概要
- 論文の詳細を見る
Extruded and cast plates of AZ type magnesium alloys were successfully joined by friction stir welding (FSW). The effects of FSW conditions on the formation of defects were revealed in relation to tool rotation speed and specimen travel speed. Magnesium alloys with higher aluminum contents became difficult to be joined and the optimum condition without defect was restricted in a narrow condition range. The structure of the stirred zone was a fine-grained recrystallized structure even in the case of cast AZ91D. FSW joints had better mechanical properties than those of GTA welded joints. In particular the toughness of the stirred zone increased more than that of the base metal.
