The transformation temperatures and durations of solid state transformation in T8 steel before and after 4 GPa pressure treatment are measured using differential scanning calorimetry, and the transformation activation energy and Avrami exponent are also calculate. Then the effects of 4 GPa pressure treatment on solid state transformation kinetics in T8 Steel are investigated based on the kinetic parameters and the observation of microstructure. The results show that the solid state transformation in T8 steel shifts toward the low temperature region after 4 GPa pressure treatment. The high pressure treatment can reduce the phase transformation time and Avrami exponent and enhance the phase transformation activation energy, which is favorable for refining the grains but has little effect on the phase transformation mechanism.
