“…Whereas, currently, aluminium casting alloys are not industrially processed. The advantage of the processing of aluminium casting alloys in the TRC process results from the fact that a very fine microstructure can be achieved due to the high solidification rate, which enables a rather high ductility [23]. In addition, the TRC process allows for the production of strips with a lower energy input [15,24].…”

Multi-material designs (MMD) are more frequently used in the automotive industry. Hereby, the combination of different materials, metal sheets, or cast components, is mechanically joined, often by forming joining processes. The cast components mostly used are high-strength, age-hardenable aluminium alloys of the Al–Si system. Here, the low ductility of the AlSi alloys constitutes a challenge because their brittle nature causes cracks during the joining process. However, by using suitable solidification conditions, it is possible to achieve a microstructure with improved mechanical and joining properties. For this study, we used the twin-roll casting process (TRC) with water-cooled rollers to manufacture the hypoeutectic AlSi10Mg for the first time. Hereby, high solidification rates are realisable, which introduces a microstructure that is about four times finer than in the sand casting process. In particular, it is shown that a fine microstructure close to the modification with Na or Sr is achieved by the high solidification rate in the TRC process without using these elements. Based on this, the mechanical properties increase, and especially the ductility is enhanced. Subsequent joining investigations validate the positive influence of a high solidification rate since cracks in joints can be avoided. Finally, a microstructure-property-joint suitability correlation is presented.

“…In the study of Haga et al [15], a hypereutectic aluminium alloy was processed. Hypoeutectic aluminium alloys have only been successfully processed in the work of Neuser et al [23]. For this application, the authors processed an AlSi9 alloy on the same caster with steel rolling elements as used in this study.…”
