| Abstract: | The cold rolled (reduction of 75%) IF steel sheet of 1mm thickness was heat-treated at different annealing temperatures, respectively. By means of optical microscopy, X-ray diffraction and EBSD analysis, the microstructure and main texture evolution and grain boundary misorientation distribution characters in IF steel sheet under different annealing parameters were investigated. The results showed that the amount of low-angle grain boundaries decreased with the increase of the annealing temperature. When the annealing temperature above 800C, the grain size and the strength of g texture component increase rapidly. |
