| Abstract Scope |
Friction stir interlocking (FSI) and rotating hammer riveting (RHR) are emerging dissimilar material joining processes demonstrating hybrid features of mechanical fastening and lap welding, simultaneously. In these techniques, shear processing is used to integrate magnesium rivets/pins into a joint assembly. Riveting using magnesium was previously challenging owing to the its low workability at room temperature. In this presentation, an introduction to these processes and their advantages in joining metal and polymer plates will be demonstrated. Focus will be placed on the microstructural evolution of the components during processing and the micro-to-mesoscale features that are critical for ideal joint performance. Mechanical performance of FSI and RHR joints will be evaluated and contrasted with currently available industry standards. Finally, the importance of such processes in the context of developing reliable dissimilar high-specific-strength material joints for achieving lightweighting without compromising component performance and safety in the automotive industry will be presented. |
