研究了B_2O_3熔剂熔炼对铸态96Nb_4大块非晶合金软磁性能的影响Fe0.75B0.20Si0.05通过B2O3熔剂熔化和铜模铸造制备的环形块状试样（熔剂试样）显示出平坦的磁滞曲线，表明磁感应强度与施加的磁场之间具有良好的线性关系。虽然焊剂试样的磁导率比常规铜型铸造试样的磁导率低一个数量级，但它们的磁导率几乎相同。这些结果表明，有可能开发出一种新的软磁材料，表现出恒定的磁导率，低铁损。
The effect of B2O3 flux melting on the soft magnetic properties of (Fe0.75B0.20Si0.05)96Nb4 bulk metallic glass prepared by casting has been investigated. Ring-shaped bulk specimens that were prepared by B2O3 flux melting and Cu-mold casting (fluxed specimens) show a flat hysteresis curve, indicating a good linear relationship between the magnetic induction and the applied magnetic field. Although the permeability of the fluxed specimens is lower than that of the specimens prepared by conventional Cu-mold casting by one order of magnitude, their coercivities are almost same. These results show that it is possible to develop a new soft magnetic material that exhibits constant permeability with low core loss.
