| 摘 要： | 利用光学显微镜、电子扫描、X射线衍射分析方法研究Gd对AZ81镁合金显微组织的影响.结果表明,合金的显微组织主要由α-Mg基体、β-Mg_(17)Al_(12)相、Al_2Gd相组成.Gd的加入使β-Mg_(17)Al_(12)相显著减少,Gd含量较低时AZ81镁合金的晶粒得到细化、组织较为均匀.随Gd的增加,β-Mg_(17)Al_(12)相有粗化、偏聚的趋势.

| Abstract: | The effects of gadolinium on the microstructure of AZ81 magnesium alloy are investigated by optical microscope, SEM and X-ray diffraction analyzer. The results show that magnesium alloys with Gd mainly consist of α-ME matrix, β-Mg_(17)Al_(12) phase and Al_2Gd phase. The microstructure of AZ81 alloy with addition of gadolinium is refined and homogeneously, the volume fraction of β-Mg_(17)Al_(12) phase is decreased. The β-phase are congregated and coarsened with the excessive Gd addition. |
