摘要： A Fe-based amorphous alloy containing subnanometer-scale ordered clusters, and a preparation method and a nanocrystalline alloy derivative thereof. The composition expression of the Fe-based amorphous alloy is FeaSibBc(CudXe)MfM′g, and X is at least one of Ti, Zr and Hf, M is at least one of V, Ta and Nb, and M′ at least one of Co, Ni, C, P, Ge, Cr, Mn, W, Zn, Sn, Sb and Mo; a, b, c, d, e, f and g respectively represent the atomic percent (percentage of the number of atoms) of the corresponding element, and satisfy: 74≤a≤82, 8≤b≤15, 4≤c≤10, 0.5≤d≤1.2, 0.4≤e≤1.8, 1≤f≤3.5, 0≤g≤1, 0.8≤e/d≤1.5 and a+b+c+d+e+f+g=100; the Fe-based amorphous alloy is a composite material composed of an amorphous alloy matrix with atoms arranged in complete disorder and ordered atomic clusters having the size ranging from 0.5 nm to 2 nm uniformly dispersed and distributed in the matrix. The Fe-based amorphous alloy has ultrahigh permeability: the permeability at the frequency of 100 kHz is more than 35000, and the saturation flux density more than 1.3 T.
