摘要

The widely used ferritic stainless steel (FSS) 0Cr17 undergoes microstructural control through recrystallization annealing. This study develops a 3D phase field model for recrystallization in a polycrystalline material with second phase particles, incorporating the stored energy due to cold deformation and grain orientations. Simulation results show that higher cold-rolling reduction and annealing temperature refine recrystallized grains and narrow their size distribution, whereas increased particle content further refines the grains and size fluctuation. Elevated reduction and temperature accelerate recrystallization kinetics, while particles retard it via enhanced Zener drag. Recrystallized texture evolution is explored using the reverse comparison analysis method. It clarifies that the formation probabilities of recrystallized textures in 0Cr17 FSS are 60% for γ texture at γ/γ and γ/α GBs and 40% for α texture at α/α GBs after annealing at 1153 K following 80% cold reduction. These findings provide quantitative texture-design rules for recrystallization annealing.
