Phase-field simulations were performed to elucidate the effect of internal stress field on the pearlite transformation in eutectoid steel. We constructed a phase-field model by assuming the Isaichev orientation relationship between ferrite (α) and cementite (θ) phases. The α and θ phases cooperatively grew and a large amount of elastic energy occurred in the pearlite region. In particular, the elastic energy in θ phase was found to be extremely high. From the simulations with/without considering the elastic energy, it was revealed that the transformation velocity decreased due to the presence of the internal stress field.
