Аннотация
An Fe–31Cr–20Co–3Mo (31Kh20K3M) alloy containing 0.09 wt % C, which is almost twice as much as its maximum content according to GOST 24897–81, has been studied to verify the influence of the carbon content on the magnetic hysteretic properties of hard magnetic high-chromium Fe–Cr–Co alloys. The optimal heat treatment, including thermomagnetic treatment, results in the average values of residual magnetic induction Br = 0.96 T and coercive force HcB = 63 kA/m and the maximum energy product (BH)max = 29 kJ/m3. Some heat treatment regimes give Br = 1.03 T, HcB = 72 kA/m, and (BH)max = 31 kJ/m3. In addition, for isotropic alloy samples, the following average values are obtained: Br = 0.71 T, HcB = 56 kA/m, and (BH)max = 15 kJ/m3. These magnetic hysteretic properties of the 31Kh20K3M alloy with an increased carbon content are similar to those of a powder 30Kh21K3M alloy with the minimum carbon content.
