Title (EN) METHOD PRODUCING RARE EARTH MAGNET
(FR) PROCÉDÉ PERMETTANT DE PRODUIRE UN AIMANT AUX TERRES RARES
Abstract: front page image
(EN)A method of producing an R-T-B rare earth magnet that include forming an R-T-B (R: rare-earth element, T: Fe, or Fe and partially Co that substitutes for part of Fe) rare earth alloy powder into a compact and performing hot plastic working on the compact, characterized in that the hot plastic working is performed in a direction that is different from the direction in which the forming was performed.
(FR)La présente invention a trait à un procédé permettant de produire un aimant aux terres rares R-T-B, lequel procédé inclut les étapes consistant à former une poudre d'alliage des terres rares R-T-B (R : élément des terres rares, T : Fe, ou Fe et partiellement Co qui se substitue à une partie de Fe) en poudrier et à effectuer un travail de plastique à chaud sur le poudrier. Le procédé est caractérisé en ce que le travail de plastique à chaud est effectué dans une direction qui est différente de la direction dans laquelle la formation a été effectuée.
