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>"}],"date_created":"2025-05-15T06:59:28Z","publisher":"Materials Research Forum LLC","title":"Advanced thermomechanical flow forming: A novel approach to α’-martensite control for enhanced material properties","quality_controlled":"1","year":"2025","department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"user_id":"36287","_id":"59907","type":"conference","status":"public","editor":[{"first_name":"Pierpaolo","full_name":"Carlone, Pierpaolo","last_name":"Carlone"},{"first_name":"Luigino","last_name":"Filice","full_name":"Filice, Luigino"},{"first_name":"Domenico","last_name":"Umbrello","full_name":"Umbrello, Domenico"}],"volume":54,"author":[{"last_name":"Arian","full_name":"Arian, Bahman","id":"36287","first_name":"Bahman"},{"last_name":"Homberg","full_name":"Homberg, Werner","id":"233","first_name":"Werner"},{"full_name":"Kersting, Lukas","last_name":"Kersting","first_name":"Lukas"},{"first_name":"Ansgar","last_name":"Trächtler","id":"552","full_name":"Trächtler, Ansgar"},{"last_name":"Rozo Vasquez","full_name":"Rozo Vasquez, Julian","first_name":"Julian"},{"full_name":"Walther, Frank","last_name":"Walther","first_name":"Frank"}],"date_updated":"2025-10-30T13:55:08Z","oa":"1","doi":"10.21741/9781644903599-127","conference":{"name":"The 28th International ESAFORM Conference on Material Forming - ESAFORM 2025","start_date":"2025-05-06","end_date":"2025-05-09","location":"Paestum, Italy"},"main_file_link":[{"url":"https://mrforum.com/product/9781644903599-127/","open_access":"1"}],"publication_identifier":{"issn":["2474-395X"]},"has_accepted_license":"1","publication_status":"published","intvolume":"        54","citation":{"ieee":"B.
