Mechanical joints are traditionally analyzed through destructive micrograph analysis, which may compromise internal geometry and morphology, as evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast, industrial X-ray computed tomography (XCT) offers a non-destructive method for component diagnosis, providing volumetric insights without damaging the sample and enabling dimensional measurement. The DFG-funded Collaborative Research Center TRR 285 is exploring XCT's application in assessing mechanical joinability across various joining processes and materials, particularly in multi-material systems like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material compositions, leading to artifacts that complicate interface detection. This research aims to validate XCT for joint investigations, yielding quantitative characteristics that surpass those from traditional micrograph analysis.","lang":"eng"}],"department":[{"_id":"43"},{"_id":"157"}],"user_id":"44935","_id":"60439","project":[{"grant_number":"418701707","name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"145","name":"TRR 285 – C01: TRR 285 - Subproject C01"},{"name":"TRR 285 – C03: TRR 285 - Subproject C03","_id":"147"},{"name":"TRR 285 – C02: TRR 285 - Subproject C02","_id":"146"},{"_id":"149","name":"TRR 285 – C05: TRR 285 - Subproject C05"}],"language":[{"iso":"eng"}]},{"date_created":"2024-06-07T09:38:45Z","author":[{"last_name":"Borgert","full_name":"Borgert, Thomas","id":"83141","first_name":"Thomas"},{"last_name":"Nordieker","id":"88725","full_name":"Nordieker, Ansgar Bernhard","first_name":"Ansgar Bernhard"},{"last_name":"Homberg","full_name":"Homberg, Werner","id":"233","first_name":"Werner"}],"publisher":"Materials Research Forum LLC","date_updated":"2025-09-22T05:45:37Z","conference":{"name":"ESAFORM 2024","location":"Toulouse"},"doi":"10.21741/9781644903131-180","title":"Form-based manufacturing of aluminium and steel auxiliary joining elements as the basis for an efficient joining operation","publication_status":"published","publication_identifier":{"issn":["2474-395X"]},"citation":{"apa":"Borgert, T., Nordieker, A.

Reducing the weight of vehicles can significantly lower the energy or fuel consumed and thus the emissions during operation. One possibility to assess this is the use of a property adapted multi-material systems containing high strength steel, light metals like aluminium or magnesium and fibre reinforced plastics. While expanding the number of materials used new challenges arise for the production and furthermore the joining technology to manufacture the vehicle made of the multi-material systems. One approach to overcome these challenges is to use innovative and adaptable joining techniques which allows the manufacturing of joints of different material combinations. Extensive research activities on the two stage thermo-mechanical joining process with adaptable joining elements was able to demonstrate the great potentials in terms of joining dissimilar materials with good strength. The previously kinematic and path-based fabrication of auxiliary joining elements is modified in this publication to a form-based approach with a perspective of establishing an efficient process chain using easily and cheaply available rods. Based on the new approach to produce the auxiliary joining elements, it can be demonstrated that a reproducible production of the geometry is possible for the investigated steel as well as aluminium material. </jats:p>"}]},{"date_updated":"2025-09-22T05:44:28Z","publisher":"Elsevier BV","volume":9,"author":[{"last_name":"Borgert","full_name":"Borgert, Thomas","id":"83141","first_name":"Thomas"},{"id":"88725","full_name":"Nordieker, Ansgar Bernhard","last_name":"Nordieker","first_name":"Ansgar Bernhard"},{"first_name":"Eugen","last_name":"Wiens","full_name":"Wiens, Eugen","id":"7888"},{"last_name":"Homberg","id":"233","full_name":"Homberg, Werner","first_name":"Werner"}],"date_created":"2024-06-07T09:31:59Z","title":"Investigations to improve the tool life during thermomechanical and incremental forming of steel auxiliary joining elements","doi":"10.1016/j.jajp.2024.100185","publication_identifier":{"issn":["2666-3309"]},"publication_status":"published","year":"2024","intvolume":"         9","citation":{"bibtex":"@article{Borgert_Nordieker_Wiens_Homberg_2024, title={Investigations to improve the tool life during thermomechanical and incremental forming of steel auxiliary joining elements}, volume={9}, DOI={<a href=\"https://doi.org/10.1016/j.jajp.2024.100185\">10.1016/j.jajp.2024.100185</a>}, number={100185}, journal={Journal of Advanced Joining Processes}, publisher={Elsevier BV}, author={Borgert, Thomas and Nordieker, Ansgar Bernhard and Wiens, Eugen and Homberg, Werner}, year={2024} }","mla":"Borgert, Thomas, et al. “Investigations to Improve the Tool Life during Thermomechanical and Incremental Forming of Steel Auxiliary Joining Elements.” <i>Journal of Advanced Joining Processes</i>, vol. 9, 100185, Elsevier BV, 2024, doi:<a href=\"https://doi.org/10.1016/j.jajp.2024.100185\">10.1016/j.jajp.2024.100185</a>.","short":"T.

In order to analyse the failure development in detail, the specimens are investigated using in-situ computed tomography (in-situ CT). Here, the tensile-shear test is interrupted at points of interest and CT scans are conducted under load. In addition, the interrupted in-situ testing procedure is validated by comparing the loading behaviour with conventional continuous tensile-shear tests.

Requirements of multi-material construction involve adjustments to standard joining techniques.

Furthermore, the friction-induced heat of the novel joining process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy. In particular, the eutectic Si is more fine-grained, resulting in higher joint ductility. This study indicates the joining suitability of a hypoeutectic aluminium casting alloy in combination with adaptive manufactured additional joining elements.

