Abstract
Results of formation of a ferromagnetic τ-phase and an antiferromagnetic ε-phase in alloys of type Mn54Al43C3 obtained by induction and arc melting and by rapid hardening of the melt are presented. The magnetic hysteresis properties of powders produced by high-power mechanical milling of the synthesized alloys are studied. The optimum temperature conditions for transformation of the ε-phase into a ferromagnetic τ-phase are determined for the alloys and for their ultrafine powders. The resulting powders of Mn54Al43C3 have an ultimate specific magnetization σm = 81 (G · cm3)/g and a coercive force Hc = 3 kOe in a magnetic field of 12 kOe.
