The growth of bainitic ferrite is a couple process of the shear transformation of Fe atoms with the diffusion of C atoms.The diffusion growth of the ferrite is impossible when the tempera- ture is below 400℃,and the paraequilibrium shear growth may occur at the temperature be- low 550℃.This paraequilibrium shear growth model explains the overlap of the bainites created from two growth mechanisms at 400—550℃.
