The {111}∥ND plane texture,grain boundary characterization and grain boundary segregation of phosphorus are investigated for the phosphorus added high strength interstitial free(IF)steel annealed at 810℃ for 60 s to 180 s.The results show that the maximum volume fraction of {111}∥ND plane texture is about 85% and the grain boundary segregation peak of phosphorus is about 14 at.%for the steel annealed at 810 ℃ for 120 s.The Σ3 and other low-ΣCSL(coincident site lattice)boundaries are lowest for the steel annealed for 120 s.Segregation of phosphorus is also found at low angle grain boundaries.
