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.","lang":"eng"}],"author":[{"full_name":"Neuser, Moritz","id":"32340","last_name":"Neuser","first_name":"Moritz"},{"id":"61977","full_name":"Schlichter, Malte Christian","last_name":"Schlichter","first_name":"Malte Christian"},{"last_name":"Hoyer","full_name":"Hoyer, Kay-Peter","id":"48411","first_name":"Kay-Peter"},{"first_name":"Mathias","full_name":"Bobbert, Mathias","id":"7850","last_name":"Bobbert"},{"first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","id":"32056","full_name":"Meschut, Gerson"},{"first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper"}],"volume":408,"oa":"1","date_updated":"2026-02-24T13:41:58Z","main_file_link":[{"url":"\thttps://doi.org/10.1051/matecconf/202540801081","open_access":"1"}],"doi":"10.1051/matecconf/202540801081","conference":{"start_date":"2025-06-02","name":"44th Conference of the International Deep Drawing Research Group (IDDRG 2025)","location":"Lissabon (Portugal)","end_date":"2025-06-05"},"publication_status":"published","citation":{"chicago":"Neuser, Moritz, Malte Christian Schlichter, Kay-Peter Hoyer, Mathias Bobbert, Gerson Meschut, and Mirko Schaper. “Mechanical Joinability of Microstructurally Graded Structural Components Manufactured from Hypoeutectic Aluminium Casting Alloys.” 44th Conference of the International Deep Drawing Research Group (IDDRG 2025) 408 (2025). https://doi.org/10.1051/matecconf/202540801081.","ieee":"M.

As a widely used sheet metal in clinched joints within the automotive industry, the aluminum alloy EN AW-6014 has been the focus of numerous studies. High-cycle fatigue (HCF) is a critical aspect when assessing the durability of clinched joints. In the present work, the HCF behavior of EN AW-6014 T4 was explored both experimentally and numerically. To model the fatigue behavior, Lemaitre’s two-scale damage model was used. Two key parameters, damage strength and damage exponent, are necessary for numerical investigations of HCF behavior. These parameters were determined through experiments with flat specimens and subsequently validated within a numerical model of clinched joints. The numerical results for fatigue match the experimental ones of the clinched joints quite well.","lang":"eng"}],"status":"public","date_updated":"2026-02-24T13:43:56Z","publisher":"Materials Research Forum LLC","volume":52,"author":[{"first_name":"Chin","full_name":"Chen, Chin","last_name":"Chen"},{"first_name":"Malte Christian","last_name":"Schlichter","full_name":"Schlichter, Malte Christian","id":"61977"},{"full_name":"Harzheim, Sven","last_name":"Harzheim","first_name":"Sven"},{"first_name":"Martin","full_name":"Hofmann, Martin","last_name":"Hofmann"},{"first_name":"Mathias","last_name":"Bobbert","id":"7850","full_name":"Bobbert, Mathias"},{"full_name":"Meschut, Gerson","id":"32056","orcid":"0000-0002-2763-1246","last_name":"Meschut","first_name":"Gerson"},{"first_name":"Thomas","full_name":"Wallmersperger, Thomas","last_name":"Wallmersperger"}],"date_created":"2025-04-15T11:14:53Z","title":"High-cycle fatigue testing and parameter identification for numerical simulation of aluminum alloy EN AW-6014","doi":"10.21741/9781644903551-23","quality_controlled":"1","publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","year":"2025","intvolume":" 52","citation":{"chicago":"Chen, Chin, Malte Christian Schlichter, Sven Harzheim, Martin Hofmann, Mathias Bobbert, Gerson Meschut, and Thomas Wallmersperger. “High-Cycle Fatigue Testing and Parameter Identification for Numerical Simulation of Aluminum Alloy EN AW-6014.” In Materials Research Proceedings, Vol. 52.

