PRODUCTION METHOD OF HEAT-RESISTANT RARE-EARTH MAGNETS Russian patent published in 2013 - IPC H01F1/53 B22F3/12

Abstract RU 2493628 C1

FIELD: metallurgy.

SUBSTANCE: magnets may be used in automatics systems, industrial machinery and automobiles. Alloy is melted and its powder is obtained. Then powder is subjected to prepressing and sintering at temperature of 30-100 K below sintering temperature with further grinding of obtained workpiece together with 0.5-2.0 wt % of rare-earth metal hydride. Then pressing in magnetic field, sintering of pressings and thermal treatment are performed.

EFFECT: obtained magnets have high magnetic properties and provide increase of accuracy and stability of operation of navigation equipment and systems of aeronautic automatics.
