Resumo
This paper reports the results of investigations carried out to determine the
magnetic properties of some praseodymium-based magnets represented by the formula
Pr14Fe63.9-xCo16B6Nb0.1Mx. Bonded magnets of various compositions were prepared from
annealed alloys using the hydrogenation, disproportionation, desorption and recombination
(HDDR) process. The HDDR powders were isostatically pressed and bonded with
cyanoacrylate adhesive to form permanent magnets. The effect of the addition element
content on the magnetic properties of these magnets was investigated. The amount of Al,
Cu and P addition has a significant effect on the magnetic behavior of these magnets. Under
the present processing condition 0.3 at%Al enhanced the intrinsic coercivity to 1.27 T and
0.1 at% P improved the remanence to 0.77 T. Copper addition was deleterious to the
magnetic properties of the HDDR bonded magnets, independently on the content added.
