| 摘 要： | 研究了Al-Ti-B对AZ91D镁合金铸态显微组织和力学性能的影响，并探讨其化学成分与组织结构和力学性能之间的变化。研究结果表明：Al-Ti-B加入AZ91D镁合金，能明显细化组织晶粒，从而改善合金的室温力学性能。当加入Al-Ti-B时，合金晶粒细化效果较好，其室温力学性能和硬度比原来都有较大的提高。

| Abstract: | The effect of Al-Ti-B addition on the as-cast structure and mechanical properties of AZglD magnesium alloy were investigated. The results show that the addition of a small amount of Al-Ti-B to AZglD alloy can help refine the microstructure of the alloy and consequently improve its mechanical properties at ambient temperatures. It is also found out that the addition of Al-Ti-B can lead to good refining effect and help improve its mechanical properties. |
