【摘要】 镁合金作为目前实际工程应用中密度最低的金属结构材料，在轻量化需求迫切的航空航天领域具有广阔的应用前景，但“绝对强度偏低”“变形能力偏弱”和“耐蚀性能不足”三大瓶颈问题极大限制了传统镁合金在航空航天领域的应用范围。本文简要梳理镁合金在航空航天领域的应用现状，详细介绍高强韧、高耐蚀镁合金目前的研究进展，并对未来航空航天领域用高性能镁合金的研发趋势进行展望。更多还原

【Abstract】 Magnesium alloys, currently recognized as the lightest structural metallic material in practical engineering applications, have broad prospects for application in the aerospace field, where lightweight demands are increasing.However, the three major bottleneck issues, “relatively low absolute strength”, “weak deformation capacity”, and “insufficient corrosion resistance”, greatly limit the application scope of traditional magnesium alloys. Based on a review of the latest application status of magnesium alloys in the aerospace field, this paper has elaborated on the research progress of high-strength, tough, and corrosion-resistant magnesium alloys and prospected the development trends of high-performance magnesium alloys in future aerospace applications.更多还原
