摘要：

The influence of samarium concentration and nitriding kinetics on the structure of mechanically alloyed SmxFe100-x nitride was studied. The study of the nitriding kinetics confirmed that the nitrogen concentration in these materials cannot be varied continuously. Chemical analysis showed that a stoichiometric nitride Sm2Fe17Nx with x=2.66 was formed after nitriding. A maximum coercive force of 36.1 kOe was measured in SM14Fe86 nitride. An energy product of 12.8 MGOe with a coercive force of 29.5 kOe was obtained for Sm13Fe87 nitride. This work shows that further significant improvement in energy product can be achieved only by the development of anisotropic samples.
