Friction stir spot welding (FSSW) was implemented to joining of AA2024-T4 and commercially pure copper with SiC nanoparticles as a reinforcing particle with different rotational speeds (1300, 1600, and 1900 rpm) and dwell times (2, 4, and 6 s). For this purpose, macro- and microstructures, shear ten...
