| 摘 要： | 通过光学显微观察、扫描电镜等实验手段对AZ91D镁合金在时效处理过程中组织和性能的变化规律进行了研究,结果表明:时效析出相可大大增加合金的硬度值,但当析出达到一定程度后,合金硬度稳定在较高的水平上;时效可使沉淀相大量析出,强化效果明显,可显著提高材料的性能.

| Abstract: | The variable rules of contexture and performance of AZ91D magnesium alloy in the course of aging treatment have been investigated with the aids of OM and SEM.It has been concluded that the aging precipitated phase can greatly increase the hardness value of the alloy,but the degree of hardness of the alloy keeps at the higher level when the number of precipitated phase reaches a given degree;and the aging can make precipitated phase separate out considerably with noticeable strengthening effect,which greatly increases the material performance. |
