Abstract

La presente invención se refiere a un método para elaborar un imán permanente de hierro-metal de tierra rara, que comprende: prensar en caliente partículas magnéticamente isotrópicas de un material amorfo o finalmente cristalino, que tiiene un tamaño de grano menor de aproximadamente 500 manómetros y que comprende, sobre una base en porciento atómico, de 50 a 90 por ciento de metal de transición, del cual por lo menos 60 por ciento es hierro, de 10 a 50 por ciento de metal de tierra rara, del cual por lo menos 60 por ciento del total es neodimio y/o praseodimio, y al menos uno por ciento de boro, a una temperatura y presión elevadas durante un tiempo suficiente para consolodar el material en partículas en un cuerpo complatamente densificado; y enfriar el cuerpo; mediante el cual el cuerpo resultante prensado en caliente es magnéticamente anisotrópico y tiene una coercividad de 1000 oerstedios o mayor, a temperatura ambiente.
