Abstract：

The temperature distribution of sheet is affected by different heating methods. Meanwhile, the temperature difference appears in the different positions of sheet，which resulting in material internal performance difference. In view of the above problems, the magnesium alloy sheets were heated by two overall heating methods of carbon fiber electric pipe heating and hot air heating, and the influences of heating methods and forming temperature on the formability of magnesium alloy sheet and the mechanical properties of its formed parts were studied by forming variable-angle cone parts and square cone parts with constant forming angle. The results show that in the forming temperature range of 150-275 ℃, the formability of magnesium alloy sheet is enhanced with the increasing of forming temperature. When the forming temperature is 250 ℃, the magnesium alloy sheet has better formability, and its formed parts also obtain the best mechanical properties. At the same forming temperature, the magnesium alloy sheet heated by carbon fiber electric pipe heating has better formability, and its formed parts also have better mechanical properties.
