Abstract

Magnetic metallic glasses (MGs) have been widely used, however, their trade-off between glass-forming ability (GFA) and magnetic properties is hard to be broken for novel alloys development. Here, combined CALPHAD and experimental approaches are proposed and used to efficiently design high Bs FeNiBSiNb bulk MGs. The phase diagrams obtained by using CALPHAD method can help us to select glass-forming elements and determine the optimal composition ranges. Accordingly, the (Fe0.5Ni0.5)x(B16.5Si5Nb2.5)(100- x )/24 alloys with x = 74–80 exhibit high GFA are successfully developed and then cast into bulk samples. After optimal annealing, these alloys exhibit excellent magnetic properties, including high Bs of 0.70–0.93 T, ultra-low Hc of 0.5–2.0 A/m and a moderate µe with low sensitivity to the composition, applied field and frequency. These results provide technical and theoretical guidance for developing high performance soft magnetic MGs to be used in a variety of electronic devices.
