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 (H
A
), Curie temperature (T
C
), and saturation magnetization (M
s
) were used as tools for the evaluation of these alloys. Pr, Nd and (PrNd) increases M
s
without significantly affecting the T
c
. H
A
decreases when Sm is replaced by Pr, Nd or (PrNd). Several of the alloys investigated show promise to be permanent magnets.
