The boundary microstructure of the sintered alloy Nd_(15.5)Fe_(77)B_(7.5) hasbeen studied by TEM, ASE and SAED. It may distinguish the boundaries into 4types. The first three types remain the same during annealing, and the 4th changesits microstructure remarkably. The 4th type of boundary microstructure is composedof two different regions, i. e., the central Nd-rich phase and the epitaxial layer ofthe Nd_2Fe_(14)B grains.

The boundary microstructure of the sintered alloy Nd_(15.5)Fe_(77)B_(7.5) hasbeen studied by TEM, ASE and SAED. It may distinguish the boundaries into 4types. The first three types remain the same during annealing, and the 4th changesits microstructure remarkably. The 4th type of boundary microstructure is composedof two different regions, i. e., the central Nd-rich phase and the epitaxial layer ofthe Nd_2Fe_(14)B grains. Owing to the atomic diffusion and other types of masstransport,magnetic hardening occurred in the epitaxial layers, thus the coercivity of the alloywill be improved.

用TEM观察了烧结NdFeB永磁合金的内边界显微结构,发现该合金存在4种类型的边界。回火前后前三类边界的形貌没有变化,而第4类边界的显微结构发生了显著的变化。用SAED和AES分析了第4类边界的成分与结构,该边界由两个区域组成,即富Nd相区和Nd_2Fe_(14)B晶粒的外延层。回火时,由于原子的扩散和物质迁移,Nd_2Fe_(14)B晶粒的外延层发生了磁硬化,因而合金的矫顽力得到提高。

Based on the observations of TEM, a microstructural model of Sintered NdFeB magnets has been found. The coercivity of the model was calcu-latedbased on micromagnetic theory and the coercivity of both Nd2Fe14B grains and sintered NdFeB magnets were analysed and discussed. A magnetic hardering theory of epitaxial layer of Nd2Fe14B grain and the way of increasing coercivity of sintered NdFeB magnets were put forward.

根据TEM观察,建立了三元烧结NdFeB系永磁体的显微结构模型。运用微磁学理论对矫顽力模型作了计算,并讨论了Nd_2Fe_(14)B晶粒和NdFeB系永磁体的矫顽力。提出了烧结NdFeB系永磁体Nd_2Fe_(14)B晶粒的外延壳磁硬化理论和提高其矫顽力的途径。

The oxidation of sintered NdFeB magnets in humid atmosphere at

用透射电镜、Auger能谱,X射线和Mossbauer等方法研究了烧结NdFeB永磁材料在90℃潮湿空气中的氧化行为。结果表明,黑色氧化组织先在富Nd晶界相处形成。沿晶界深入和扩展进入基体相Nd_2Fe_(14)B晶粒,形成表面氧化层。黑色组织内富O和Nd而贫Fe。经500h氧化后,粉末组成仍以Nd_2Fe_(14)B粒子为主,余为Fe_3O_4,Nd_2O_3和少量a-Fe_2O_3,立方Fe_2O_3。经氧化的Nd_2Fe_(14)B相四方晶格内Fe原子分布发生变化,c晶位Fe原子大部分逸失,这是氧化导致材料磁化强度降低的重要原因。
