摘要

A new nanocrystalline alloy Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9 was cast initially as amorphous ribbons, and subsequent annealing above the crystallization temperature of the amorphous state created a homogeneous ultrafine grain structure of α-Fe(Si) solid solution with a typical grain diameter of 10 - 20 nm and a residual amorphous phase at the interface with a thickness of 4 - 5 atoms. In comparison with the amorphous alloys, this material has been found possessing high values of the saturation magnetic induction, low values of the coercivity and the high-frequency loss. It has become a novel soft magnetic material with excellent magnetic properties.
