摘要

研究了固溶处理、时效处理以及固溶+时效处理对AZ31镁合金电磁连铸锭组织性能的影响。结果表明

铸锭的各种热处理状态对其组织和力学性能均有不同程度的影响。固溶处理后铸锭的硬度与韧性均有所增加;时效处理后铸锭硬度增加

韧性有所下降;固溶+时效处理后铸锭硬度值（HB）达到51.52

冲击吸收功为3.40J。固溶处理下得到了较优化的热处理工艺

铸锭的冲击吸收功值和硬度值（HB）分别达到3.75J和51.60。

Abstract

Effects of solution treatment

aging treatment and solution +aging treatment on microstructure and properties of electromagnetic continuous casting AZ31 magnesium alloy slab were investigated. The results indicate that microstructure and properties of the slab are related to different heat treatment processes. Hardness and ductility of solution treated slab are increased

while hardness of the aged slab is increased with the decrease of ductility. Meanwhile

hardness and impact absorption power of the slab treated by solution + aging treatment reach 51.52 and 3.40J

respectively. The impact absorption power and hardness of slab treated by an optimized heat treatment can reach 3.75J and 51.60

respectively.
