Outline of Research of Ultra-fined Grain Al-Mg Alloys and Countermeasures for Future Study

超细晶金属材料具有高强度、超塑性等特点,具有巨大的开发与应用前景,受到世界各国的高度重视,超细晶金属材料的研究代表着目前国际材料研究的一个重要方向。Al-Mg合金由于质轻、性能好的特点,具有广阔的开发与应用潜力。对超细晶金属材料研究现状、超细晶Al-Mg合金的研究进展进行综合评述;对目前超细晶材料研究中存在的不足,以及超细晶Al-Mg合金开发与应用中存在的问题进行了分析;提出了未来的研究对策。

Due to high strength and superplasticity,etc. ultra-fined grain(UFG)metal has a great development and application potentiality and is highlighted by many countries all over the world. Ultra-fined grain metal research represents one of the most important study directions in the world at present. Because Al-Mg system alloy has a low density and good performance, it has an extensive development and application potentiality. The outline of UFG metal studies and the development status of UFG Al-Mg alloys are comprehensively summarized. In terms of the analysis of the problems and shortages of UFG Al-Mg alloy investigations, several counter-measures for future study are proposed.
