摘要
总结了近年来镁合金中加入合金元素来改善镁合金力学性能的研究现状。论述了镁的合金化原理。介绍了在一些常用镁合金中分别加入Sn、Sb、Bi、Pb、Y、Nd、La、Sr、Sc、B、Ca、Si、Zr、Ag、Cd等合金元素对镁合金力学性能的强化效果以及强化机理。认为固溶强化和第二相强化是加入合金元素强化镁合金的主要方式。
The present study of improving the mechanical properties of magnesium alloy by adding other alloying elements is generalized. The strengthening effect and strengthening theory by adding alloying elements such as Sn, Sb, Bi, Pb, Y, Nd, La, Sr, Sc, B, Ca, Si,Zr,Ag and Cd is introduced. It is thought that solution strengthening and second phase strengthening are two main ways for improving mechanical properties of magnesium alloy.
