- 摘要:
- 追求更高强度的材料一直是结构材料研究人员的目标,尤其是轻质结构材料-镁合金,被誉为“21世纪最轻的结构合金”。低密度、高性能镁合金在各种技术应用中非常具有吸引力,特别是在镁合金中加入主要合金化元素后,其强度、塑性得到了极大提升,从而促进了不同合金体系的镁合金发展。本研究综述了铸造镁合金和变形镁合金的研究和发展现状。重点从合金体系、合金组成、制备工艺和力学性能等方面进行综述,旨在对未来设计强度更高、综合性能优异的镁合金提供参考。
The pursuit of higher-strength materials has always been the goal pursued by researchers in structural materials,
especially magnesium (Mg) alloys, which are lightweight structural materials known as “ the lightest structural alloy of the
21st century ” . Low-density, high-performance Mg alloys have become very attractive in various technical applications,
especially with the addition of major alloying elements in Mg alloys, which greatly enhance their strength and plasticity and
further promote the development of Mg alloys with different alloying systems. From this aspect, this review summarizes the
research and development status of cast Mg alloys and wrought Mg alloys. Highlights are reviewed from the perspectives of
alloying systems, alloy composition, preparation processes, and mechanical properties, aiming to provide a reference for the
future design of higher-strength Mg alloys with excellent overall properties.
