Friction-based Injection Clinching Joining (F-ICJ) is a new advanced staking joining technology for lightweight hybrid structures. This PhD work was devised to understand the fundamental scientific and engineering aspects of F-ICJ. The joint formation mechanisms, process-related changes in the joined materials, and quasi-static mechanical behavior were clarified. This knowledge was used to establish relationships between processing conditions, microstructure, and global joint properties. A proof of concept of the F-ICJ process was explored by optimizing the mechanical performance in coupon level, and providing an initial assessment of scaling up to a multi-spot subcomponent.
