采用传统的粉末冶金方法制备了名义成分为Sm 1-xLux（CobalFe0.125Cu0.08Zr0.06）7.4（x= 0，0.05，0.1，0.15）的2：17型SmCo永磁体。系统研究了稀土元素Lu含量对磁体显微结构和磁性能的影响。HRE Lu的加入已被证明导致显微结构和磁性能的相关改善，特别是在矫顽力Hcj。结果表明，当x = 0.15时，样品具有较高的矫顽力，最大能积分别为35.92kOe和28.52MGOe。同时，通过对选区电子衍射和高分辨透射电子显微镜图像的标定，对晶格常数进行了讨论。
The 2:17-type SmCo permanent magnet with nominal compositions of Sm1–xLux(CobalFe0.125Cu0.08Zr0.06)7.4(x= 0, 0.05, 0.1, 0.15) were prepared by a traditional powder metallurgy method. The influence of HRE Lu content on the microstructure and magnetic properties of these magnets were investigated systematically. HRE Lu addition has proved to result in relevant improvements in the microstructure and magnetic properties, especially in the coercivityHcj. It is shown that a higher coercivity and maximum energy product of about 35.92 kOe and 28.52 MGOe were obtained in the sample withx= 0.15. Meanwhile, the lattice constants have been discussed by indexing the selected area electron diffraction and HRTEM images.
