摘要

To examine the effects of different loading directions on mechanical behaviors and dynamic recrystallization of AZ31 magnesium alloy. Uniaxial hot compression experiments were conducted on the original AZ31Mg alloy at 0°, 15°, 30°, 45°, 60°, 75°, and 90° directions on the ND–RD plane. The results show that the sample compressed in the RD direction has a higher degree of dynamic recrystallization, and tensile twins promote the dynamic recrystallization behavior during the hot compression process. There are very few residual twins in the deformed samples. The compression behavior of samples with different orientations on the ND–RD plane shows anisotropy. The yield strength of the samples decreases first and then increases with the increase of the angle. The mechanical behavior of samples with different orientations shows anisotropy. The dynamic recrystallization mechanism of the samples is not affected by the spatial orientation. The dynamic recrystallization mechanism of the 0°, 45°, and 90° samples is all continuous dynamic recrystallization.
