The influence of Pr concentration on the magnetic properties of Pr-Fe-Co-B-Nb. In: INTERNATIONAL LATIN-AMERICAN CONFERENCE ON POWDER TECHNOLOGY, 4th, Nov. 19-21, 2003, Guaruja, SP. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/15566.http://repositorio.ipen.br/handle/123456789/15566Permanent magnets were produced from homogenized alloys using the hydrogenation, disproportionation, desorption and recombination (HDDR) process. The influence of Pr concentration on the magnetic properties of these magnets was studied. Under the present processing conditions Pr has a significant influence on the magnetic behaviour of these magnetic alloys. Microstructural examinations revealed that free iron was completed eliminated from all studied alloys with annealing.openAccesspraseodymium base alloysmagnetic materialsmagnetic propertiesmicrostructureannealingscanning electron microscopyTexto completo de evento
