摘要：

The magnetic properties and the crystallization process of rapidly quenched amorphous Nd14Fe81B5 alloys are studied by X‐rays diffraction and analysis of magnetic properties. The hard magnetic material with a maximum energy product (BH)max = 12.3 MGOe and a coercivity Hc > 13.6 kOe is obtained by annealing. A step is observed in the coercivity vs. field curve of the annealed sample. It may result from two magnetic phases in the sample. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
