【摘要】 镁合金是最轻的金属结构材料,而稀土的加入对改善其组织、起燃温度、耐腐蚀性、力学性能特别是高温性能具有重要作用.近几年,有关稀土镁合金国内外均做了相当多的研究,随着节能与环保要求的日益迫切,镁合金的研究与应用也越来越得到重视.本文介绍了近年来国内外稀土镁合金的研究开发状况.更多还原

【Abstract】 Magnesium alloys are the lightest metallic structure materials.When some kinds of rare earths added in,their properties had been improved,especially on the high temperature properties.In the past few years,many studies have been done on this field.Because of the requirements of protecting environment and saving energy,the research and application of magnesium alloy get more and more attention.In this paper,the development state of rare earth-magnesium has been introduced.更多还原
