摘要

研究了异步轧制路径对AZ31镁合金板材的金相组织和性能的影响。结果表明

以每道次轧制方向旋转180°而板正法向不变的路径轧制时

板材的金相显微组织较好

晶粒细小（约为20μm）

孪晶少

伸长率达到26%

并且板材的屈服强度、应变硬化指数较高;而按每道次板材轧制方向和板正法向均旋转180°的路径轧制时

板材的塑性应变比值最大。这说明异步轧制路径对AZ31镁合金性能的影响是比较复杂的

应该综合考虑异步轧制工艺条件的影响

通过工艺优化提高异步轧制AZ31镁合金板材的冲压成形能力。

Abstract

Effects of asynchronous rolling routes on microstructure and properties of AZ31 magnesium alloy sheets have been described. The results show that the microstructure of the sheets with fine grain about 20μm in grain size and little twin crystal can be observed

and the elongation of the sheets reach 26% with higher yield strength and strain-hardening index when it is rolled with rotating direction of 180°per pass and the constant normal direction

while the maximum plastic strain ratio can be observed when it is rolled with rotating direction of 180°both per pass and normal direction

showing complicate effects of asynchronous rolling routes on properties of the magnesium alloy sheets. The comprehensive effects of asynchronous rolling routes should be fully considered and optimized to improve the drawability of AZ31 magnesium alloy sheets.
