| Abstract | ||
| In this study, the performance of polyvinyl butyral interlayered friction stir welded (PVBFSWed) and ultrasonic vibration-assisted friction stir welded (UVaFSWed) AA7075-T651 joints are investigated, considering the effect of tool rotation and welding speed. The joints' tensile strength, microhardness, microstructure, and fracture behavior are evaluated. The UVaFSWed joints showed better performance compared to the PVBFSWed joints. The highest tensile strength of 322.8 MPa and microhardness of 157 Hv in weld nugget is observed for the UVaFSWed joint at a tool rotation of 2000 rpm and welding speed of 40 mm/min. However, the lowest surface roughness of 7.98 | ||
