Abstract
In order to alleviate the formation of stress concentration, cracks and edge of rivets holes induced by the high loading force and loading speed during traditional electromagnetic riveting (EMR) process, a new riveting process of friction forge riveting (FFR) was first proposed to connect 6061-T6 aluminum alloy and TA2 titanium through TA2 rivets. Furthermore, surface formation, microstructures and joint performances of the FFR joint were studied. The results show that with the increase of rotating speed, the volume of driven rivet head increases. The structure and hardness of the joint shows an annular distribution, and an adiabatic shear band (ASB) is formed. In tensile shear tests, the FFR joint experiences two times of fracture successively, and belongs to the mixed fracture of toughness and brittleness. The hardness values on both sides of ASB vary greatly, where is also the location of tensile fracture.
