MANUFACTURING METHOD OF MAGNETS FROM RARE-EARTH METALS Russian patent published in 2015 - IPC H01F41/02 B22F1/00 C22C28/00 C22C33/02 C22C38/00 H01F1/53 H01F1/08 

Abstract RU 2538272 C2

FIELD: metallurgy.

SUBSTANCE: manufacturing method of rare-earth magnets involves a stage of bringing a compacted item obtained by hot processing in order to create anisotropy in a sintered item having a rare-earth magnetic composition in contact with alloy melt with a low fusion temperature, which contains a rare-earth element.

EFFECT: increasing a coercitive force without any addition of large amount of such rare-earth elements as Dy and Tb.
