本文采用扫描电镜、透射电镜观察了Zn—27wt%Al合金的铸态组织及其120℃的时效组织,测定了120℃时效过程中硬度随时效时间变化的关系曲线,分析了性能变化与组织转变之间的关系。
In this paper, the as-cast microstructure and the aging microstructure of Zn-27wt% Al alloy were observed by scanning electron microscopy and transmission electron microscopy. The relationship between the hardness and the aging time at 120 ℃ was measured. The relationship between.
