The Study on the Thermal Formability of AZ31 Magnesium Alloy Sheets

Abstract:

In this paper, according to the characteristics of the sheets of poor plastic at room temperature and good plastic which is significantly increased after heating, the mechanical properties, microstructure evolution, the flow stress, plane anisotropy and fracture mechanism of AZ31 magnesium alloy sheets at high temperature are studied and analyzed, which provide a reliable basis for the stamping processes of the sheets at high temperature. The most suitable heating temperature for deep drawing sheets of AZ31 magnesium alloy are achieved by the hot-stamping test, and the most suitable heating temperature are near to 350°C. The results for the improvement of the hot-formability of AZ31 magnesium alloy sheets at high temperature provide a theoretical basis and new method.
