Locally adapted residual stress depth distributions are intended to improve the functionality of the friction-spinning workpieces, e.g. by delaying failure or triggering it in a defined way. The new process designs with the driven tool and a subsequent flow-forming operation are investigated regarding the influence on the residual stress depth distributions compared to those of standard friction-spinning process.

The workpieces (tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW 6060 T6) tubular profiles.

The complex thermomechanical conditions generate non-uniform residual stress distributions. In order to specifically adjust these residual stress distributions, the influence of different process parameters on residual stress distributions in flanges formed by the friction-spinning of tubes is investigated using the design of experiments (DoE) method. The feed rate with an effect of −156 MPa/mm is the dominating control parameter for residual stress depth distribution in steel flange forming, whereas the rotation speed of the workpiece with an effect of 18 MPa/mm dominates the gradient of residual stress generation in the aluminium flange-forming process. A run-to-run predictive control system for the specific adjustment of residual stress distributions is proposed and validated. The predictive model provides an initial solution in the form of a parameter set, and the controlled feedback iteratively approaches the target value with new parameter sets recalculated on the basis of the deviation of the previous run.

The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications.</jats:p>","lang":"eng"}],"status":"public"},{"user_id":"43720","department":[{"_id":"9"},{"_id":"149"},{"_id":"321"},{"_id":"158"}],"_id":"34097","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials","Ceramics and Composites"],"type":"journal_article","publication":"Advanced Composite Materials","status":"public","author":[{"last_name":"Voswinkel","id":"52634","full_name":"Voswinkel, Dietrich","first_name":"Dietrich"},{"first_name":"Jan Andre","last_name":"Striewe","id":"29413","full_name":"Striewe, Jan Andre"},{"first_name":"Olexandr","id":"43822","full_name":"Grydin, Olexandr","last_name":"Grydin"},{"last_name":"Meinderink","orcid":"0000-0002-2755-6514","full_name":"Meinderink, Dennis","id":"32378","first_name":"Dennis"},{"first_name":"Guido","last_name":"Grundmeier","id":"194","full_name":"Grundmeier, Guido"},{"full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper","first_name":"Mirko"},{"full_name":"Tröster, Thomas","id":"553","last_name":"Tröster","first_name":"Thomas"}],"date_created":"2022-11-17T08:05:26Z","publisher":"Informa UK Limited","date_updated":"2023-04-27T16:36:14Z","doi":"10.1080/09243046.2022.2143746","title":"Co-bonding of carbon fibre-reinforced epoxy and galvanised steel with laser structured interface for automotive applications","publication_status":"published","publication_identifier":{"issn":["0924-3046","1568-5519"]},"quality_controlled":"1","citation":{"ama":"Voswinkel D, Striewe JA, Grydin O, et al.

With data obtained by this optical method, the transformation kinetics for every area of interest along the whole measuring length of a flat specimen could be analyzed by the generation of dilatation curves. The benefit of this innovative optical characterization method compared to a dilatometer test is that the experimental effort for the design of a tailored component could be strongly reduced to the investigation of only a few tailored thermo-mechanical processed specimens. Due to the implementation of a strain and/or temperature gradient within the flat specimen, less metallographic samples are prepared for hardness analysis and analysis of the microstructural composition by scanning electron microscopy to investigate the influence of different process parameters. Compared to performed dilatometer tests in this study, the optical method obtained comparable results for the transformation start and end temperatures. For the final design of a part with tailored properties, the optical method is suitable for a time-efficient material characterization.</jats:p>\r\n                <jats:p><jats:bold>Graphical Abstract</jats:bold></jats:p>","lang":"eng"}],"publisher":"Springer Science and Business Media LLC","date_created":"2023-01-12T09:30:12Z","title":"Optical Detection of Phase Transformations in Steels: An Innovative Method for Time-Efficient Material Characterization During Tailored Thermo-mechanical Processing of a Press Hardening Steel","quality_controlled":"1","issue":"8","year":"2022"},{"author":[{"first_name":"Michaela","full_name":"Šlapáková, Michaela","last_name":"Šlapáková"},{"last_name":"Křivská","full_name":"Křivská, Barbora","first_name":"Barbora"},{"first_name":"Klaudia","last_name":"Fekete","full_name":"Fekete, Klaudia"},{"last_name":"Králík","full_name":"Králík, Rostislav","first_name":"Rostislav"},{"id":"43822","full_name":"Grydin, Olexandr","last_name":"Grydin","first_name":"Olexandr"},{"full_name":"Stolbchenko, Mykhailo","last_name":"Stolbchenko","first_name":"Mykhailo"},{"first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper"}],"volume":190,"date_updated":"2023-04-27T16:40:10Z","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S104458032200287X"}],"doi":"10.1016/j.matchar.2022.112005","publication_status":"published","publication_identifier":{"issn":["1044-5803"]},"citation":{"apa":"Šlapáková, M., Křivská, B., Fekete, K., Králík, R., Grydin, O., Stolbchenko, M., &#38; Schaper, M.

The mechanical properties of additively manufactured Ti-6Al-7Nb are evaluated in as-built and heat-treated conditions. Recrystallization annealing (925 °C for 4 h), β annealing (1050 °C for 2 h), as well as stress relieving (600 °C for 4 h) are applied. For microstructural investigation, scanning and transmission electron microscopy are performed. The different microstructures and the mechanical properties are compared. Mechanical behavior is determined based on quasi-static tensile tests and strain-controlled low cycle fatigue tests with total strain amplitudes εA of 0.35%, 0.5%, and 0.8%. The as-built and stress-relieved conditions meet the mechanical demands for the tensile properties of the international standard ISO 5832-11.

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"}],"keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0921-5093"]},"publication_status":"published","intvolume":"       838","citation":{"ama":"Reitz A, Grydin O, Schaper M.

For this, two cellular solids having nested and non-nested structures are designed and additively manufactured via laser powder bed fusion. The primary objective is to design cellular solids which absorb a significant amount of energy upon impact loading without transmitting a high amount of stress into the cellular solids. Therefore, compression testing of the two cellular solids is performed. The nested and non-nested cellular solids show similar energy absorption properties; however, the nested cellular solid transmits a lower amount of stress in the cellular structure compared to the non-nested cellular solid. The experimentally measured strain (by DIC) in the interior region of the nested cellular solid is lower despite a higher value of externally imposed compressive strain. The second objective of this study is to determine the thermal insulation properties of cellular solids. For measuring the thermal insulation properties, the samples are placed on a hot plate; and the surface temperature distribution is measured by an infrared camera. The thermal insulating performance of both cellular types is sufficient for temperatures exceeding 100 °C. However, the thermal insulating performance of a non-nested cellular solid is slightly better than that of the nested cellular solid. Additional thermal simulations predict a relatively higher temperature distribution on the cellular solid surfaces compared to experimental results.

The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications.</jats:p>"}],"language":[{"iso":"eng"}],"keyword":["General Materials Science"],"publication_identifier":{"issn":["1996-1944"]},"publication_status":"published","intvolume":"        15","citation":{"apa":"Abdelaal, O., Hengsbach, F., Schaper, M., &#38; Hoyer, K.-P.
