通过改变[(Fe0.5Co0.5)0.75B0.20Si0.05]100−xNbx（x= 3.6-4.4）合金体系中Nb的含量来优化合金成分。结果发现，铌的含量为4.3 at。%对于接近合金的共晶点是有效的。通过铜模铸造，成功地合成了[(Fe0.5Co0.5)0.75B0.20Si0.05]95.7Nb4.3直径达4 mm的块状非晶合金棒材。这些合金具有较高的饱和磁化强度（0.77 T）和较低的矫顽力（2.5 a /m）。
We optimized the alloy compositions by modifying the Nb content in [(Fe0.5Co0.5)0.75B0.20Si0.05]100−xNbx(x=3.6–4.4) alloy system. As a result, it was found that the Nb content of 4.3 at. % was effective for approaching alloy to a eutectic point. By copper mold casting, [(Fe0.5Co0.5)0.75B0.20Si0.05]95.7Nb4.3 bulk glassy alloy rods with diameters up to 4 mm were successfully synthesized even using commercial raw materials. These glassy alloys exhibit a rather high saturation magnetization of 0.77 T and low coercive force of 2.5 A/m.
