Especially nanocrystalline alloys attract a lot of scienti?c 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 bene?t from their unique magnetic pr- erties, the mechanism of crystallization should be known. Here, we present the study of structural transformation of NANOPERM-type alloys by the help of Mössbauer spectrometry, conventional X-ray diffraction (XRD), and by an advanced diffraction of synchrotron radiation. 2 Experimental Alloys of the composition Fe Mo Cu B for x = 12, 15, 17, 20 prepared by 91?x 8 1 x 57 rapid quenching on a rotating wheel were analyzed in the as-cast state by Fe transmission Mössbauer spectrometry (TMS) and by conversion electron Mössbauer spectrometry (CEMS). The obtained as-quenched ribbons were about 10 mm wide and 20 ?m thick. The nanocrystalline state was achieved by annealing about 2 cm ? long samples for 1 h | | 出版日期 | Conference proceedings 2009 | | 关键词 | Exchange interaction; Hyperfine interactions; Mössbauer spectroscopy; heavy ion; spectroscopy | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-540-78697-9 | | isbn_ebook | 978-3-540-78697-9 | | copyright | Springer-Verlag Berlin Heidelberg 2009 |
