Abstract
The composition design for the Fe-based amorphous alloys with high Fe contents is introduced based on the Nearly-Free-Electron model, which indicates that there is a favorable electron concentration (e/a) value for amorphous formation. The FeBPSn amorphous alloys with Fe contents higher than 83% have been prepared based on the favorable (e/a) value. The influences of Sn on the amorphous forming ability (AFA) and magnetic properties are investigated using X-ray diffraction (XRD), differential scanning calorimetry (DSC), and vibrating sample magnetometer (VSM), respectively. The results show that the inflexion of the coercive force Hc ~ (e/a) relationship is just contrary to that of the AFA ~ (e/a) relationship. The present work provides a convenient way to design Fe-based amorphous alloys with good magnetic performances by the metalloid admixture according to the favorable (e/a) value.
