| 中文摘要: |
| Mg-Al合金因其密度低、比强度高、成本低廉，成为镁合金材料中被广泛应用的系列之一。然而，Mg-Al合金时效热处理过程中所存在的非连续析出行为恶化了其力学性能，限制了其进一步的应用。介绍了Mg-Al合金中非连续析出相的形成机制，进而从时效工艺调整和添加合金元素2个方面总结了目前改性或解决非连续析出行为的研究进展，最后对未来研究措施进行了简要展望，希望为Mg-Al合金材料的研究者提供借鉴。 |
| 英文摘要: |
| Mg-Al alloy has become one of the widely used magnesium alloys due to its low density, high specific strength and low cost. However, the discontinuous precipitation behavior during the aging heat treatment of Mg-Al alloy deteriorates its mechanical properties and limits its further application. The formation mechanism of discontinuous precipitates in Mg-Al alloy was introduced. The current research progress on modificating or solving discontinuous precipitates of Mg-Al alloy were summarized according to the two aspects of adjusting aging process and adding alloy elements. Finally, the future research is briefly prospected, hoping to provide reference for the researchers of Mg-Al alloy. |
