• chain-like ferrite
• proeutectoid ferrite
• Pillbox model
• high magnetic field

Pillbox model and Zener equation were used to analyze the nucleation and growth of proeutectoid ferrite with chain-like structure under high magnetic field. The factor of nucleation shape was discussed. Calculation results showed that due to the demagnetization, nucleation was much easier on the grain boundary parallel to the magnetic field than that perpendicular to it. Considering the interaction between magnetized ferrite nuclei, the formation of chain-like ferrite was explained dynamically.
