Effect of heat treatment modes on the structure and magnetic properties of sintered permanent magnets based on Sm(Co, Fe, Cu, Zr) Z

  • Published:
Metal Science and Heat Treatment Aims and scope

Methods of x-ray diffraction analysis and light and scanning electron microscopy are used to study the effects of the cooling rate in quenching from the temperature of homogenization on the phase composition and structure of alloy Sm(Co0.65Fe0.26Cu0.07Zr0.02)7.5 in the states right after quenching and after a complete heat treatment and on the formation of structure in isothermal tempering. The magnetic properties of the alloy are shown to depend on the rate of the quenching cooling and on the time of the isothermal tempering. An optimum mode of heat treatment for alloys of the studied composition is developed.
