The effect of an external electric field on the crystallization behavior of amorphous(Nd0.1Fe0.9)3B alloy was investigated. The crystallization product of Nd2Fe23B3 phase was obtained for this amorphous alloy annealed at 923 K for 300 s in the presence of an external electric field of 300 kV·m-1(50 Hz); while the crystallization products are Nd1.1Fe4B4, α-Fe, and Fe3B phases under the same annealing condition except for free-electric field. On the other hand, the samples were annealed at 1023 K, which is higher than the decomposition temperature of metastable Nd2Fe23B3 phase, for 600 s. In the case of the presence of an external electric field, the metastable Nd2Fe23B3 phase, as a main phase, is still stayed in the sample. This fact suggests that the external electric field enhances the stabilization of the metastable Nd2Fe23B3 phase. The effect of the external electric field on the phase selection and stabilization was explained in terms of the specific conductance difference between the crystallization products.
