Sm2Fe17Nx Produced by Calciothermic Reduction Using Different Iron Powders

Article Preview

Abstract:

This paper compared the influence of the iron powder in the production of Sm2Fe17Nx by calciothermic reduction. Two available iron powders were used: Basf CL carbonyl iron and Ancor MH-100 sponge iron. Both alloys were prepared and analyzed with X-ray diffraction, scanning electronic microscope and vibrating sample magnetometer. The results showed that the alloy produced with Ancor Mh-100 presents a higher anisotropy. The alloy produced with Basf CL has a smaller anisotropy but a higher coercivity. This can be explained by the difference in the microstructure of the two powders.