Firstly, the reuse of products, individual parts and material reduces the need for new production or generation and the associated consumption of energy and resources. Secondly, it helps to avoid the generation of waste. Early consideration of circular economic principles in product development processes is essential to specifically promote reuse, reparability and recycling. Efficient recycling of assemblies requires well-defined strategies. However, various challenges hinder the efficiency of technical recycling processes in industrial applications. This paper presents an Ishikawa (fishbone) diagram-based approach to systematically identify and categorize these influences. The method is implemented within an industrial framework, highlighting key obstacles such as material composition, design constraints, use of technology, framework conditions, economic limitations and regulatory challenges. By applying a scenario analysis, this approach examines potential future developments and their impact on recycling-oriented design choices. This helps to identify critical influencing factors and supports the development of resilient and sustainable industrial practices. This framework will serve as the foundation for developing an automated approach to circular design, enabling industries to more effectively integrate sustainability into their processes and adapt to changing environmental demands.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_name":"GCSM_2025_Rohde_updated.pdf","access_level":"closed","file_id":"64617","file_size":333257,"creator":"kathiroh","date_created":"2026-02-24T13:33:47Z","date_updated":"2026-02-24T13:33:47Z"}],"publication":"Safe and Sustainable Value Creation by Design - Proceedings of the 21st Global Conference on Sustainable Manufacturing","conference":{"start_date":"2025-09-10","name":"21st Global Conference on Sustainable Manufacturing (GCSM 2025)","location":"Bologna, Italy","end_date":"2025-09-12"},"main_file_link":[{"open_access":"1"}],"oa":"1","date_updated":"2026-02-24T14:05:50Z","volume":1,"author":[{"first_name":"Katharina","full_name":"Rohde, Katharina","id":"70143","last_name":"Rohde","orcid":"0009-0000-5738-7304"},{"full_name":"Gonzalez, Barbara Fernandez","last_name":"Gonzalez","first_name":"Barbara Fernandez"},{"id":"74585","full_name":"Budde, Finn Lukas","last_name":"Budde","first_name":"Finn Lukas"},{"first_name":"Manuel","id":"44204","full_name":"Ott, Manuel","last_name":"Ott"},{"first_name":"Iryna","id":"95903","full_name":"Mozgova, Iryna","last_name":"Mozgova"},{"last_name":"Mendibe","full_name":"Mendibe, Alain Alonso","first_name":"Alain Alonso"}],"intvolume":" 1","citation":{"apa":"Rohde, K., Gonzalez, B.

V-SPR enables adaptation to changing boundary conditions, such as a change in the material thickness combination, without varying the rivet die combination due to increased punch actuation and the use of multi-range capable rivets [1]. The inner punch first sets the rivet. The outer punch then forms the rivet head to the respective sheet thickness. For this, the rivet requires a hard shank and a ductile rivet head, which is achieved by an inductive local hardening process [2]. Until now, the joint formation of rivets with graded hardness profile has been challenging to estimate in the FEM simulation due to the inhomogeneous material conditions in the rivet. In this study, a method capable of reproducing the experimentally determined hardness levels of rivets in detail is shown. This FE model enables the realistic modelling of the mechanical properties of the rivet on the basis of the hardness profile in order to predict the correct deformation processes and stresses during the riveting process. First, the detailed experimental hardness mapping of the locally heat-treated rivets is transferred into the FE model. The FEM material model can predict the local strength of the rivet based on hardness by scaling the flow curves. To estimate the predictive capability of the FEM model, the joint formation of rivets with different graded hardness profiles is compared experimentally and simulative. Based on the validated model, the influence of different rivet hardness profiles on the joint formation is analysed numerically. By adapting the material model, a high level of correlation between the experiment's joint formation and the simulation can be achieved.","lang":"eng"}],"department":[{"_id":"43"},{"_id":"157"}],"user_id":"7850","_id":"60440","project":[{"_id":"130","name":"TRR 285: TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"}],"language":[{"iso":"eng"}]},{"title":"In situ CT unter Temperatur: Thermokammer für thermoplastische FKV-Fügeprozesse","publisher":"Deutsche Gesellschaft für Materialkunde e.V.

These, however, are unable to detect phenomena immediately during the joining process. For instance, elastic deformations reverse and cracks close after unloading. In situ methods such as the force-displacement evaluation are used to investigate a clinching process, though deviations in the clinch point geometry cannot be derived with this method. To overcome these limitations, the clinching process can be investigated using in situ computed tomography (in situ CT). When investigating the clinching of aluminum parts in in situ CT, the sheet-sheet interface is hardly visible. Earlier investigations showed that radiopaque materials can be applied between the joining parts to enhance the detectability of the sheet-sheet interface. However, the layers cause strong artefacts, break during the clinching process or change the clinch joint’s properties significantly. In this paper, a minimally invasive method to enhance the interface detectability is presented. First, the aluminum oxide layer is removed by etching. Second, the specimen is electroplated with copper or gold, respectively. In some cases, a mask is applied to create a cross-shaped plating pattern. Then, the plated specimen is clinched with a non-plated counterpart and the interface detectability of the clinch points is assessed in CT scans. It is shown that a copper plating of 2.6–4 μm can visualize some parts of the interface, while 7–9 μm is suitable to enhance the detectability of the sheet-sheet interface almost continuously.","lang":"eng"}],"type":"journal_article","publication":"Journal of Nondestructive Evaluation","language":[{"iso":"eng"}],"article_number":"131","article_type":"original","user_id":"114764","project":[{"name":"TRR 285 - Project Area C","_id":"133"},{"_id":"130","name":"TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"_id":"148","name":"TRR 285 - Subproject C04"}],"_id":"61767","citation":{"apa":"Köhler, D., Dargel, A., Troschitz, J., Gude, M., & Kupfer, R.

