| 摘 要： | 为了开发低成本、高强度、耐高温的新型镁合金,研究了微量Y、Ce对AZ91D镁合金显微组织和力学性能的影响。研究结果表明:Y和Ce复合加入AZ91D镁合金,能明显细化组织晶粒,从而改善合金在室温和高温下的力学性能。当加入0.6%Ce-0.3%Y(质量分数)时,合金晶粒细化效果较好,其室温和高温力学性能比较理想。

| Abstract: | To develop magnesium alloy with low cost,high strength and excellent elevated temperature properties, effect of Y and Ce addition on microstructure and mechanical properties of AZ91D magnesium alloy were studied. Result shows that addition of a small amount of Y and Ce to AZ91D alloys results in refinement of microstructure. Owing to the improvement of microstructure, the mechanical properties of alloys at both ambient and elevated temperatures are increased. 0.6% Ce- 0.3%Y addition to AZ91D has good refinement effect and brings about relatively ideal mechanical properties. |
