摘要

通过光学显微镜（OM）和扫描电镜（SEM）对组织进行分析

研究了不同均匀化退火温度和时间下铸态AZ80镁合金的显微组织

并进行了能谱（EDS）和XRD分析。通过晶粒大小和成分面积的对比确定最佳均匀化退火工艺为410℃×10h。对AZ80镁合金的高温压缩性能和组织变化的研究发现

在300～400℃时

材料性能最好。

Abstract

Effects of different homogenized annealing temperatures and times on microstructure of as-cast AZ80 magnesium alloy were observed by OM（optical microscope）and SEM（scanning electron microscope）

XRD（X-ray diffraction）and EDS（energy dispersive spectrum）.The desirable grain size and constituent area distribution in microstructure can be obtained with homogenizing at 410℃ for 10 hours.Compressive behavior and microstructure evolution of the AZ80 magnesium alloy at high temperatures were investigated.The results show that desirable comprehensive properties of the alloy can be obtained at 300～400℃.
