Sm2Fe17Nx Produced by Calciothermic Reduction Using Different Iron Powders

Article Preview

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.
