Ferrite Transformation in High Magnetic Field Monitored by in-situ Magnetic Measurements

For the first time, in-situ high temperature magnetic measurements are used to monitor the solid state transformations in steels. The magnetization provides information about the kinetic of the austenite to ferrite transformation, although care must be taken in the experimental procedure and in the data analysis. The isothermal transformation of ferrite following two regimes under magnetic field is confirmed together with the effect of the magnetic field on the nucleation of this phase.
