An intermetallic layer of Al5Fe2 and Al13Fe4 formed at the interface upon annealing above 500 °C. During in-situ annealing in transmission electron microscope, the layer grew towards the steel side of the interface in tongue-like protrusions. A study of furnace-annealed samples revealed, that the bulk growth of the interface phase proceeds towards the aluminium side. The growth towards steel is a surface effect that takes place simultaneously with the bulk growth towards aluminium. At the beginning of the intermetallic layer formation diffusion of Fe into aluminium prevails, afterwards Al atoms diffuse throught the newly formed intermetallic layer towards steel and the whole interface shifts towards aluminium. The kinetics of growth of the intermetallic layer follows parabolic law in both cases, indicating that the growth is governed by diffusion."}],"publication":"Materials Characterization","doi":"10.1016/j.matchar.2022.112005","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S104458032200287X"}],"article_number":"112005","language":[{"iso":"eng"}],"date_updated":"2023-04-27T16:40:10Z","publication_status":"published","intvolume":" 190","article_type":"original","year":"2022","title":"The influence of surface on direction of diffusion in Al-Fe clad material","publication_identifier":{"issn":["1044-5803"]},"author":[{"full_name":"Šlapáková, Michaela","first_name":"Michaela","last_name":"Šlapáková"},{"first_name":"Barbora","last_name":"Křivská","full_name":"Křivská, Barbora"},{"first_name":"Klaudia","last_name":"Fekete","full_name":"Fekete, Klaudia"},{"full_name":"Králík, Rostislav","last_name":"Králík","first_name":"Rostislav"},{"full_name":"Grydin, Olexandr","first_name":"Olexandr","last_name":"Grydin","id":"43822"},{"full_name":"Stolbchenko, Mykhailo","last_name":"Stolbchenko","first_name":"Mykhailo"},{"last_name":"Schaper","first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720"}]},{"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"department":[{"_id":"158"},{"_id":"321"}],"date_created":"2022-02-11T17:19:11Z","abstract":[{"text":"In order to reduce CO2 emissions in the transport sector, the approach of load-adapted components is increasingly being pursued. For the design of such components, it is crucial to determine their resulting microstructure and mechanical properties. For this purpose, continuous cooling transformation diagrams and deformation continuous cooling transformation diagrams are utilized, however, their curves are strongly influenced by the chemical composition, the initial state and especially the process parameters.\r\n\r\nIn this study, the influence of the process parameters on the transformation kinetics is systematically investigated using an innovative characterization method. The experimental setup allowed a near-process analysis of the transformation kinetics, resulting microstructure and mechanical properties for a specific process route with a reduced number of specimens. A systematic investigation of the effects of different process parameters on the microstructural and mechanical properties made it possible to reveal interactions and independencies between the process parameters in order to design a partial heating or differential cooling process. Furthermore, the implementation of two different cooling conditions, representative of differential cooling in the die relief method with tool-contact and non-contact areas, showed that the soaking duration has a significant influence on the microstructure in the non-contact tool area.","lang":"eng"}],"publication":"Materials Science and Engineering: A","doi":"10.1016/j.msea.2022.142780","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S0921509322001885"}],"article_number":"142780","language":[{"iso":"eng"}],"date_updated":"2023-04-27T16:42:08Z","publication_status":"published","intvolume":" 838","article_type":"original","title":"Influence of thermomechanical processing on the microstructural and mechanical properties of steel 22MnB5","year":"2022","publication_identifier":{"issn":["0921-5093"]},"author":[{"id":"24803","orcid":"0000-0001-9047-467X","first_name":"Alexander","last_name":"Reitz","full_name":"Reitz, Alexander"},{"id":"43822","last_name":"Grydin","first_name":"Olexandr","full_name":"Grydin, Olexandr"},{"id":"43720","full_name":"Schaper, Mirko","first_name":"Mirko","last_name":"Schaper"}],"quality_controlled":"1","citation":{"ieee":"A.

