To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car\r\nbodies that combine different materials that require joining. Given the variety of materials, mechanical joining\r\nprocesses are preferred. Especially the current development of the Giga/Mega-casting process concerning\r\naluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car\r\nproduction, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often\r\nused in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a\r\nsolidification-joining correlation for the SPR process across a range of Si contents and solidification rates.

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."}],"publication":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)"},{"status":"public","type":"journal_article","article_type":"original","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"user_id":"32340","_id":"58807","project":[{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"_id":"136","name":"TRR 285 – A02: TRR 285 - Subproject A02"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"}],"citation":{"apa":"Neuser, M., Holtkamp, P.

In particular, the car body offers several opportunities for weight reduction. Multi-material designs are increasingly being applied to select the most suitable material for the respective load and ultimately achieve synergy effects. For example, aluminium castings are used at the nodes of a spaceframe body. Subsequently, these are joined with profiles to form the bodyshell. To join different materials mechanical joining techniques, such as semi-tubular self-piercing riveting, are deployed. According to the current state of the art, cracks occur in the aluminium castings during the mechanical joining process as a result of the high degree of deformation. Although the aluminium casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent castability. In particular, the ability to cast thin structural parts is enabled by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis study addresses the mechanical joining properties of the near eutectic aluminium casting alloy AlSi12, depending on different microstructures. These are achieved by annealing processes and modifying agents. Through an adapted heat treatment, the previously lamellar morphology can be transformed into a globular morphology, which leads to increased ductility and prevents the formation of cracks during the self-piercing riveting (SPR). The joinability is investigated using different die geometries, whereas the joint formation is analysed regarding crack initiation. To evaluate the increased ductility, microstructural and mechanical tests are performed and finally, a microstructure-joinability correlation is established."}],"publication":"The Journal of Materials: Design and Applications, Part L","language":[{"iso":"eng"}],"keyword":["aluminium","casting","microstructure","joinability","self-piercing riveting"],"year":"2025","quality_controlled":"1","title":"Mechanical properties and joinability of the near-eutectic aluminium casting alloy AlSi12","date_created":"2025-02-24T10:25:31Z","publisher":"Sage Publications"},{"publication_status":"published","publication_identifier":{"issn":["0042-207X"]},"citation":{"ama":"Šlapáková M, Kihoulou B, Veselý J, et al. 3D-structure of intermetallic interface layer in Al–steel clad material. <i>Vacuum</i>. 2023;212. doi:<a href=\"https://doi.org/10.1016/j.vacuum.2023.112043\">10.1016/j.vacuum.2023.112043</a>","ieee":"M.

Preparation of these alloys by twin-roll casting (TRC), which combines rapid metal solidification and subsequent plastic reduction in a single processing step, could improve the properties of the alloys compared to materials prepared by conventional direct-chill casting. A commonly used approach for identifying primary phases is a chemical analysis by energy dispersive spectroscopy (EDS). More accurate results can be achieved by combining the method with diffraction analysis. This process can be considerably simplified in microscopes equipped with automated crystal orientation and phase mapping (ACOM-TEM). Al-Cu-Li-Mg-Zr alloy was prepared by twin-roll casting. A combination of TEM and STEM images with chemical analysis by EDS and ACOM-TEM was used to obtain complex information about phases of boundary primary particles. The efficiency of the individual methods for the phase identification in TRC Al-Li-based alloys is discussed."}],"author":[{"first_name":"Lucia","full_name":"BAJTOŠOVÁ, Lucia","last_name":"BAJTOŠOVÁ"},{"first_name":"Olexandr","id":"43822","full_name":"Grydin, Olexandr","last_name":"Grydin"},{"first_name":"Mykhailo","last_name":"STOLBCHENKO","full_name":"STOLBCHENKO, Mykhailo"},{"last_name":"Schaper","full_name":"Schaper, Mirko","id":"43720","first_name":"Mirko"},{"last_name":"KŘIVSKÁ","full_name":"KŘIVSKÁ, Barbora","first_name":"Barbora"},{"first_name":"Rostislav","full_name":"KRÁLÍK, Rostislav","last_name":"KRÁLÍK"},{"first_name":"Michaela","full_name":"ŠLAPÁKOVÁ, Michaela","last_name":"ŠLAPÁKOVÁ"},{"full_name":"CIESLAR, Miroslav","last_name":"CIESLAR","first_name":"Miroslav"}],"date_updated":"2023-04-27T16:35:42Z","oa":"1","main_file_link":[{"url":"https://www.confer.cz/metal/2022/4437-phase-identification-in-twin-roll-cast-al-li-alloys","open_access":"1"}],"doi":"10.37904/metal.2022.4437","conference":{"end_date":"2022-05-19","location":"Brno","name":"Metal 2022","start_date":"2022-05-18"},"publication_status":"published","publication_identifier":{"issn":["2694-9296"]},"citation":{"mla":"BAJTOŠOVÁ, Lucia, et al. “Phase Identification in Twin-Roll Cast Al-Li Alloys.” <i>METAL 2022 Conference Proeedings</i>, TANGER Ltd., 2022, doi:<a href=\"https://doi.org/10.37904/metal.2022.4437\">10.37904/metal.2022.4437</a>.","short":"L.
