摘要

研究了热处理工艺对AZ31镁合金轧制板材的显微组织和力学性能的影响。试验表明

AZ31镁合金轧制板材在退火过程中发生了静态再结晶现象

200℃时可以观察到再结晶现象

再结晶温度为200～250℃。分析了退火温度和退火时间对合金显微组织、晶粒尺寸、硬度以及力学性能的影响规律。

Abstract

Influence of annealing on tensile strength and microstructure of AZ91 magnesium alloy was investigated.Experimental results show that the occurrence of static recrystallization in magnesium alloy sheet during annealing can be observed

which begins at annealing of 200 ℃

while its recrystallization temperature of the alloys is in range of 200 ℃ to 250 ℃.The influencing mechanism of annealing temperature and annealing time on the microstructure

grain size

hardness and mechanical properties of the alloy sheet was approached.
