退火后的Fe 74 Cu 1 Nb 3SixB 22 − x合金的磁导率在Si浓度x = 14时出现最大值。磁导率最高的最佳退火温度与α-Fe晶格常数最小的退火温度有关。退火时α-Fe的晶格常数与Si的浓度有很强的依赖关系。在最佳退火温度下，α-Fe相的占据面积约为50%~ 80%，并取决于非晶合金中的B浓度。最佳退火温度下α-Fe的晶粒尺寸约为130 μ m，对磁导率无直接影响。
The magnetic permeability of annealed Fe74Cu1Nb3SixB22−xalloys shows a maximum value for an Si concentration ofx= 14. The optimum annealing temperature giving the highest magnetic permeability correlates with the annealing temperature showing the minimum value of the lattice parameter of α-Fe. The lattice parameter of α-Fe on annealing shows a strong dependence on the concentration of Si. The occupied area of the α-Fe phase at the optimum annealing temperature is about 50%–80%, and depends on the B concentration in the amorphous alloy. The grain size of α-Fe at the optimum annealing temperature is about 130 Å, which has no direct effect on the magnetic permeability.
