Flow forming is recognized for its precision in producing rotationally symmetric components, but the use of metastable austenitic stainless steel (AISI 304L) introduces challenges due to uncontrolled strain-induced α’ martensite formation. Variations in factors such as eccentricity and batch inconsistencies lead to unpredictable microstructural profiles, limiting reproducibility [1,2]. This study addresses these issues by incorporating thermal actuators for cryogenic cooling and induction heating to regulate forming temperatures, enabling control of the α’-martensite content. Experimental investigations demonstrate that local tempering during thermomechanical reverse flow forming produces discernible variations in microstructure, affecting mechanical and magnetic properties [3]. Controlled local adjustments of α’-martensite content allow for customization of properties in seamless tubes, advancing manufacturing capabilities for complex, defect-free components. The results presented demonstrate promising strategies for implementation within the context of closed-loop property control in flow forming.</jats:p>"}],"publication":"Materials Research Proceedings","doi":"10.21741/9781644903599-127","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://mrforum.com/product/9781644903599-127/"}],"intvolume":"        54","publication_status":"published","date_updated":"2025-10-30T13:55:08Z","author":[{"id":"36287","full_name":"Arian, Bahman","last_name":"Arian","first_name":"Bahman"},{"full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner","id":"233"},{"full_name":"Kersting, Lukas","first_name":"Lukas","last_name":"Kersting"},{"id":"552","last_name":"Trächtler","first_name":"Ansgar","full_name":"Trächtler, Ansgar"},{"full_name":"Rozo Vasquez, Julian","first_name":"Julian","last_name":"Rozo Vasquez"},{"last_name":"Walther","first_name":"Frank","full_name":"Walther, Frank"}],"publication_identifier":{"issn":["2474-395X"]},"title":"Advanced thermomechanical flow forming: A novel approach to α’-martensite control for enhanced material properties","year":"2025"},{"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://popups.uliege.be/esaform21/index.php?id=2759"}],"publication_status":"published","date_updated":"2023-05-02T08:27:48Z","author":[{"last_name":"Arian","first_name":"Bahman","full_name":"Arian, Bahman","id":"36287"},{"id":"233","full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner"},{"last_name":"Riepold","first_name":"Markus","full_name":"Riepold, Markus"},{"id":"552","first_name":"Ansgar","last_name":"Trächtler","full_name":"Trächtler, Ansgar"},{"first_name":"Julian","last_name":"Rozo Vasquez","full_name":"Rozo Vasquez, Julian"},{"full_name":"Walther, Frank","last_name":"Walther","first_name":"Frank"}],"publication_identifier":{"isbn":["978-2-87019-302-0"],"eisbn":["978-2-87019-303-7"]},"year":"2021","title":"Forming of metastable austenitic stainless steel tubes with axially graded martensite content by flow-forming","department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"type":"conference","keyword":["Flow-forming","Spinning","Process Strategy","Martensite Content","Property Control","Micromagnetic Measurement","Metastable Austenitic Stainless Steel"],"date_created":"2021-08-23T13:00:35Z","abstract":[{"lang":"eng","text":"One of the main objectives of production engineering is to reproducibly manufacture (complex) defect-free parts. To achieve this, it is necessary to employ an appropriate process or tool design. While this will generally prove successful, it cannot, however, offset stochastic defects with local variations in material properties. Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties. In the project on which this paper is based, the local martensite content of parts is to be adjusted in a highly precise and reproducible manner. The forming process employed is a special, property-controlled flow-forming process. A model-based controller is thus to generate corresponding correction values for the tool-path geometry and tool-path velocity on the basis of online martensite content measurements. For the controller model, it is planned to use a special process or microstructure (correlation) model. The planned paper not only describes the experimental setup but also presents results of initial experimental investigations for subsequent use in the closed-loop control of α’-martensite content during flow-forming."}],"user_id":"36287","_id":"23465","publisher":"ULiège Library","conference":{"name":"24th International Conference on Material Forming - ESAFORM 2021","start_date":"2021-04-14","location":"Liège, Belgium","end_date":"2021-04-16"},"status":"public","oa":"1","place":"Liège","quality_controlled":"1","citation":{"bibtex":"@inproceedings{Arian_Homberg_Riepold_Trächtler_Rozo Vasquez_Walther_2021, place={Liège}, title={Forming of metastable austenitic stainless steel tubes with axially graded martensite content by flow-forming}, publisher={ULiège Library}, author={Arian, Bahman and Homberg, Werner and Riepold, Markus and Trächtler, Ansgar and Rozo Vasquez, Julian and Walther, Frank}, year={2021} }","ama":"Arian B, Homberg W, Riepold M, Trächtler A, Rozo Vasquez J, Walther F.
