Summary: | Method of producing a rare earth-transition metal-boron type alloy with a reduced free iron phase content, wherein the transition metal component of the alloy comprises iron, whereby at least one group IVB transition metal, such as zirconium, is added to the alloy mixture during the melting and casting of the alloy. The performance of the alloy produced by the method is further improved by the addition of additional boron to the alloy during the manufacture process. The present invention also provides for the magnetic alloys produced by the above method.
La présente invention concerne un procédé de production d'un alliage du type bore-métaux de transition-métaux des terres rares à teneur réduite en phase fer libre, tel que le constituant métal de transition de l'alliage comprend du fer, et au moins un métal de transition du groupe IVB, tel que le zirconium, est ajouté au mélange d'alliage pendant la fonte et le coulage de l'alliage. La qualité de l'alliage produit au moyen de ce procédé est encore améliorée par l'ajout de bore additionnel dans l'alliage pendant le procédé de fabrication. Cette invention se rapporte également aux alliages magnétiques produits au moyen du procédé selon l'invention. |
