In order to find an effective means of production of the interstitial Sm2Fe17Nx-type nitride, an alloy modification by the addition of small amount of alloying element (4 at.% Nb) and a hydrogenation treatment prior to the nitriding process have been employed. The effect of previous hydrogenation on the nitride formation of the Sm2Fe17(4 at. % Nb) alloy has been investigated systematically by means of thermopiezic analysis, thermomagnetic analysis, and vibrating sample magnetometer. It has been found that the previous hydrogen treatment facilitates significantly the formation of the nitride, and this may be due to the clean surface and the finer size of the particles caused by the hydrogen decrepitation. It has also been found that the combination of the alloy modification with the addition of Nb and the previous hydrogen treatment can be utilized effectively for the production of a Sm2Fe17Nx-type nitride.
