- Аннотация: Permanent magnets of Nd-Tb(Dy)-Fe-B system were studied for their remanent induction and coercive force depending on the quenching temperature within the range of 300-600°C. Extremal temperature dependence of coercive force is revealed with the maximum of 25-30%. For specimens of (Nd0.9Dy0.1)16Fe76B8 composition the coercive force increases from 13.2 up to 16.8 kA/cm, and for (Nd0.9Tb0.1)16Fe76B8 magnets - from 16.8 up to 20.0 kA/cm. Remanent induction remains practically unchanged.
