Electromagnetic riveting (EMR) technology had unique connection advantages compared to traditional riveting methods. The influence of EMR process on microstructures and mechani- cal properties for 2A10 and 6082 aluminum riveted structures was investigated by comparison with regular pressure riveting (RPR) process. The microstructures and mechanical properties of the two riveting processes were analyzed by optical microscopy and tensile testing machine, respectively. The micro-hardness and the interference amount were also investi- gated. The results showed that the main characteristic of the driven head was the shear zone. The grain deformation of the EMR in shear zone was more severe than that of the RPR. The width of the shear zone of the RPR was larger than that of the EMR. The trend of micro- hardness distribution was opposite along the direction of the shear zone. Meanwhile, the distribution of the interference amounts of EMR had a better uniformity. The failure mecha- nisms of shear tests of the EMR and RPR were same, but the pull-out tests were different. The dynamic loading had a great influence on the microstructures and mechanical properties of riveted structures, and the mechanical properties of EMR were significantly enhanced.
