On the Influence of Local Grain Scattering Fields in Annealed Low-Carbon Steels on Their Magnetization Reversal Processes

A number of new effects caused by local scattering fields from grains of annealed low-carbon steels with a change in magnetization along the back of the hysteresis loop are considered. It is established that only three magnetization components determine the nature of steel magnetization reversal in different intervals of the internal magnetic field. It is shown that these components in sum are always equal to the saturation magnetization. Taking into account the local scattering fields from steels grains leads to a difference in the internal magnetic fields in the grains of the above three magnetization components, which explains the influence of this effect on the features of their magnetization reversal. The experiments performed on samples of annealed 09G2 steel agree with the results of theoretical calculations.
