Abstract

The crystallization process of amorphous Fe80B20−xSix (x=0, 2, and 8) ferromagnetic alloys has been studied by using 57Fe Mössbauer spectroscopy and X-ray diffraction studies. Results for samples heat treated at different temperatures for different times show that the crystallization of Fe80B20−xSi x samples having x=0 and 2 leads to α-Fe and t-Fe3B, while for x=8, it leads to α-Fe, t-Fe2B, and perhaps Fe-Si. It is further observed that the addition of silicon to the Fe-B system improves the thermal stability of the system.
