Magnetic susceptibility disaccommodation and Mössbauer studies of high silicon–iron alloy obtained by different methods

The microstructure and soft magnetic properties, i.e. the initial susceptibility and its disaccommodation for the Fe–6.5 wt% Si samples in the form of ribbons (obtained by rapid quenching) and sheets (prepared by a chemical vapour deposition method) were studied. The investigations were performed fo...

Description
Summary:The microstructure and soft magnetic properties, i.e. the initial susceptibility and its disaccommodation for the Fe–6.5 wt% Si samples in the form of ribbons (obtained by rapid quenching) and sheets (prepared by a chemical vapour deposition method) were studied. The investigations were performed for the samples annealed at 1373 K for 1 h and then cooled to room temperature in a furnace or in icy water. It was reported that in the samples cooled in a furnace, B2 superstructure in 50% sample volume is observed. However, the higher rate of cooling leads to the short-range ordering of silicon atoms. Simultaneously, better soft magnetic properties, i.e. the lower stabilization field and disaccommodation intensity, and higher initial permeability for the samples cooled in water were observed.
