| Abstract: | This study investigates the strain-induced martensitic transformation (SIMT) and springback behavior of 304 austenitic stainless steel during multi-pass roll forming. By utilizing cyclic tensile tests, quantitative X-ray diffraction (XRD), and electron backscatter diffraction (EBSD), we established a critical correlation between microstructural evolution and macroscopic mechanical response. The martensite volume fraction increased monotonically with the cumulative forming angle. A significant acceleration in transformation kinetics was observed at a 40 deg forming angle, coinciding with a rapid decrease in twin boundary density and widespread slip band activation, and the extensive nucleation of martensite in 304 stainless steel triggers the transformation-induced plasticity (TRIP) effect, effectively suppressing springback. Mechanistic analysis revealed that α′-martensite nucleation sites evolved from high-energy twin boundaries to slip bands within soft-oriented grains as deformation progressed, while strictly adhering to the Kurdjumov–Sachs orientation relationship. Furthermore, the biaxial stress state characteristic of roll forming promoted a higher transformation rate compared to uniaxial tension. These findings provide a critical microstructural basis for accurate springback prediction in metastable stainless steels. [ABSTRACT FROM AUTHOR] |
