Abstract

Due to the increasing importance of reducing CO2 emissions, lightweight construction

strategies are highly emphasized in the automotive industry. One of these strategies is

lightweight moulding, which is used, for example, in the space frame design. Here, lightweight

materials are joined with castings to form a structure that is well adapted to the application of

force. Especially for multi-material joints, self-piercing riveting is frequently used as joining

technology due to the wide range of joining possibilities and the high load-bearing capacities.

However, the susceptibility of cast aluminium alloys to cracking due to the brittle microstructure

causes great challenges for mechanical joining by self-piercing riveting. Therefore, this study

investigates the suitability of the cast aluminium alloy AlSi9Mn for self-piercing riveting.

Various improvement strategies are utilized to increase suitability considering of joining as well

as material parameters. An evaluation of the joint and its damage characteristics is provided by

metallographic analysis and industrial X-ray computed tomography (XCT). Metallographic

analysis is used to determine the quality relevant characteristics of the joint, while XCT provides

volumetric and non-destructive testing of the joint for internal cracks.
