| 摘 要： | 采用金相显微镜、电子探针、扫描电镜、X-射线衍射仪及电子万能拉伸试验机等设备分析研究了Nd对Mg-Zn-Y合金的显微组织和力学性能的影响。显微组织观察表明:稀土Nd能够明显起到晶粒细化的作用,改善了实验合金的显微组织。力学性能测试表明:由于稀土Nd的添加提高了合金的力学性能,并且当Nd添加量为0.5%时,合金的综合力学性能最佳,抗拉强度达到207MPa,伸长率达到16.9%,硬度达到52.8HV。

| Abstract: | The effects of Nd on microstructure and mechanics properties of Mg-Zn-Y alloys have been analyzed by using metallographic microscope,electron probe micro-analyzer (EPMA),scanning electron microscopy(SEM),X-ray diffraction(XRD)and electronic universal materials testing machine, resulting in that the grain of alloy was obviously refined and microstructure of alloy improved with Nd addition. The mechanics properties experiments indicated that the mechanics properties of experimental alloys were improved with N... |
