  • HRAES study of Sb, Sn and Se segregation on the FeSiAl alloy surfaces
    Jenko, Monika
    Surface and interface structure and composition of FeSi steels can affect their material properties during the production process and can have a pronounced effect on their use as electrical/magnetic ... steels. The primary aim of this study was to determine how selective segregation and surface texture development can affect the magnetic characteristics of non-oriented electrical steel sheets. We have investigated the mechanism and kinetics of segregation of silicon steels doped with surface active elements of Sb, Sn and Se using HRAES instrument. On such segregated surfaces we have experimentally confirmed the reconstruction of magnetically hard (110) grains into magnetically soft (100) ones. The reconstruction process was found to be consistent with the lower surface energy of the (100) orientation enhanced by the segregated elements. The surface texture of such surface reconstructed steels has resulted in an improvement of their electrical/magnetic properties which can be very important for steels used in electrical motors and transformers.
