The devitrification of the Fe65 N10B25 and Fe70 Nb10B20 metallic glasses produced by melt spinning has been studied by calorimetry (DSC), X-ray diffraction (XRD) and transmission Mössbauer spectroscopy (TMS). Calorimetric measurements show three exothermic peaks which have been identified as the successive primary nanocrystallization of mainly a Fe23B6-type phase, the formation of bcc-Fe and metastable borides and finally the transformation to the stable phases. TMS and XRD have been used to identify and follow the evolution of the phases that appear in the different transformations. © 2008 Advanced Study Center Co. Ltd.
