摘要

通过拉伸试验

OM（光学显微镜）

SEM（扫描电镜）

XRD

TEM（透射电镜）等

研究了变质剂Nd和C2Cl6单独变质处理和复合变质处理对AZ91镁合金组织和性能的影响。结果表明

3种变质处理均能起到细化组织、提高性能的效果

其中Nd单独变质效果最好

C2Cl6变质效果次之

Nd与C2Cl6复合变质的效果最差。

Abstract

Effects of Nd or C2Cl6modification and Nd and C2Cl6compound modification on the microstructure and mechanical properties of AZ91magnesium alloy were investigated by tensile testing

OM（optical microscopy）

SEM（scanning electron microcopy）

XRD（X-ray diffraction）and TEM（transmission electron microscopy）.The results show that the three modification ways can refine the microstructure and improve properties of the AZ91magnesium.Nd exhibits the most desirable effects

and then C2Cl6

while Nd and C2Cl6composite inoculation exhibits the worst.
