Pr and Nd substituted ´2:17´ magnets for elevated temperature application

Results of Pr, Nd and (PrNd) substitution in the ´2:17´ type permanent magnet alloys are presented. Microstructural studies, crystal structure, anisotropy field (HA), Curie temperature (TC), and saturation magnetization (Ms) were used as tools for the evaluation of these alloys. Pr, Nd and (PrNd) increases Mswithout significantly affecting the Tc. HAdecreases when Sm is replaced by Pr, Nd or (PrNd). Several of the alloys investigated show promise to be permanent magnets.
