摘要

开发了一种适合重力铸造的Mg-Al-Zn-Mn系镁合金

并研究了其力学性能与成分之间的关系

找出最优化的合金成分Mg-9Al-0.8Zn-0.3Mn

经T6工艺热处理后

Abstract

The relation between the mechanical properties and chemical compositions of self-developed Mg-Al-Zn-Mn series Mg alloy suitable for gravity casting was investigated to have determined the optimized composition Mg-9Al-0.8Zn-0.3Mn alloy.The mechanical properties of the T6 heat treated Mg alloy at ambient temperature are as follows: tensile strength σ

=270 MPa

yield strength σ

0.2

=162 MPa and elongation δ=3.88%.The changes of mechanical properties and microstructural characteristics of the Mg alloy after T6 heat treatment were compared with those of untreated ones.
