PURPOSE: A method for increasing fatigue strength of magnesium alloy processing materials is provided to prevent the reduction of strength by removing twin crystal in a material by applying pre-tension of 1~10% to an magnesium alloy extruding or rolling material. CONSTITUTION: A method for increasing fatigue strength of magnesium alloy processing materials is as follows. A magnesium alloy processing material is pre-tensioned. Twin crystal of 10~12 existing in the magnesium alloy processing material is removed through pre-tensile stress. The pre-tensile stress is performed in a strain rate of 1~10%. |
