| 中文摘要: |
| 泡沫镁作为一种新型功能材料，近年来逐渐受到了国内外的广泛关注，但由于镁过于活泼，易引起爆炸，难以在生产中被大量使用，故关于泡沫镁的研究较少。主要综述了泡沫镁阻尼性能、吸声性能、吸能性能、散热性能、生物医学性能和电磁屏蔽性能等几种主要的性能特点，进而综述了粉末冶金法、熔体发泡法、渗流铸造法等几种常见的泡沫镁材料制备工艺的研究进展，并结合笔者的研究理解对几种制备工艺进行了对比，分析了各种制备方法的优缺点。在此基础上对泡沫镁材料在航空航天领域上的应用进行了分析，表明了其在航空航天领域有着广阔的应用前景。 |

| As a new functional material, foam magnesium has attracted more and more attentions at home and abroad in recent years. But magnesium is too active, and it is likely to cause explosion and is difficult to be used in production. Therefore, there are few researches on foam magnesium. In this paper, the main properties of foam magnesium, such as damping capacity, sound absorption, energy absorption, heat dissipation, biomedical properties and electromagnetic shielding performance, were reviewed. The research progress of several common foam magnesium material preparation methods such as powder metallurgy method, melt foaming method and percolation casting method were reviewed. The advantages and disadvantages of various preparation methods were analyzed in combination with understanding of the authors. On this basis, the application of foam magnesium materials in aerospace field was analyzed, showing that it has broad application prospects in the aerospace field. |
