| Outline of Final Research Achievements |
The crystal orientation of AZ31B and AZ91D magnesium alloy was randomized by torsion working. It was succeed that high quality M8 screw was fabricated by the optimum back-torsion working preliminary thread rolling at room temperature. The distribution of hardness in as thread-rolled AZ91D magnesium alloy screw was modified to uniform distribution by the isothermal aging treatment at 423K for 460.8ks.
