Microstructure And Magnetic Properties

The good DC magnetic properties can be achieved for 1J50 soft magnetic alloy by applying high temperature hydrogen annealing. Annealing process parameters, e.g., atmosphere, soaking temperature, and time, are critical to soft magnetic properties. Qualitative results had been done for years. However a quantitative research among process parameters, microstructure, and magnetic properties can be more comprehensive and specific. In this study, a serial of experiments for 1J50 samples under the Chinese national standards. The influence of annealing temperature and socking time on DC magnetic properties and microstructure of the samples has been investigated on DC magnetic properties and microstructure of samples. The result shows that annealing process parameters have a nonlinear effect on the development of material microstructure and magnetic properties. Furthermore, the models among magnetic property, grain size, and process parameters have been built to quantitatively describe the interrelationship in between.

AbstractThe relationship between microstructure and magnetic properties of a (Fe,Co)NbB-based nanocrystalline soft magnetic alloy was investigated by analytical transmission electron microscopy (TEM). The microstructures of (Fe0.5Co0.5)80Nb4B13Ge2Cu1 nanocrystalline alloys annealed at different temperatures were characterized by TEM and electron diffraction. The magnetic structures were analyzed by Lorentz microscopy and off-axis electron holography, including quantitative measurement of domain wall width, induction, and in situ magnetic domain imaging. The results indicate that the magnetic domain structure and particularly the dynamical magnetization behavior of the alloys strongly depend on the microstructure of the nanocrystalline alloys. Smaller grain size and random orientation of the fine particles decrease the magneto-crystalline anisotropy and suggests better soft magnetic properties which may be explained by the anisotropy model of Herzer.
