The microstructure evolved after the initial stage of abnormal grain growth (AGG) in Fe-3 wt%Si steel was examined using synchrotron X-ray microdiffraction to identify the sub-boundaries, which had been suggested to induce the selective AGG of Goss-oriented grains. The splitting of Laue diffraction peaks caused by sub boundaries was observed only in Goss grains and not in matrix grains in the entire samples. The sub boundaries were measured to have very low misorientation angles in the range of 0.1-0.6 degrees. The characteristics and morphologies of sub-boundaries in Goss grains were analyzed based on the splitting directions and positions of Laue diffraction peaks. (C) 2016 Elsevier Ltd.
