This paper presents a new tool and process design with a driven tool for the targeted adjustment of residual stress distributions in the friction-spinning process. 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. Residual stress depth distributions are measured with the incremental hole-drilling method. The workpieces (tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW 6060 T6) tubular profiles. It is shown that the residual stress depth distributions change significantly due to the new process designs, which offers new potentials for the targeted adjustment of residual stresses that serve to improve the workpiece properties.</jats:p>","lang":"eng"}],"date_created":"2022-07-25T08:32:43Z","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"journal_article","department":[{"_id":"156"}]},{"issue":"10","publication":"Materials Testing","abstract":[{"text":"For a reliable, strength-compliant and fracture-resistant design of components and technical structures and for the prevention of damage cases, both the criteria of strength calculation and fracture mechanics are essential.

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.

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.

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."}],"publication":"Materials Science and Engineering: A","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"type":"journal_article","department":[{"_id":"158"},{"_id":"321"}],"date_created":"2022-02-11T17:19:11Z","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":[{"last_name":"Reitz","orcid":"0000-0001-9047-467X","first_name":"Alexander","full_name":"Reitz, Alexander","id":"24803"},{"full_name":"Grydin, Olexandr","first_name":"Olexandr","last_name":"Grydin","id":"43822"},{"first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko","id":"43720"}],"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"}],"quality_controlled":"1","citation":{"apa":"Reitz, A., Grydin, O., &#38; Schaper, M.

Due to plastic deformation of metastable austenitic steel, phase transformation from γ-austenite into α’-martensite occurs. This is initiated by the formation of shear bands as product of the external stresses. By means of coupled microscopic and micromagnetic investigations, a characterization of the microstructure was carried out. In particular, this study shows the distribution of the strain-induced α’-martensite and its influence on material properties like hardness at different depths. The microstructural analyses by means of electron backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite (ca. 23 %) close to the outer specimen surface, where the plastic deformation and the direct contact with the forming tool take place. In the middle area (ca. 1.5 mm depth from the outer surface), the portion of transformed α’-martensite drops to 7 % and in the inner surface to 2 %. These results are well correlated with microhardness and micromagnetic measurements at different depths. EBSD and atomic force microscopy (AFM) were used to make a detailed characterization of the topography and degree of deformation of the shear bands. Likewise, the mechanisms of nucleation of α’-martensite were discussed. This research contributes to the development of micromagnetic sensors to monitor the evolution of properties during flow forming. This makes them more suitable for closed-loop property control, which offers possibilities for an application-oriented and more efficient production.</jats:p>"}],"date_created":"2022-11-04T08:29:21Z","keyword":["Metals and Alloys","Mechanics of Materials","Condensed Matter Physics","Electronic","Optical and Magnetic Materials"],"type":"journal_article","department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"title":"Coupled microscopic and micromagnetic depth-specific analysis of plastic deformation and phase transformation of metastable austenitic steel AISI 304L by flow forming","year":"2022","publication_identifier":{"issn":["2195-8599","0032-678X"]},"author":[{"full_name":"Rozo Vasquez, Julian","first_name":"Julian","last_name":"Rozo Vasquez"},{"first_name":"Hanigah","last_name":"Kanagarajah","full_name":"Kanagarajah, Hanigah"},{"id":"36287","last_name":"Arian","first_name":"Bahman","full_name":"Arian, Bahman"},{"full_name":"Kersting, Lukas","first_name":"Lukas","last_name":"Kersting"},{"last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner","id":"233"},{"id":"552","full_name":"Trächtler, Ansgar","last_name":"Trächtler","first_name":"Ansgar"},{"full_name":"Walther, Frank","last_name":"Walther","first_name":"Frank"}],"publication_status":"published","date_updated":"2023-05-02T08:19:27Z","intvolume":"        59","language":[{"iso":"eng"}],"doi":"10.1515/pm-2022-0064"},{"title":"Innovative Online Measurement and Modelling Approach for Property-Controlled Flow Forming Processes","year":"2022","publication_identifier":{"issn":["1662-9795"]},"author":[{"last_name":"Kersting","first_name":"Lukas","full_name":"Kersting, Lukas"},{"last_name":"Arian","first_name":"Bahman","full_name":"Arian, Bahman","id":"36287"},{"first_name":"Julian Rozo","last_name":"Vasquez","full_name":"Vasquez, Julian Rozo"},{"id":"552","full_name":"Trächtler, Ansgar","last_name":"Trächtler","first_name":"Ansgar"},{"id":"233","last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner"},{"first_name":"Frank","last_name":"Walther","full_name":"Walther, Frank"}],"date_updated":"2023-05-02T08:19:13Z","publication_status":"published","intvolume":"       926","language":[{"iso":"eng"}],"doi":"10.4028/p-yp2hj3","publication":"Key Engineering Materials","abstract":[{"lang":"eng","text":"<jats:p>The production of complex multi-functional, high-strength parts is becoming increasingly important in the industry. Especially with small batch size, the incremental flow forming processes can be advantageous. 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.</jats:p>"}],"date_created":"2022-11-04T08:27:33Z","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"journal_article","department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"status":"public","page":"862-874","publisher":"Trans Tech Publications, Ltd.","_id":"33999","user_id":"36287","volume":926,"citation":{"apa":"Kersting, L., Arian, B., Vasquez, J.

Proactive change management of requirement changes yields the potential to handle such changes efficiently. A systematic approach is required for proactive change management to assess and reduce the risk of a requirement change with appropriate effort in industrial application. Within the paper at hand, a novel method for Proactive Management of Requirement Changes (ProMaRC) is presented. It is developed in close collaboration with industry experts and evaluated based on workshops, pilot users’ feedback, three industrial case studies from the automotive industry and five development projects from research. To limit the application effort, an automated approach for dependency analysis based on the machine learning technique BERT and semi-automated assessment of change likelihood and impact using a modified PageRank algorithm is developed. Applying the method, the risks of requirement changes are assessed systematically and reduced by means of proactive change measures.

Recently, grafted perfect vortex beams (GPVBs) have attracted much attention due to their unique optical properties and potential applications. However, the current method to generate and manipulate GPVBs requires a complex and bulky optical system, hindering further investigation and limiting its practical applications. 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."}],"issue":"30","publication":"Advanced Materials","type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"date_created":"2022-06-20T11:05:50Z","publication_status":"published","date_updated":"2023-05-12T11:20:44Z","article_type":"original","intvolume":"        34","title":"Multichannel Superposition of Grafted Perfect Vortex Beams","year":"2022","publication_identifier":{"issn":["0935-9648","1521-4095"]},"author":[{"full_name":"Ahmed, Hammad","first_name":"Hammad","last_name":"Ahmed"},{"full_name":"Intaravanne, Yuttana","first_name":"Yuttana","last_name":"Intaravanne"},{"first_name":"Yang","last_name":"Ming","full_name":"Ming, Yang"},{"last_name":"Ansari","first_name":"Muhammad Afnan","full_name":"Ansari, Muhammad Afnan"},{"full_name":"Buller, Gerald S.","first_name":"Gerald S.","last_name":"Buller"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","id":"30525"},{"full_name":"Chen, Xianzhong","last_name":"Chen","first_name":"Xianzhong"}],"doi":"10.1002/adma.202203044","article_number":"2203044","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"ieee":"H.
