ժҪ 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 ��3 and other low-��CSL (coincident site lattice) boundaries are lowest for the steel annealed for 120 s. Segregation of phosphorus is also found at low angle grain boundaries.
