- Рассмотрен метод получения анизотропных магнитотвердых порошков Nd-Fe-B с помощью процесса гидрирования, диспропорционирования, десорбции и рекомбинации (Hydrogenation- Disproportionation-Desorption-Recombination, HDDR), застехиометрического по Nd относительно фазы сплава NdFeB. Изучены два различных подхода к технологии - динамический и твердофазный HDDR-процессы. Показана принципиальная зависимость магнитных гистерезисных свойств порошков от давления водорода и скорости его увеличения на стадии диспропорционирования. Установлено, что твердофазный HDDR позволяет получать порошки с лучшими магнитными гистерезисными свойствами по сравнению с динамическим HDDR.
