Abstract Scope |
To meet energy reduction goals, new lightweight multimaterials are being used for automotive and transportation industries. Current joining methods for automotive industries involve clinching or a steel self-pierce rivet, with the latter introducing a recyclability challenge. To address the challenges associated with joining dissimilar metals and respective recyclability of automotive components, we introduce high velocity riveting (HiVe), a dynamic joining technique that forms a metallurgical bond in solid phase while simultaneously forming a mechanical interlock. Aluminum alloys AA6061-T6 and AA5052-H32 were bonded utilizing varying die geometries along with dissimilar DP590 steel to aluminum material stacks. Advanced electron microscopy and x-ray tomography were used to investigate the bonding interfaces and determine the influence of the process parameters on joint performance. Lapshear testing of HiVe joints resulted in up to 500% increase in max loading and up to 72% increase in elongation compared clinching of comparable material stacking. |
