Abstract：

Isothermal bending technology(IBT) of magnesium alloy AZ31 sheet was numerically simulated, and its deformation property and flow rule were analyzed. Therefore, the reasonable deformation parameters were determined with radius of punch 8 mm and distance between two punches 38 mm. Then, the isothermal bending experiment device for magnesium alloy AZ31 sheet was designed and manufactured. The isothermal bending experiments of magnesium alloy AZ31 sheet were carried out at different deformation temperatures, and its microstructure and properties were analyzed. After magnesium alloy AZ31 sheet was deformed by IBT, its elongation was up to 17.1% at room temperature, while the elongation of initial magnesium alloy sheet was only 12.4%. Thus, the former increased by 42% more than the latter.
