Abstract A theoretical analysis has been made on the effect of deformation above Ae3 temperature to the nucleation of proeutectioid ferrite transformation in low carbon steel. There are two types of influence differentiated by strain, here mainly focuses on one that ε<0.36. The influence of deformation parameters to deformation energy is discussed. The calculation results show that transformation starting temperature and maximum nucleation temperature raises when adding deformation, nucleation rate increases at the same temperature, incubation time becomes shorter, and with increased nucleation rate, finer ferrite can be obtained if grain growth is controlled.
