Resumo
An evaluation of the effect of alloying elements on the microstructure and
magnetic properties of Pr15FebalCo8B7Nb0.05Mx (M = Al, Cu, P, Si, Gd, Ga, Dy or Tb; 0 ≤
x ≤ 0.5) sintered magnets has been carried out. A mixture of alloys and the high-energy
milling technique have been used to prepare the magnets. The alloying elements have
influenced the remanence, intrinsic coercivity and the squareness factor (SF). In
general, Br has been reduced somewhat for the magnets with alloying additions. On the
other hand, µ0iHc and SF exhibited some improvements compared to the standard
composition Pr15FebalCo8B7Nb0.05 magnet, particularly SF. The concentration of the
alloying elements showed no influence on the density of the magnets, which ranged
between 97% and 99% of the theoretical value. Comparisons between the squareness
factors obtained using the J×µ0H curve profile and the estimated using microstructural
parameters have also been carried out.
