中文摘要 | The phase composition of melt-spun Nd-Fe-B with intermediate and high Nd concentrations has been studied by Mossbauer effect. Based on the knowledge of the Fe-57 hyperfine parameters for Nd2Fe14B, Nd2Fe23B3, and Nd1.1Fe4B4, the phases produced during annealing Nd-Fe-B amorphous alloys can be identified. It is found that the NdxFe81.5-xB18.5 samples with 7 less than or equal to L less than or equal to 9 contain the Nd2Fe23B3 metastable phase and the Nd1.1Fe4B4 paramagnetic phase. The body-centered-cubic structure of Nd2Fe23B3 cannot generate the hard magnetic properties. The samples with 12 less than or equal to x less than or equal to 15 consist of the Nd2Fe14B hard magnetic phase and the Nd1.1Fe4B4 paramagnetic phase, The large coercivity for the high Nd content Nd-Fe-B originates from the very fine size of Nd2Fe14B grains below the particle size of the single domain, which may contribute to a pinning effect of domain wall. |
