Abstract

This article reports the results of investigations carried out to determine the microstructure and magnetic properties of some permanent magnets represented by the formula Pr₁₄Fe₇₉.₉₋ₓCoₓB₆Nb₀.₁ (x=0, 4 and 8). Magnets were prepared from annealed alloys using the hydrogenation, disproportionation, desorption and recombination (HDDR) process. The effect of the disproportionation temperature on the magnetic properties and microstructures of these magnets was investigated. This processing temperature has a significant effect on the magnetic behaviour of these alloys.
