Abstract：With the rapid development of Nd-Fe-B magnets， it is of great significance to make rational use of relatively cheap rare earth elements such as La， Ce， Y to reduce production costs. Studying the influence of Y substitution on the magnetic properties of Nd-Y-Fe-B magnets is helpful to the development of other novel magnets. The effects of Y substitution for Nd or Fe on the magnetic properties of rare earth permanent magnet materials were summarized， including the intrinsic magnetic properties of Nd-Y-Fe-B alloy， the magnetic properties of Nd-Y-Fe-B sintered magnet， and the magnetic properties and microstructure of Nd-Y-Fe-B nanocrystalline magnet.
