  text: <jats:p>Abstract. 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>
