Description
Disordered nature of structural arrangement in Fe-based metallic alloys gives rise to advantageous (from a practical application point of view) magnetic properties. Suitable heat treatment of metallic glasses produces the so-called nanocrystalline alloys. The latter attract a lot of scientific interest because, contrary to their amorphous counterparts, their magnetic parameters do not substantially deteriorate at elevated temperatures during the process of their practical exploitation. To benefit from their unique magnetic properties, the mechanism of stability comprising crystallization should be known. Here, we present the study of structural transformation of a Fe-Mo-Cu-B NANOPERM-type alloy by the help of Mössbauer spectrometry, conventional X-ray diffraction as well as by in situ (during continuous heat treatment) diffraction of synchrotron radiation. Additional information is provided by atomic field microscopy, transmission electron microscopy, and high resolution electron microscopy.
