合金元素对镁合金性能影响

镁合金具有优异的性能,随着关键应用技术的不断发展,其应用潜力巨大。本文简要说明了镁合金的分类,介绍了一些常用合金化元素,如Al、Zn、Mn、Si、Ca、Zr和RE等元素对镁合金性能的影响及机理。这些合金元素单独或共同影响着镁合金组织和性能。

Magnesium alloys have excellent properties. These would widely used in various fields as the key applications technology develop constantly. This paper describes classification of magnesium alloys.The strengthening effect and mechanism by adding alloying elements, such as Al, Zn,Mn,Si,Ca,Zr and RE are introduced. These alloying elements individually or collectively affect the mierostrueture and properties of magnesium alloys.
