Notes:
Pr14FebalCoxB6Nb0.1 magnets have been produced using the hidrogenationdisproportionation desorption recombination (HDDR) process. The effect of the Co content (x= 0,4, 8, 10, 12, 16) and the reaction temperature (800-900 ºC) on the microstructure and magneticproperties of the HDDR material have been investigated. The processing temperature(desorption/recombination) affected the microstructure and magnetic properties of the bondedmagnets. The alloy with low cobalt content (4 at.%) required the highest reaction temperature(880°C) to yield anisotropic bonded magnets. The optimum temperature for alloys with 8 at.% Coand 10 at.% Co were 840°C and 820°C, respectively. Alloys with high cobalt content (12 at.% and16 at.%) were processed at 840°C. Each alloy required an optimum reaction temperature andexhibited a particular microstructure according to the composition. Pr14Fe80B6Nb0.1 magnets havebeen processed for comparison
