Abstract Macro-texture of decarburized specimens of conventional grain oriented electrical steels with MnS particles as inhibitors was determined by XRD technology. The microscopic texture and misorientation distribution between Goss grains and the other surrounding grains were analyzed after the decarburized specimens were heated up to 925 . The misorientation environment for different oriented grains of primary texture in the decarburized specimen was calculated based on the misorientation principles. Both experimental observations and theoretical calculations indicated the high angle characteristics of the misorientation between Goss grains and the surrounding grains, especially in the angle range of 30o to 45o. However, low angle misorientation was more emphasized arround non-Goss grains. Goss grains are still mainly surrounded by high angle gain boundaries after secondary recrystallization.
