METHOD OF PREPARING POWDER MATERIAL OF FE-CR-CO SYSTEM FOR PERMANENT MAGNETS Russian patent published in 1995 - IPC

Abstract RU 2038918 C1

FIELD: metallurgy. SUBSTANCE: method comprises steps of preparing a charge by mixing powders of ferrum, chrome, cobalt and ferroalloys of titanium, silicium and (or) vanadium in such a way, that a total content of ferroalloys in the charge consists (0.7-2) mass pressing the charge, sintering it, subjecting sintered blanks to heat treatment and then subjecting them to thermomagnetic treatment. EFFECT: enhanced quality of magnets of such material. 1 cl, 1 tbl
