| 摘 要： | 通过对Ｎｄ－Ｆｅ－Ｂ－Ｏ四相平衡的分析，定量计算了在一定工艺条件下Ｎｄ－Ｆｅ－Ｂ烧结磁体中的主相、富Ｎｄ相、富Ｂ相和氧化物相的体积分数以及磁体的室温剩磁和磁能积。Ｂｒ和（ＢＨ）ｍａｘ分别为１．５２８Ｔ和４５１ＫＪ／ｍ＾３是有可能制作出的烧结Ｎｄ－Ｆｅ－Ｂ磁体的磁性能极限。

| Abstract: | The volume fraction of Nd 2Fe 14 B,Nd 90 Fe 4B 4, Nd 1.1 Fe 4B 4 and Nd 2O 3 phases in sintered Nd Fe B magnets is calculated on base of the four phases equilibrium analysis of Nd Fe B ,and the magnetic properties are also evaluated. The remanence and magnetic product of about 1.523T and 451kJ/m 3, respectively, is the utmost magnetic property of Nd Fe B sintered magnet that can be practically fabricated. |
