摘要：

Polymer-bonded magnets have been made from powdered material of the alloys Nd16Fe76B8 and Nd12.3Fe81.9B5.8 (Nd2.1Fe14B) by a hydrogenation-disproportionation-desorption (HDD) process. The HDD process resulted in the production of fine-grained homogeneous materials (from the coarse-grained, non-homogeneous cast alloy) which exhibited appreciable coercivities and remanences characteristic of isotropic materials. Optimum annealing conditions were established for both alloys and superior coercivities were observed for the alloy richer in neodymium. © 1990.
