英文摘要	Replacement of samarium (Sm) with abundant yttrium (Y) can help solve the potential shortage of Sm in the preparation of promising Sm2Fe17Nx magnets. In this article, phase composition, microstructure and magnetic properties of (Sm1-yYy)(2)Fe17Nx (y = 0, 0.2, 0.4, 0.6, 0.8, 1.0) were investigated. Maximum energy product (BH)(max) is improved when less than 40 at% Y is doped in (Sm1-yYy)(2)Fe17Nx powder. In particular, when 20 at% Y replaces Sm, (BH)(max) of (Sm1-yYy)(2)Fe17Nx powder increases by 15.1% from 131.7 to 151.6 kJ/m(3). The effect of annealing temperature on the structural properties of high Y doping (Sm0.6Y0.4)(2)Fe-17 and the magnetic properties of the corresponding nitrides were subsequently investigated. In the RE2Fe17 phase grain combination process, the interlaced structure of the rhombohedral Th2Zn17-type structural phase and the hexagonal Th2Ni17-type structural phase is formed. Due to short-range exchange coupling, the nitride with the highest content of two interlaced RE2Fe17 phases has the highest magnetic properties: B-r = 1.23 T, H-cJ = 443.9 kA/m and (BH)(max) = 197.6 kJ/m(3).
