稀土镁合金的研究

INVESTIGATIONS ON THE RARE EARTH-CONTAINING MAGNESIUM ALLOYS (A REVIEW)

本文总结了稀土镁合金的研究工作。概要论述了稀土镁合金的发展进程;在稀土元素对镁合金性能影响方面,阐明了稀土元素对镁合金密度、电阻系数和导热系数、热膨胀系数、阻尼容量、晶格常数、弹性模量等物理性能以及对拉伸和蠕变等力学性能的影响。在稀土镁合金微观结构研究方面,总结了稀土相的结构,以及稀土相对合金的强化作用,并提出了我们的一些研究结果。

A review was made on the investigations of the rare earth (RE)containing magnesium alloys. The development process of RE-containing magnesium alloys was briefly summarized firstly.The effects of RE to the physical and mechanical properties of magnesium alloys were expounded. In this paper, the microstructural studies on phase structures and the strengthening effects of RE on the magnesium alloys were concerned. In addition, some of our new researching results were also presented.
