摘要
介绍了几种常用镁合金,并说明了稀土元素加入到这些镁合金中,对其组织和性能的影响。讨论了Ce、Y、Nd、Sc等主要稀土元素在镁合金中细化晶粒、提高镁合金力学性能的机理。对稀土镁合金的应用和发展进行了评价和展望。
This paper introduces some common widely used mag- nesium alloys and the effects of the main rare earth elements on microstrueture and properties of magnesium alloys after mixed them together.The mechanism of grain refinement and mechani- cal properties in magnesium alloys by Ce,Y,Nd,and Sc are dis- cussed.The application and development for rare earth-magnesi- um alloys development and application prospects for are ana- lyzed.
