The effect of a high magnetic field up to 30T on phase transformation temperature and microstructure of Fe-based alloys has been reviewed. A high magnetic field accelerates ferrite transformation, changes the morphology of the transformed microstructures and increases the A3 and A1 temperature. In a magnetic field of 30T, the A1 temperature increases by about 37.1 ℃ for Fe-0. 8C, the A3temperature for pure Fe increases by about 33. 1 ℃. The measured transformation temperature data are not consistent with calculation results using Weiss molecular field theory. Ferrite grains are elongated and aligned along the direction of magnetic field in Fe-0.4C and Fe-0. 6C alloys by ferrite transformation, but elongated and aligned structure was not found in pure Fe, Fe-0. 05C alloy and Fe-1.5Mn0.11C-0. 1V alloy.
