An investigation of Fe74Si11B14Ni1 soft-magnetic powder

Fe74Si11B14Ni1 soft-magnetic material was prepared as a powder using water atomisation. Using this method, powder particles of less than 45 μm in diameter were obtained after sieving. In the as-water-atomised condition the powder particles were observed to be amorphous. Annealing resulted in the formation of a two-phase nanostructured morphology. The structure of the powders was investigated by high-resolution Auger electron spectroscopy (HRAES) and field-emission scanning electron microscopy (FE SEM) with WDS analytical technique.
