In this work, the effects of the thermal heating on an as-cast Fe-based amorphous ribbon treated in a conventional furnace are reported. We used thermogravimetry, differential scanning calorimetry, X-ray diffraction and MvsH measurements to characterize the samples. The transition temperatures of ma...

Description
Summary:In this work, the effects of the thermal heating on an as-cast Fe-based amorphous ribbon treated in a conventional furnace are reported. We used thermogravimetry, differential scanning calorimetry, X-ray diffraction and MvsH measurements to characterize the samples. The transition temperatures of magnetic phases (amorphous residual matrix and Fe 3 Si nanoparticles), which were estimated from thermogravimetric measurements, are thermal heat dependent. Besides, the analysis of the DSC data allows us to evaluate the crystallized fraction. From Rietveld refinement of the XRD diffraction patterns carried out after the DSC measurement, we confirm that the crystallized grains consist of Fe 3 Si (suessite) nanocrystalline phase. The suessite phases should be embedded inside the residual amorphous matrix. Furthermore, we synthesized a Fe 3 Si bulk sample using an arc furnace in order to compare its magnetic behavior with those Fe 3 Si nanoparticles. Finally, the magnetic anisotropy also shows to be thermal heat dependent.