This work deals with the overall system behavior and gas dynamics of pillow-plate channels. A pillow-plate channel was placed in the test section of a blow-down wind tunnel working with dry air, and compressible flow phenomena were investigated utilizing conventional and focusing schlieren optics; furthermore, static and total pressure measurements were performed. The experiments supported the assumption that the system behavior can be described through a Fanno–Rayleigh flow model. Since only wavy walls with smooth profiles were involved, linearized gas dynamics was able to cover important flow features within the channel. The effects of the wavy wall structures on pressure drop and Mach number distribution within the flow path were investigated, and a good qualitative agreement with theoretical and numerical predictions was found. The present analysis demonstrates that pressure losses in pillow-plate heat exchangers are rather low, although their strong turbulent mixing enables high convective heat transfer coefficients."}],"date_created":"2023-04-27T16:21:44Z","keyword":["Mechanical Engineering","Energy Engineering and Power Technology","Aerospace Engineering"],"type":"journal_article","department":[{"_id":"145"}],"title":"Flow in Pillow-Plate Channels for High-Speed Turbomachinery Heat Exchangers","year":"2022","publication_identifier":{"issn":["2504-186X"]},"author":[{"first_name":"Stephan","last_name":"Sundermeier","full_name":"Sundermeier, Stephan"},{"full_name":"Passmann, Maximilian","first_name":"Maximilian","last_name":"Passmann"},{"first_name":"Stefan","last_name":"aus der Wiesche","full_name":"aus der Wiesche, Stefan"},{"full_name":"Kenig, Eugeny Y.","last_name":"Kenig","first_name":"Eugeny Y.","id":"665"}],"date_updated":"2023-04-27T16:53:41Z","publication_status":"published","intvolume":" 7","article_number":"12","language":[{"iso":"eng"}],"doi":"10.3390/ijtpp7020012","citation":{"ama":"Sundermeier S, Passmann M, aus der Wiesche S, Kenig EY.

Consequently, the future over dimensioning can be reduced. Furthermore, the improved prediction quality of the joining process simulation leads to an improvement in the simulation of load-bearing capacity as well. In this way, the entire sampling process can be performed virtually without any experimental investigations. This will contribute to the advancement of lightweight construction in the automotive industry. In this work, the frictional behavior is studied in dependence on the local joining process parameters. As a reference for the numerical investigations, clinch joints by means of a die with fixed geometry are joined. Additionally, a hardness mapping is performed on the microsection of the clinch joints. It shows the local strain hardening, which correlates with the forming degree in the simulation. Based on the occurring contacts and the local joining process parameters in the joining process simulation, the test matrix for the experimental friction tests is defined. The friction tests are carried out on a compression-torsion-tribometer. This type of tribometer is able to apply high interface pressures above the initial yield stress due to the specimen encapsulation. Besides, the pure joining part contact, the contact between the joining part and joining tool can be tested as well. The experimental test setup offers the possibility to evaluate the influences of temperature, relative velocity, interface pressure, and frictional stroke independently. Based on the results of the experimental friction tests, a friction model is created. The resulting friction model is integrated into the numerical joining process simulation via a subroutine. To validate the quality of the new friction modeling, the results of simulations are compared with the experiments in terms of load-stroke diagrams, joint geometry, and hardness mappings on the microsection.

Therefore, a new method for determining friction coefficients in sheet metal materials was developed and tested. The aim of this study is the numerical investigation of this experimental method by means of FE simulation. The experimental setup is modelled in a 3D numerical simulation taking into account the process parameters varying in the experiment, such as geometric properties, contact pressure and contact velocity. Furthermore, the contact description of the model is calibrated via the experimentally determined friction coefficients according to clinch-relevant parameter space. It is shown that the assumptions made in the determination of the experimental data in preliminary work are valid.

