Fe–Cr precursors for hardmagnetic material of Fe–Cr–Co system

L. B. Vedmid, G. А. Dorogina

ABSTRACT:

The article deal with influence of the chromium concentration on magnetic properties of Fe–Cr precursors for hard magnetic material of Fe–Cr–Co system. The result of investigation is increasing of coercive force of alloy if we use nitrogen as material sintering atmosphere and increase annealing duration. The evolution of phase formation in Fe–30% Cr alloys in heat treatment with nitrogen and argon atmosphere was defined using thermal analysis.
