The effect of particle size distribution on the magnetic properties of Pr-Fe-B sintered magnets. 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/123456789/15565.http://repositorio.ipen.br/handle/123456789/15565This paper reports the results of investigations carried out to determine the influence of the particle size distribution on the magnetic properties of Pr16Fe76B8sintered magnets. Permanent magnets were prepared from the cast alloy using the powder metallurgy route and the hydrogen decrepitation process. The effect of the balls shape and weight on the particle size distribution was investigated. Spherical milling balls yielded magnetic powder with a single particle size distribution whereas spherical/tori balls yielded hydride powder with a bimodal particle size distribution.openAccessparticle sizemagnetic propertiesmillingpraseodymium base alloyshydridesThe effect of particle size distribution on the magnetic properties of Pr-Fe-B sintered magnetsTexto completo de evento