In general, the conditions in a deep-drawing process change due to changing tribology conditions, varying degrees of spring back, or scattering material properties in the sheet blanks, which affects the resulting pre-strain. Mechanical joining processes, especially clinching, are influenced by these process-related pre-strains. The final geometric shape of a clinched joint is affected to a significant level by the prior material deformation when joining with constant process parameters. That leads to a change in the stiffness and force transmission in the clinched joint due to the different geometric dimensions, such as interlock, neck thickness and bottom thickness, which directly affect the load bearing capacity. Here, the influence of the pre-straining in the deep drawing process on the force distribution in clinch points in an automotive assembly is investigated by finite-element models numerically. In further studies, the results are implemented in an optimization tool for designing clinched components. The methodology starts with a pre-straining of metal sheets. This step is followed by 2D rotationally symmetric forming simulations of the joining process. The resulting mesh of each forming simulation is rotated and 3D models are obtained. The clinched joint solid model with pre-strains is used further to determine the joint stiffnesses. With the simulation of the same test set-up with an equivalent point-connector model, the equivalent stiffness for each pre-strain combination is determined. Simulations are performed on a clinched component to assess the influence of pre-strain and sheet thinning on the clinched joint loadings by using the equivalent stiffnesses. The investigations clearly show that for the selected component, the loadings at the clinch points are dependent on the sheet thinning and the stiffnesses due to pre-strain. The magnitude of the influence varies depending on the quantity considered. For example, the shear force is more sensitive to the joint stiffness than to the sheet thinning."}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s11740-021-01103-w"}],"language":[{"iso":"eng"}],"doi":"10.1007/s11740-021-01103-w","title":"Numerical investigation of the clinched joint loadings considering the initial pre-strain in the joining area","year":"2022","author":[{"id":"38177","full_name":"Martin, Sven","last_name":"Martin","first_name":"Sven"},{"last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman","id":"34782"},{"full_name":"Bobbert, Mathias","first_name":"Mathias","last_name":"Bobbert","id":"7850"},{"id":"553","first_name":"Thomas","last_name":"Tröster","full_name":"Tröster, Thomas"},{"id":"32056","full_name":"Meschut, Gerson","first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246"}],"publication_identifier":{"issn":["0944-6524","1863-7353"]},"publication_status":"published","date_updated":"2023-04-28T11:57:22Z","oa":"1","citation":{"apa":"Martin, S., Bielak, C.

The production of parts with complex geometry and locally graded material properties currently depicts a great challenge in the flow forming process. At this point, the usage of closed-loop control for the shape and properties could be a feasible new solution. The overall aim in this project is to establish an intelligent closed-loop control system for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces in a flow forming process. To reach this goal, a novel sensor concept for online measurements of the wall thickness reduction and the martensite content during forming process is proposed. It includes the setup of a modified flow forming machine and the integration of the sensor system in the machine control. Additionally, a simulation model for the flow forming process is presented which describes the forming process with regard to the plastic workpiece deformation, the induced α’-martensite fraction, and the sensor behavior. This model was used for designing a closed-loop process control of the wall thickness reduction that was subsequently realized at the real plant including online measured feedback from the sensor system.","lang":"eng"}]},{"status":"public","_id":"32869","publisher":"Trans Tech Publications, Ltd.","page":"1457-1467","volume":926,"user_id":"14931","citation":{"chicago":"Stallmeister, Tim, and Thomas Tröster. “In-Mold-Assembly of Hybrid Bending Structures by Compression Molding.” Key Engineering Materials 926 (2022): 1457–67. https://doi.org/10.4028/p-5fxp53.","short":"T.

In this process, the core structure, which is provided with stiffening ribs and functional elements, is formed and joined to two metal belts in one single step. For experimental validation of the concept, the development of a prototypic molding tool and the manufacturing of hybrid beams including process parameters are described. Three-point bending tests and optical measurement technologies are used to characterize the failure behavior and mechanical properties of the produced hybrid beams.

Here, a compact metasurface approach for generating and manipulating GPVBs in multiple channels is proposed and demonstrated, which eliminates the need for such a complex optical setup. A single metasurface is utilized to realize various superpositions of GPVBs with different combinations of topological charges in four channels, leading to asymmetric singularity distributions. The positions of singularities in the superimposed beam can be further modulated by introducing an initial phase difference in the metasurface design. The work demonstrates a compact metasurface platform that performs a sophisticated optical task that is very challenging with conventional optics, opening opportunities for the investigation and applications of GPVBs in a wide range of emerging application areas, such as singular optics and quantum science."}],"language":[{"iso":"eng"}],"article_number":"2203044","doi":"10.1002/adma.202203044","author":[{"full_name":"Ahmed, Hammad","first_name":"Hammad","last_name":"Ahmed"},{"first_name":"Yuttana","last_name":"Intaravanne","full_name":"Intaravanne, Yuttana"},{"first_name":"Yang","last_name":"Ming","full_name":"Ming, Yang"},{"full_name":"Ansari, Muhammad Afnan","last_name":"Ansari","first_name":"Muhammad Afnan"},{"last_name":"Buller","first_name":"Gerald S.","full_name":"Buller, Gerald S."},{"full_name":"Zentgraf, Thomas","first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","id":"30525"},{"full_name":"Chen, Xianzhong","first_name":"Xianzhong","last_name":"Chen"}],"publication_identifier":{"issn":["0935-9648","1521-4095"]},"title":"Multichannel Superposition of Grafted Perfect Vortex Beams","year":"2022","article_type":"original","intvolume":" 34","publication_status":"published","date_updated":"2023-05-12T11:20:44Z"},{"user_id":"23547","volume":9,"_id":"29790","publisher":"Wiley","status":"public","oa":"1","quality_controlled":"1","citation":{"mla":"Kothe, Linda, et al. “Stimulation and Enhancement of Near‐Band‐Edge Emission in Zinc Oxide by Distributed Bragg Reflectors.” Advanced Materials Interfaces, vol. 9, 2102357, Wiley, 2022, doi:10.1002/admi.202102357.","apa":"Kothe, L., Albert, M., Meier, C., Wagner, T., & Tiemann, M.

