HEAT TREATMENT METHOD OF HARD-MAGNETIC ALLOYS BASED ON IRON-CHROME-COBALT SYSTEM Russian patent published in 2014 - IPC C21D1/04 C21D6/00 C21D8/12

Abstract RU 2511136 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, and namely to production of hard-magnetic alloys based on Fe-Cr-Co system, which are used in instrument-making industry, relay engineering, electric machine engineering, medicine and automobile industry. In order to increase residual induction, alloy is subject to homogenisation, hardening, thermomagnetic treatment and multistage annealing; with that, heating of alloy to thermomagnetic treatment temperature is performed in a magnetic field.

EFFECT: improved efficiency of the method.
