Microstructure evolution and mechanical properties of double-sided friction stir welded AZ31B Mg alloy
AZ31 magnesium alloy was welded by double-sided friction stir welding (FSW) in this study. The different rotation directions of the upper tool were adopted during double-sided FSW. The results showed that different rotation directions generated different joint structures. After double-sided FSW, the effects of the different tool rotation direction and welding parameters on microstructure, especially microtexture, and mechanical properties were evaluated.
