研究了(Fe，Co)-B-Si-Nb非晶合金的非晶形成能力和磁性能。Fe72B20Si4Nb4形成玻璃合金棒的最大直径分别为2.0 mm和4.0 mm。对于(Fe0.5Co0.5)(72)B20Si4Nb4。用高分辨电子显微镜观察到Fe72B20Si4Nb4块状非晶合金中存在大量的局域有序区域。然而，在(Fe0.5Co0.5)(72)B20Si4Nb4块体非晶合金中没有观察到局部有序区域。(Fe0.6Co0.4)(72)B20Si4Nb4块体非晶合金的饱和磁化强度为1.14T，矫顽力为1.5A/m，最大磁导率为32000。(C)2005年美国物理研究所。
The glass-forming ability and magnetic properties of (Fe, Co)-B-Si-Nb glassy alloys have been investigated. The maximum diameter for the formation of a glassy alloy rod was 2.0 mm for Fe72B20Si4Nb4 and 4.0 mm. for (Fe0.5Co0.5)(72)B20Si4Nb4. A number of local-ordered regions are recognized in Fe72B20Si4Nb4 bulk glassy alloy by high-resolution transmission electron microscopy. However, no local-ordered regions are observed in (Fe0.5Co0.5)(72)B20Si4Nb4 bulk glassy alloy. Saturation magnetization, coercive force, and maximum permeability were 1.14 T, 1.5 A/m, and 32 000, respectively, for the (Fe0.6Co0.4)(72)B20Si4Nb4 bulk glassy alloy.
