摘要：
AA7075 aluminum and Q235 steel were successfully joined by self-riveting friction stir lap welding (SR-FSLW). The pre-drilled holes of Q235 were filled by AA7075, achieving the self-riveting process. In addition, the AA7075 rivets were locked by the aluminum/steel swirl-layered structure, and the swirl-layered structure consisted of fine grains and intermetallic compounds layers due to the mechanical and metallurgical impacts of SR-FSLW. A cyclic flow of AA7075 was observed inside the rivets, and a plunging-squeezing-filling-locking model was proposed to illustrate the formation mechanism of locked rivets. Compared with the traditional FSLW joint, the shear tensile properties of SR-FSLW joint were significantly enhanced. Moreover, enlarging the diameter of pre-drilled hole contributed to the increment in the effective sheet thickness, strengthening the SR-FSLW joint further. All FSLW/SR-FSLW joints were failed in the nugget zone of AA7075 side, and a mixture of ductile-brittle fracture was observed due to the existence of aluminum/steel hook.