In order to reduce global energy consumption in production and industry along with the associated CO2 emissions, existing resources must be used more efficiently. This includes the energy-efficient and comprehensive recycling of a wide range of metals. Especially for the production of aluminium, there is a large potential for saving energy using efficient recycling processes. With regard to the recycling of aluminium studies have shown that solid-state recycling processes are significantly more efficient considering the used energy and resources compared to the conventional, smelting-metallurgical recycling process. In this paper, the direct and energy-efficient friction-induced recycling process (FIRP) based on the conform process is further described and analysed in terms of the temperature-property relationships. For this purpose, the influence of the processing temperature on the microstructure and properties of the recycled semi-finished products is investigated using the toll system that enables an ECAP forming. Specific sections of the (in theory) infinite, recycled semi-finished product are taken and analysed at different process temperatures of the solid state recycling process. Based on these sections, the properties in terms of mechanical hardness, strength, ductility and grain size are analysed and a degressive relationship between process temperature and mechanical hardness up to a temperature of 270 °C can be shown. Applying the Hall-Petch relationship, it is analysed whether there is a correlation between the strength and the microstructure in the form of the grain size. </jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","type":"conference","language":[{"iso":"eng"}],"keyword":["Recycling","Aluminium","Friction-Induced","Energy Efficiency"],"department":[{"_id":"156"}],"user_id":"83141","_id":"44036"},{"publication_identifier":{"issn":["2504-4494"]},"publication_status":"published","intvolume":"         7","citation":{"ieee":"T.

One example of a highly adaptable process due to the two-step process sequence is thermomechanical joining with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to the joint. In this paper, the potentials of the adaption in the two-stage joining process with aluminium auxiliary joining elements are investigated. To this end, it is first investigated whether a thermomechanical forming process can be used to achieve a uniform and controlled manufacturing regarding the process variable of the temperature as well as the geometry of the FSJC. Based on the successful proof of the high and good repeatability in the FSJC manufacturing, possibilities, and potentials for the targeted influencing of the process and FSJC geometry are shown, based on an extensive variation of the process input variables (delivery condition and thus mechanical properties of the raw parts as well as the process parameters of rotational speed and feed rate).

In order to achieve the energy-saving and climate targets, it is not only necessary to develop new processes and processing possibilities, but also to optimise known process chains with regard to energy and resource efficiency in the area of production technology. Here, the recycling of supposed production waste represents an opportunity to save energy. In addition to the conventional and smelting metallurgical recycling process, extensive research activities have therefore been carried out for alternative solid-state recycling processes. One example is the friction-induced recycling process, which has been used in past studies to demonstrate the energy- and resource-efficient production of semi-finished products from aluminium scrap such as chips. In addition, properties like chemical composition and strength can be adjusted locally and in terms of processing time. This can be used to improve the versatility of further processing steps."}],"user_id":"83141","department":[{"_id":"156"}],"project":[{"name":"TRR 285 – C03: TRR 285 - Subproject C03","_id":"147"}],"_id":"46752","language":[{"iso":"eng"}]},{"year":"2023","issue":"6","quality_controlled":"1","title":"Potentials of a friction-induced recycling process to improve resource and energy efficiency in manufacturing technology","date_created":"2023-10-02T06:59:53Z","publisher":"Springer Science and Business Media LLC","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Efforts to enhance sustainability in all areas of life are increasing worldwide. In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group \"Light—Efficient—Mobile\" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process.</jats:p>"}],"publication":"International Journal of Material Forming","language":[{"iso":"eng"}],"keyword":["General Materials Science"],"citation":{"apa":"Borgert, T., Milaege, D., Schweizer, S., Homberg, W., Schaper, M., &#38; Tröster, T.

In order to increase the sustainability of forming processes it would be favorable if the forming of workpieces becomes possible using production waste. At the Chair of Forming and Machining Technology of the Paderborn University (LUF) research is presently conducted with the overall goal to produce workpieces directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based forming processes like friction spinning (or cognate processes) are used due to their high efficiency. As a pre-step, the production of semi-finished parts was the subject of accorded research work at the LUF. Therefore, a friction-based hot extrusion process was used for the full recycling or rework of aluminum chips into profiles. Investigations of the recycled semi-finished products show that they are comparable to conventionally produced semi-finished products in terms of dimensional stability and shape accuracy. An analysis of the mechanical properties of hardness and tensile strength shows that a final product with good and homogeneously distributed properties can be produced. Furthermore, significant correlations to the friction spinning process could be found that are useful for the above-mentioned direct part production from secondary aluminum.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Metals","title":"Friction-Induced Recycling Process for User-Specific Semi-Finished Product Production","doi":"10.3390/met11040663","date_updated":"2023-04-26T13:25:52Z","date_created":"2021-04-20T05:02:14Z","author":[{"full_name":"Borgert, Thomas","id":"83141","last_name":"Borgert","first_name":"Thomas"},{"last_name":"Homberg","full_name":"Homberg, Werner","first_name":"Werner"}],"year":"2021","citation":{"mla":"Borgert, Thomas, and Werner Homberg. “Friction-Induced Recycling Process for User-Specific Semi-Finished Product Production.” <i>Metals</i>, 663, 2021, doi:<a href=\"https://doi.org/10.3390/met11040663\">10.3390/met11040663</a>.","bibtex":"@article{Borgert_Homberg_2021, title={Friction-Induced Recycling Process for User-Specific Semi-Finished Product Production}, DOI={<a href=\"https://doi.org/10.3390/met11040663\">10.3390/met11040663</a>}, number={663}, journal={Metals}, author={Borgert, Thomas and Homberg, Werner}, year={2021} }","short":"T.
