<p>A process of working a Mg alloy, which has the steps of: (3-1) applying a strain in the X direction to the Mg alloy, while maintaining the temperature of the alloy at a temperature of 473 K or higher, and then lowering the temperature of the alloy; (3-2) applying a strain in the Y direction and then further lowering the temperature of the alloy; and (3-3) applying a strain in the Z direction. After the three steps, one or more of the above steps may be repeated. The process of working a Mg alloy allows the conversion of crystal grains of the Mg alloy to further fine grains, which leads to the production of a Mg alloy having improved formability.</p> |
