Abstract

The work is devoted to the study of the possibility of obtaining hard magnetic materials during the crystalli-zation of amorphous alloys of the Fe–Co–Cr–B–Si system. The influence of boron content in alloys on their glass-forming ability was analyzed. The structure and phase transformations in alloys during heating were ana-lyzed using X-ray diffraction and transmission electron microscopy. Influence of the phase composition on the magnetic properties of the alloys has been established. It is shown that the formation of a nanosized eutectic structure [α + (Fe, Cr)3B] during the crystallization of an amorphous matrix is promising for development of new hard magnetic materials.
