Popis:	The FeZrB amorphous alloys for simulating the intergranular amorphous phase in the nanocrystalline Zr7B4 soft magnetic materials were obtained by mechanical alloying of a mixture of elemental Fe, Zr and B powders for 25 h. It is shown that the Curie temperature of the simulated intergranular phase alloy is much lower than that of the intergranular phase with the same chemical composition in the nanocrystalline Fe89Zr7B4 alloy. The possible mechanism is mainly due to the strong ferromagnetic exchange force among the nanocrystalline α-Fe grains.
