  abstract     = {{One of the major topics in the modern automotive industry is reducing emissions and increasing the mileage
range. To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the
other hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car
bodies that combine different materials that require joining. Given the variety of materials, mechanical joining
processes are preferred. Especially the current development of the Giga/Mega-casting process concerning
aluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car
production, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy
system's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often
used in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is
used due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the
microstructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for
hypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a
solidification-joining correlation for the SPR process across a range of Si contents and solidification rates. The
purpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby
improving versatility.}},

  abstract     = {{The conduction of structure-borne sound through joints causes energy dissipation. The sound reduction index describes this energy loss as a level decrease in the particle velocity across series-connected damping elements for which the superposition principle applies. This simple model can help to develop a testing method for joints based on this characteristic energy loss. In this paper, this model is experimentally evaluated for multiple in-series clinched aluminium sheets. Samples connected by several clinch points arranged in parallel are investigated experimentally, and the results are discussed.}},
