Concertation-Inhomogeneous Hard Magnetic Alloys of the Fe – Cr – Co System with Elevated Content of Cobalt and Boron

Resumo

The structure and magnetic properties of a powder alloy based on the Fe – Cr – Co system with elevated content of cobalt and boron are studied. The dependences of the magnetic induction and of the coercivity on the aging temperature are determined experimentally. It is shown that the introduction of boron into the alloy hinders precipitation of σ-phase and makes it possible to raise the cobalt content by 4% as compared to standard alloy 30Kh23K.
