Influence of welding thermal cycle on grain structure of 5083 aluminum alloy weld by friction stir welding

2 mm thick 5083 aluminum alloy was butt welded by FSW, and defect-free welded joints were obtained. The effect of the welding thermal cycle on the grain structure of the weld was studied by OM and EBSD. The results show that with the increase in the friction stir tool rotation speed, the strain rate...
