Magnetic hysteric properties and saturation magnetization of nanocrystalline iron

The paper presents the results of experimental studies of bulk nanocrystalline pure iron produced by two-steps severe plastic deformation. The processed samples are characterized by enhanced values of coercivity and saturation in comparison with a coarse grained state. Annealing leads to partial res...

Summary:The paper presents the results of experimental studies of bulk nanocrystalline pure iron produced by two-steps severe plastic deformation. The processed samples are characterized by enhanced values of coercivity and saturation in comparison with a coarse grained state. Annealing leads to partial restoration of the properties. High-temperature (1073 K) annealing results in complete restorations of properties due to recrystallization. Transmission electron microscopy and X-ray analysis were used for structural analysis.
