| 摘 要： | Uniaxial loading tests are performed on 0.8 mm thick sheets of commercial AZ31B magnesium alloy in the temperature range from room temperature to 400 ℃. The microstructures and tensile properties are studied. The results reveal that there are few twins in the deformation microstructures created when deformation occurres in temperatures ranging from room temperature to 100 ℃, and dynamic recrystallization take place at deformation temperatures exceeding 200 ℃. Commercial AZ31B magnesium alloy sheets have a preferable strength and ductility at room temperature. The ductility of the sheets is improved as the deformation temperature increases. Some characteristics of low temperature superplasticity or high strain rate superplasticity exist.
