Dissimilar lap-shear joints were fabricated by the friction stir blind riveting process using AA6111 (0.9 mm) as the top-sheet and AA6022 (2.0 mm) as the bottom-sheet in a 2-sheet stack-up. Tensile testing of the friction stir blind riveting joints exhibited a combined fracture mode of initial shear followed by tearing. The maximum tensile load of the friction stir blind riveting joints increases slightly with increasing feed rate and shows little dependence on the spindle speed. The microhardness of the material at different layers along with the rivet penetration are analyzed and discussed.
