摘要

研究了变形温度、变形速度对铸轧AZ31镁合金板的极限拉深比（LDR）和组织的影响。变形温度在250

00℃之间

铸轧AZ31镁合金板的极限拉深比（LDR）可达2.5。低的变形速度有利于提高拉深性能。低温条件下

拉深变形后的组织主要为孪晶;随着温度的增加

拉深过程中发生再结晶

在晶界周围产生细小的再结晶晶粒。

Abstract

The effect of deformation temperature and deformation speed on the limit drawing ratio （LDR） and microstructure of the roll-casting AZ31 magnesium alloy sheet. The limit drawing ratio （LDR） of the roll-casting AZ31 magnesium alloy sheet reaches 2.5 when the deformation temperature is between 250℃ and 300 ℃. Low drawing speed benefits the enhancement of the drawing performance. The microstructure after drawing deformation is mainly twins. With the increasing of the temperature

the recrystallization occurs during the drawing deformation and there are many refine recrystallized grains around the grain boundaries.
