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. The\r\npurpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby\r\nimproving versatility." article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Pia Katharina full_name: Kaimann, Pia Katharina id: '44935' last_name: Kaimann - first_name: Ina full_name: Stratmann, Ina last_name: Stratmann - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Johann Moritz Benedikt full_name: Klöckner, Johann Moritz Benedikt last_name: Klöckner - first_name: Moritz full_name: Mann, Moritz last_name: Mann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Neuser M, Kaimann PK, Stratmann I, et al.

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. article_number: '01081' article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Malte Christian full_name: Schlichter, Malte Christian id: '61977' last_name: Schlichter - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Neuser M, Schlichter MC, Hoyer K-P, Bobbert M, Meschut G, Schaper M.

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." article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Pia Katharina full_name: Holtkamp, Pia Katharina id: '44935' last_name: Holtkamp - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Fabian full_name: Kappe, Fabian id: '66459' last_name: Kappe - first_name: Safak full_name: Yildiz, Safak last_name: Yildiz - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Neuser M, Holtkamp PK, Hoyer K-P, et al.

Lightweight design is one of the central topics of the automotive industry since reducing mass can save emissions over the entire life cycle of a component. Nowadays, vehicle structures usually consist of a multi-material design, which poses the additional challenge of joining these different materials. Mechanical joining is the most common way of joining different types of materials. Cast aluminium alloys of the AlSi system have a low ductility, which causes cracks during the mechanical joining process in the joint. One research approach is to achieve a fine microstructure by influencing the solidification rate since this results in increased mechanical properties, specifically the elongation at fracture and yield strength. A very fine microstructure can be achieved by utilizing Twin-roll casting (TRC) which is a continuous casting process in which high solidification rates of more than 100 K/s occur. In this study, the hypoeutectic cast aluminium alloy AlSi9 is processed in the TRC process using copper rollers. The cast strips are investigated regarding the microstructure-property correlation. A variation of the roller materials and cooling conditions allows for an increase in the solidification rate, whereby a defined, fine microstructure can be achieved, which enhances the mechanical properties of the hypoeutectic aluminium casting alloys. author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Neuser M, Hoyer K-P, Schaper M.

Twin-Roll-Casting (TRC) is an energy- and cost-efficient process to produce near-net-shape aluminum strips. Due to the high affinity of molten aluminum to steel surfaces, those rollers show signs of wear throughout the rolling campaign. This leads to the necessity of restoring the worn surfaces to suitable parameters. The easiest way is to grind the surface till all superficial defects are omitted. However, the thickness of the roller is not endless, therefore the rollers must be replaced after a certain amount of surface reconditioning. This ultimately leads to the non-usability of the roller. This research shows a route to recondition the surface including the possibility of renewing worn-down surfaces with an energy- and cost-efficient high-velocity oxygen fuel (HVOF) treatment with subsequent grinding to the desired initial surface parameters. author: - first_name: Martin full_name: Lauth, Martin id: '13858' last_name: Lauth - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Winfried full_name: Gräfen, Winfried last_name: Gräfen citation: ama: 'Lauth M, Hoyer K-P, Schaper M, Gräfen W.

Addressing these requires a systematic understanding of the interactions between feedstock, process parameters, and final part characteristics throughout the entire production chain. This study presents results from a comprehensive interlaboratory investigation conducted by 32 research institutions, evaluating six feedstock, including nanoparticle‐modified aluminum alloy and polyamide powders, under standardized protocols. Data analysis encompasses 69 powder properties, 15 process parameters per print, and 78 part features, culminating in a dataset of over 1.2 million correlations. Advanced statistical methods and machine learning are employed to identify critical variability drivers, such as the impact of nanoparticle modifications on powder flowability and thermal conductivity, as well as the influence of process parameters on reproducibility. Newly introduced dimensionless figures of merit provide universal metrics to describe and predict thermal and mechanical interactions, simplifying process optimization and material characterization. The findings, supported by an open‐access dataset adhering to findable, accessible, interoperable, and reusable principles, advance understanding of material–process–structure–property relationships. They establish a benchmark for future research and lay the foundation for improving the reliability, quality, and sustainability of AM processes. article_number: '2402930' author: - first_name: Ihsan Murat full_name: Kuşoğlu, Ihsan Murat last_name: Kuşoğlu -