The reflector stacks are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and 800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis. The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by the photonic structure. When the optical bandgap of the reflector is in resonance with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related emission mode is suppressed.

To assure the clinch point’s quality, the force displacement curve during clinching or the bottom thickness are monitored. The most significant geometrical characteristics of the clinch point, neck thickness and undercut, are usually tested destructively by microsectioning. However, micrograph preparation goes ahead with a resetting of elastic deformations and crack-closing after unloading. To generate a comprehensive knowledge of the clinch point’s inner geometry under load, in-situ computed tomography (CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive to the inner state of the clinch point, it could detect critical events like crack development during loading. If such events are indicated, the loading process is stopped and a stepped in-situ CT of the following crack and deformation development is performed. In this paper, the concept is applied to the process of clinching itself, providing a detailed three-dimensional insight in the development of the joining zone. A test set-up is used which allows a stepwise clinching of two aluminium sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system. In order to minimize X-ray absorption, a beryllium cylinder is used within the set-up frame and clinching tools are made from Si3N4. The actuator and sensor necessary for the TDA are integrated in the set-up. In regular process steps, the clinching process is interrupted in order to perform a TDA and a CT scan. In order to enhance the visibility of the interface, a thin tin layer is positioned between the sheets prior clinching. It is shown, that the test-set up allows a monitoring of the dynamic behaviour of the specimen during clinching while the CT scans visualize the inner geometry and material flow non-destructively."}],"publication":"Key Engineering Materials","department":[{"_id":"157"},{"_id":"43"}],"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"date_created":"2024-02-06T15:04:45Z","intvolume":" 926","publication_status":"published","date_updated":"2025-06-02T20:21:13Z","author":[{"last_name":"Köhler","first_name":"Daniel","full_name":"Köhler, Daniel"},{"full_name":"Stephan, Richard","first_name":"Richard","last_name":"Stephan"},{"last_name":"Kupfer","first_name":"Robert","full_name":"Kupfer, Robert"},{"first_name":"Juliane","last_name":"Troschitz","full_name":"Troschitz, Juliane"},{"last_name":"Brosius","first_name":"Alexander","full_name":"Brosius, Alexander"},{"full_name":"Gude, Maik","last_name":"Gude","first_name":"Maik"}],"publication_identifier":{"issn":["1662-9795"]},"title":"Investigations on Combined <i>In Situ</i> CT and Acoustic Analysis during Clinching","year":"2022","doi":"10.4028/p-32330d","language":[{"iso":"eng"}],"project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"citation":{"mla":"Köhler, Daniel, et al. “Investigations on Combined <I>In Situ</I> CT and Acoustic Analysis during Clinching.” Key Engineering Materials, vol. 926, Trans Tech Publications, Ltd., 2022, pp. 1489–97, doi:10.4028/p-32330d.","bibtex":"@article{Köhler_Stephan_Kupfer_Troschitz_Brosius_Gude_2022, title={Investigations on Combined <i>In Situ</i> CT and Acoustic Analysis during Clinching}, volume={926}, DOI={10.4028/p-32330d}, journal={Key Engineering Materials}, publisher={Trans Tech Publications, Ltd.}, author={Köhler, Daniel and Stephan, Richard and Kupfer, Robert and Troschitz, Juliane and Brosius, Alexander and Gude, Maik}, year={2022}, pages={1489–1497} }","ama":"Köhler D, Stephan R, Kupfer R, Troschitz J, Brosius A, Gude M.
