text: Lightweight design is a driving concept in modern automotive engineering to
minimize resource consumption over a vehicle's lifecycle through multi-material
design, which relies on the use of joining techniques in car body fabrication.
Multi-material design and the increasing trend towards producing large structural
components using the megacasting process pose considerable challenges, particularly
in the mechanical joining of aluminium-silicon (AlSi) castings. These castings
typically exhibit low ductility and are prone to cracking when mechanically joined.
Based on the excellent castability of hypoeutectic AlSi alloys, these are applied
in sand casting and die casting as well as in megacasting. With a silicon content
between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that
initiates cracks during mechanical joining. To enhance the joinability of castings,
the research hypothesis is that improved solidification conditions enable a significant
modification in the microstructure and therefore, increase the mechanical properties.
During the manufacture of the castings using the sand casting process, the solidification
conditions within the structural elements are varied to modify the microstructure
to obtain castings with graded microstructure. The castings are evaluated using
mechanical, microstructural and joining testing methods and finally, a microstructure-joinability
correlation is established.