Recent research indicates that galvanic corrosion can actually enhance the fatigue life of clinched joints. It is then of significant interest to investigate the effects of another corrosion phenomenon, pitting corrosion, on the fatigue behavior of clinched joints. Pitting corrosion occurs in passive metals and can lead to stress concentrations. In the present study, the effects of pitting corrosion are investigated by using Lemaitre’s two-scale fatigue model with a 2D geometry of clinched joints. A slip condition is applied as a boundary condition to simplify the clinched joint model and reduce the computational cost of solving the contact mechanics problem. Additionally, a method to determine the damage strength and the damage exponent used in the two-scale damage model is introduced. Numerical simulations reveal that pitting corrosion reduces the fatigue life of clinched joints, particularly when it occurs on the internal surface in the neck area.","lang":"eng"}],"author":[{"last_name":"Chen","full_name":"Chen, Chin","id":"114741","first_name":"Chin"},{"first_name":"Sven","full_name":"Harzheim, Sven","last_name":"Harzheim"},{"last_name":"Hofmann","full_name":"Hofmann, Martin","first_name":"Martin"},{"first_name":"Thomas","full_name":"Wallmersperger, Thomas","last_name":"Wallmersperger"}],"date_created":"2025-09-10T07:52:43Z","date_updated":"2026-02-24T15:11:39Z","publisher":"Springer Science and Business Media LLC","doi":"10.1007/s00707-025-04234-8","title":"Numerical investigation of the effects of pitting corrosion on high-cycle fatigue of clinched joints","publication_identifier":{"issn":["0001-5970","1619-6937"]},"publication_status":"published","citation":{"ieee":"C.

Several diagnostics were employed to characterize the spray and nanoparticles. \r\nIncreasing DG flow (6 - 12 slm) results in smaller droplet sizes (DS), cooler flame temperatures, shorter high-temperature droplet/particle residence times, and smaller agglomerates in the size range of 5 - 12 nm with narrower primary particle size distribution, corresponding to higher mass fractal dimensions, as supported by TEM and SMPS analysis, resulting in more compact agglomerates. BET and TEM confirmed decreasing primary particle sizes with increasing DG flow. Raman and XRD analyses predominantly identified maghemite, which shows a bimodal distribution of crystallite sizes, while SS1 samples have a greater proportion of larger crystallites.\r\nThe self-preserving size distributions of agglomerates with a geometric standard deviation of 1.5 are reached faster with increasing DG flow. The barrier effect of DG observed in SS1 leads to slower droplet combustion kinetics, higher temperatures, and delayed precursor release, which, along with downstream flow recirculation, result in significantly higher agglomeration rates outside the visible flame. SS2 demonstrates improved atomization, more stable flames, and finer, uniform nanoparticles with less carbonaceous residues (CR). Conversely, SS1 showed broader DS distributions and higher CR levels on the γ-Fe2O3 surface, especially at higher DG flow.\r\nThis work highlights the essential role of DG flow and nozzle geometry in controlling droplet evaporation, flame stability, and nanoparticle growth, offering insights for optimizing SFS and validating numerical models.\r\n","lang":"eng"}],"publisher":"Elsevier BV","date_created":"2026-02-02T11:41:04Z","title":"Influence of dispersion gas flow on the spray characteristics and γ-Fe2O3 nanoparticles formation and properties in reference SpraySyn burners","year":"2025","_id":"63830","user_id":"98419","article_type":"original","article_number":"121992","type":"journal_article","status":"public","date_updated":"2026-02-25T07:45:44Z","oa":"1","author":[{"full_name":"Massopo, Orlando","last_name":"Massopo","first_name":"Orlando"},{"last_name":"Tischendorf","full_name":"Tischendorf, Ricardo","first_name":"Ricardo"},{"full_name":"Gonchikzhapov, Munko","last_name":"Gonchikzhapov","first_name":"Munko"},{"last_name":"Kasper","full_name":"Kasper, Tina","first_name":"Tina"},{"first_name":"Peter","full_name":"Augustin, Peter","last_name":"Augustin"},{"first_name":"Burak","full_name":"Özer, Burak","last_name":"Özer"},{"full_name":"Reddemann, Manuel","last_name":"Reddemann","first_name":"Manuel"},{"first_name":"Reinhold","last_name":"Kneer","full_name":"Kneer, Reinhold"},{"full_name":"Sheikh, Mohammed-Ali","last_name":"Sheikh","first_name":"Mohammed-Ali"},{"first_name":"Aydan Akyildiz","full_name":"Mert, Aydan Akyildiz","last_name":"Mert"},{"full_name":"Wiggers, Hartmut","last_name":"Wiggers","first_name":"Hartmut"},{"last_name":"Schmid","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"volume":470,"main_file_link":[{"open_access":"1"}],"doi":"10.1016/j.powtec.2025.121992","publication_status":"published","publication_identifier":{"issn":["0032-5910"]},"citation":{"ama":"Massopo O, Tischendorf R, Gonchikzhapov M, et al.
