Development of Warm Forging Method for Magnesium Alloy
A new warm forging method for magnesium alloys is proposed by taking their material properties into consideration. Since the ductility of Mg alloys is low at room temperature, the forging operation is conducted in the temperature range of 200-400°C. In the warm forging of Mg alloys, the billet is easily cooled down in the die cavity before the onset of