Unfortunately, studies investigating this alloy showed that additively produced samples exhibit anisotropic microstructures. This anisotropy compromises the mechanical properties and complicates the loading state in the implant. Moreover, the minimum requirements as specified per designated standards such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional heat treatment. As this route requires energy, infrastructure, labor, and expertise, which in turn mean time and money, many of the additive manufacturing benefits are negated. Thus, the goal of this work was to achieve better isotropy by applying only adapted additive manufacturing process parameters, specifically focusing on the build orientations. In this work, samples orientated in 90°, 45°, and 0° directions relative to the building platform were manufactured and tested. These tests included mechanical (tensile and fatigue tests) as well as microstructural analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography were correlated with the acquired mechanical properties. These showed that 90°-aligned samples performed best under fatigue load and that all requirements specified by the standard regarding monotonic load were met. article_number: '117' author: - first_name: Dennis full_name: Milaege, Dennis id: '35461' last_name: Milaege - first_name: Niklas full_name: Eschemann, Niklas last_name: Eschemann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Milaege D, Eschemann N, Hoyer K-P, Schaper M.

This can be overcome by using twin-roll casting to produce thin sheets. Further thermomechanical treatment, including hot or cold rolling, and heat treatment can adjust the mechanical properties of twin-roll cast Al-Li sheets. The whole manufacturing chain requires detailed knowledge of the precipitation and dissolution behavior during heating, soaking and cooling, to purposefully select any process parameters. This study shows the process chain of a twin-roll cast Al–Cu–Li alloy achieving a hardness of around 180 HV1 by adapting the heat treatment parameters for homogenisation, hot rolling and age hardening. Both hardness and microstructure evolution are visualised along the process chain. author: - first_name: Sina full_name: Mallow, Sina last_name: Mallow - first_name: Jette full_name: Broer, Jette last_name: Broer - first_name: Benjamin full_name: Milkereit, Benjamin last_name: Milkereit - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Kai-Uwe full_name: Garthe, Kai-Uwe id: '11199' last_name: Garthe orcid: 0000-0003-0741-3812 - first_name: Dennis full_name: Milaege, Dennis id: '35461' last_name: Milaege - first_name: Viktoriya full_name: Boyko, Viktoriya last_name: Boyko - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Olaf full_name: Kessler, Olaf last_name: Kessler citation: ama: Mallow S, Broer J, Milkereit B, et al.

To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational modelling of auxetic and non-auxetic stents was performed in this study to minimise or even avoid these deposition agents in the future. Computational modelling was performed in unrestricted (open) conditions and restricted (in an artery) conditions. Finally, stent designs were produced by additive manufacturing, and mechanical testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit very little foreshortening and radial recoil in unrestricted deployment conditions compared to non-auxetic stent 3. However, stent 2 shows structural instability (strut failure) during unrestricted deployment conditions. For the restricted deployment condition, stent 1 shows a higher radial recoil compared to stent 3. In the tensile test simulations, short elongation for stent 1 due to strut failure is demonstrated, whereas no structural instability is noticed for stent 2 and stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening of the struts of the stents resulting in short elongations during tensile testing compared to the simulations (stent 2 and stent 3). A modelling framework for the stent deployment system that enables the selection of appropriate stent designs before in vivo testing is required. This leads to the acceleration of the development process and a reduction in time, resulting in less material wastage. The modelling framework shall be useful for doctors designing patient-specific stents. article_number: '1592' author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Dennis full_name: Milaege, Dennis last_name: Milaege - first_name: Maxwell full_name: Hein, Maxwell id: '52771' last_name: Hein orcid: 0000-0002-3732-2236 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Pramanik S, Milaege D, Hein M, Hoyer K-P, Schaper M.

