【 摘 要 】

Amorphous Fe-Mo-Cu-B ribbons with varying Fe/B ratio were prepared by planar flow casting. Characteristic transformation temperatures as well as the transformation kinetics were determined by DTA and DSC analyses. The presence of magnetic phases was identified by VSM-magnetometry; the information about their local ordering was obtained using Mossbauer spectrometry. Structure analysis was performed by X-ray diffraction analysis and by transmission electron microscopy. In all cases, higher bcc-Fe crystallization temperatures and lower magnetization of crystalline samples are observed with increasing content of boron. (C) 2006 Elsevier B.V. All rights reserved.
