摘要

According to the local equilibrium model, the ferrite growth in Fe-C-X-i system could be divided into the partition local equilibrium (PLE) model and no partition local equilibrium model (NPLE). A method was developed to calculate the PLE/NPLE transition temperature in FeC-X-i system according to the thermodynamic models. Using this method, the PLE/NPLE transition temperature in Fe-C-X-i system were calculated.