This, in turn, requires an adaptation of standard joining techniques. In multi-material combinations, the importance of integral cast components, in particular, is increasing and poses additional technical challenges for the industry. One approach to solve these challenges is adaptable joining elements manufactured by a thermomechanical forming process. By applying an incremental and thermomechanical joining process, it is possible to react immediately and adapt the joining process inline to reduce the number of different joining elements. In the investigation described in this publication, cast plates made of the cast aluminium alloy EN AC-AlSi9 serve as joining partners, which are processed by sand casting. The joining process of hypoeutectic AlSi alloys is challenging as their brittle character leads to cracks in the joint during conventional mechanical joining. To solve this, the frictional heat of the novel joining process applied can provide a finer microstructure in the hypoeutectic AlSi9 cast alloy. In detail, its Si is finer-grained, resulting in higher ductility of the joint. This study reveals the thermomechanical joining suitability of a hypoeutectic cast aluminium alloy in combination with adaptively manufactured auxiliary joining elements. article_number: '169' article_type: original author: - first_name: Thomas full_name: Borgert, Thomas id: '83141' last_name: Borgert - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Borgert T, Neuser M, Hoyer K-P, Homberg W, Schaper M.

Here, a mixture of pure Fe and atomised 316L steel powder is used for PBF-LB to induce a chemical composition gradient in the microstructure. Optical microscopy and μ-CT investigations proved that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS measurements show the chemical composition gradient leading to the formation of a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition is homogeneous throughout the microstructure. A moderate decrease (1060 to 985 MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment. However, the total elongation of the as-built and heat-treated samples remains the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307 HV1 is observed upon heat treatment. author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Anatolii full_name: Andreiev, Anatolii id: '50215' last_name: Andreiev - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Jan Tobias full_name: Krüger, Jan Tobias id: '44307' last_name: Krüger orcid: 0000-0002-0827-9654 - first_name: Florian full_name: Hengsbach, Florian last_name: Hengsbach - first_name: Alexander full_name: Kircheis, Alexander last_name: Kircheis - first_name: Weiyu full_name: Zhao, Weiyu last_name: Zhao - first_name: Jörg full_name: Fischer-Bühner, Jörg last_name: Fischer-Bühner - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Pramanik S, Andreiev A, Hoyer K-P, et al.

This study could lead to the successful processing of squirrel cage conductors (a lattice structure by design) of an induction motor by additive manufacturing in the future.\r\n\r\n\r\nDesign/methodology/approach\r\nThe compression behaviour of two lattice structures where struts are arranged in a face-centred cubic position and vertical edges (FCCZ), and struts are placed at body-centred cubic (BCC) positions, prepared by laser powder bed fusion (LPBF), is explored. The experimental investigations are supported by finite element method (FEM) simulations.\r\n\r\n\r\nFindings\r\nThe FCCZ lattice structure presents a peak in the stress-strain curve, whereas the BCC lattice structure manifests a plateau. The vertical struts aligned along the compression direction lead to a significant increase in the load-carrying ability of FCCZ lattice structures compared to BCC lattice structures. This results in a peak in the stress-strain curve. However, the BCC lattice structure presents the bending of struts with diagonal struts carrying the major loads with struts near the faceplate receiving the least load. A high concentration of geometrically necessary dislocations (GNDs) near the grain boundaries along cell formation is observed in the microstructure.\r\n\r\n\r\nOriginality/value\r\nTo the best of the authors’ knowledge, this is the first study on additive manufacturing of Fe-3Si lattice structures. Currently, there are no investigations in the literature on the manufacturability and mechanical properties of Fe-3Si lattice structures.\r\n" author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Pramanik S, Hoyer K-P, Schaper M.
