FIELD: technological processes.
SUBSTANCE: invention relates to production of powder of magnetically hard alloys. Method of producing powder of magnetically hard alloy 30H20K2M2V of iron-chrome-cobalt system involves preparing a mixture of powders of iron, chromium, cobalt, molybdenum and tungsten, moulding produced mixture, sintering, thermal treatment and thermo-magnetic treatment. After sintering before thermal treatment, method comprises hot plastic deformation with drawing of not less than 1.1. Thermo-magnetic treatment is carried out in temperature range 650–600°C.
EFFECT: sintering temperature of alloy is lowered and magnetic hysteresis properties of alloy are improved while maintaining high coercitive force.
