects of rare earth Gd (0~0.8%) on microstructure and mechanical properties of ZM21 (Mg-2Zn-1Mn) alloy were systematically investigated. The results indicate that as-cast dendritic
structure is significantly refined after Gd addition, and the precipitation of Mg-Zn-Gd

-phase is promoted. The grain size of as-extruded alloys is continuously decreased with increasing Gd content (average grain size of ZM21-0.8Gd is 3.78 μm), accompanied by a weakening of basal texture intensity. Meanwhile, ZM21-0.8Gd alloy exhibits desirable performance with yield strength of 204 MPa, tensile strength of 339.6 MPa along extrusion direction (ED), and elongation of 35.9% at 45° direction, and Erichsen value (
