Abstract
The effect of an external electric field on the crystallization behavior of amorphous B-rich NdFeB alloy of Nd4Fe78B18 has been investigated. The crystallization product of Nd2Fe23B3 phase is obtained for this amorphous alloy annealed at 923 K for 5 min in the presence of an external electric field of 3 kV/cm (50 Hz), while the crystallization products are Fe3B, Nd2Fe14B and α-Fe phases under the same annealing condition except for free-electric field. On the other hand, an external electric field enhances the stabilization of the metastable Nd2Fe23B3 phase. The effect of an external electric field on the phase selection and stabilization is explained in terms of the specific conductance difference between the crystallization products.
