METHOD FOR PRODUCING POWDER MATERIALS FROM ALLOYS CONTAINING RARE-EARTH METALS, TRANSITION METALS, AND BORON; DEVICE FOR THE REALIZATION OF THE METHOD

摘要

The present invention relates to a method for producing powder materials from alloys containing rare-earth metals, transition metals, and boron that are used for producing permanent magnets. The proposed method implies using a planetary mill and is distinctive by that the raw material is placed into the hermetically sealed working chamber of the planetary mill. The chamber is filled with hydrogen or argon after previously evacuating air from the chamber. The proposed device for the realization of the method contains a planetary mill with a hermetically sealed chamber, a vacuum system for evacuating air from the chamber, equipment for filling the chamber with hydrogen or argon, and a manometer.
