The Effect of Heat Treatment on the Magnetic Properties of Nanocrystalline Fe-Ni-Si Powders

Abstract:

This paper investigates the effect of heat treatment on the magnetic properties of nanocrystalline Fe-Ni-Si powders prepared by mechanical alloying method which can be used in soft magnetic composites fabrication. Fe-85%, Si-10% and Ni-5% alloys were prepared using a vibrating disc mill. The magnetic properties of the samples were measured by a vibrating sample magnetometer (VSM) and the microstructural properties of the un annealed sample were measured by XRD and SEM. Three samples were annealed in three different temperatures from 500 °C to 600 °C and were compared with a sample without annealing. It was found that with increasing the annealing temperature, stress relieving and crystallite size increased whereas microstrain and saturation magnetization decreased.
