Abstract

In this study, we are aimed for the thread rolling processing at room temperature of extruded magnesium alloy. We focused attention to torsion working as means to achieve this purpose. When torsion is applied to extruded magnesium alloy held with chucks at a fixed distance, the material is especially strengthened and fined grains on the surface. Moreover, the randomizing of the crystal orientation is urged. Grain structure on the surface of specimen can be partially controlled by annealing. It aims improving thread rolling workability at room temperature of magnesium alloys have poor ductility by using this characteristic. Thus, it was shown that thread rolling workability at the room temperature is improved by the torsion working. However, the forming of the thread has not been solved yet complete. The thread rolling processing conditions and the annealing processing condition were examined. And, the external observation and mechanical properties of the screw were investigated.
