Abstract: Microstructures deformation induced ferrite under the conditions of various strains at 780°C with 1 s-1 strain rate were investigated by means of optical microscopy and transmission electron microscopy. The influence of strains on the amount and size of deformation induced ferrite was discussed. Results show that morphology of deformation induced ferrite is similar to that of normal annealing ferrite, and the size of deformation induced ferrite is obviously decreased. The increase in amount of the deformation induced ferrite is due to deformation enhancement in phase transformation. The decrease in size of deformation induced ferrite is due to the enhancement of recrystallization.
