Magnesium alloy sheets have an increasing proportion of applications in automobiles due to their high specific strength. The usability of traditional welding processes and mechanical joining processes is restricted by the characteristic of magnesium alloy sheets. In order to improve the plasticity of magnesium alloy sheets and realize the reliable joining of magnesium alloy sheets with dissimilar sheets, researchers have conducted a lot of research. In this paper, the existing joining processes of friction stir spot welding, friction stir blind riveting, hybrid self-piercing riveting, and friction self-piercing riveting for magnesium alloy sheets are reviewed; the latest advances of joining process are introduced; and the principle, development, advantages, and shortcomings of each process for improving the plasticity of magnesium alloy sheets are systematically described. Several unaddressed issues in the joining of magnesium alloy sheets are identified. The hybrid of mechanical and solid-state joining processes will be a trend in future development.

“…Previous studies show that a joint may look good externally, but microcomputed tomography reveals some internal cracking in the same joint. 18,19 In order to determine the operating envelope of the SPR process and products for any given combination of materials, it is critical to develop a deeper understanding of the deformation behaviour of the materials and rivet during the joining process. It is also necessary to relate the deformation characteristics to residual stress distribution.…”

The feasibility of measuring residual stresses in self-pierce riveted (SPR) joints by neutron diffraction technique was investigated. The main challenge involved dealing with the very small dimensions of SPR joints. Two different joints were examined: aluminium-steel and steel-steel. Even though small dimensions were involved, meaningful results were obtained. In the rivet head, tensile stress was observed for the steel-steel sample, whereas only compressive stress was observed for the aluminium-steel. The residual stress in the rivet head was higher at the centre and lower at the edge for both joints. Stresses in the sheet material beside the rivet wall and at a distance of three times the rivet radius from the rivet axis were not significant. For the SPR joints examined, the maximum value of residual stress was compressive and occurred in the rivet leg. The results are discussed according to the physical events involved during the process.
