镁合金功能材料的研究进展

与其它结构金属材料相比镁合金具有质轻的显著优点，因此被广泛应用于交通运输和航空等领域。随着研究的深入和研究范围的扩大，镁合金更多的优点被开发利用：较高的理论能量密度，较大的阻尼容量和屏蔽效能以及良好的生物相容性，因此镁合金具有作为储氢材料、可再充电电池、阻尼材料、可生物降解的植入材料、电磁屏蔽材料、导热材料的潜力，但是每一种功能性材料都存在未解决的瓶颈问题，本文对近十年的大量的研究进行了概括，总结了镁及镁合金作为以上六种功能材料的主要研究方向及研究进展，讨论了未来主要的研究方向。

Research Progress in Magnesium Alloys as Functional Materials

Magnesium alloys have a significant advantage-low density over other structure metals currently and have been widely used in various fields such as transportation and aerospace. With the development of further research and the enlargement of research scope, more advantages have been developed: high storage capacity, high theoretical volumetric energy density, extraordinarily high damping capacity, good biocompatibility, excellent shielding efficiency as well as impressive thermal conductivity. Therefore Mg alloys have the potential to be various functional materials, such as hydrogen storage material, rechargeable electrochemical batteries, damping material, biodegradable implant material, electromagnetic shielding material, and thermal conductive material. Unfortunately, each kind of functional material has bottlenecks or troubles needing to be broken through, and a lot of researches have been carried out in recent years. This review comprehensively covers the research history, progress and the up-to-date summary of Mg and Mg alloys as functional materials. The six kinds of materials above all will be discussed respectively.
