摘 要：The magnetic properties and microstructure in a low cobalt Fe-25.5Cr-12Co alloy by different process of thermomagnetic treatment were investigated. It is found that magnetic properties are sensitive to parameters of thermomagnetic treatment process in magnetic field, including temperature, time and applied magnetic field. There are optimized isothermal aging temperature and time in different magnetic heat treatment conditions. High magnetic field strength could improve magnetic properties. Applied magnetic field has a great effect on microstructure of the Fe-25.5Cr-12Co alloy. The finer ferromagnetic α1 particles with suitable c/a ratio by high magnetic field magnetic heat treatment are attributed to improvement the magnetic properties.
