摘要

This study provides a comprehensive analysis of the effects of cold rolling reductions (40–75%) on the deformation mechanisms, texture evolution, recrystallization behavior, and mechanical properties of super ferritic stainless steel (SFSS). The findings reveal that cold rolling deformation causes grain elongation along the rolling direction (RD), with shear bands preferentially nucleating within grains oriented along the γ-fiber ({111}//ND). The primary texture evolves from a mixed α-fiber ({001}//RD) and γ-fiber ({111}//ND) texture during cold rolling to a γ-fiber texture (with peak intensity at {111}<112>)) after annealing and recrystallization strengthening. High-temperature annealing (950°C) activates nucleation via shear-band-assisted recrystallization and subgrain coalescence, resulting in complete recrystallization after 30 min. In the cold rolling stage, dislocation strengthening predominates, whereas during recrystallization, solid-solution strengthening becomes the primary contributor to the material’s strength. The sample subjected to a 75% cold rolling reduction and annealed at 950°C for 30 min achieved a high tensile strength of 563 MPa, a yield strength of (MPa), and notable elongation of 35%.
