Abstract

The diffusion mechanism of nitrogen atoms in ThMn12-type crystal structure compounds was investigated by using x-ray diffraction, Mössbauer spectroscopy measurements, thermopiezic analysis, and differential thermal analysis. The studies indicate that the distribution of nitrogen atoms in a R(Fe,M)12 particles with intermediate N content is characterized by a nitrided region and an unnitrided region. The results confirmed that this two-phase region is stable, and the nitrogen atoms do not diffuse further into the particle. Based on the characteristics of the nitrogenation, a trapping diffusion model is applied to the R(Fe,M)12 system. On the basis of this study high performance magnetic powders of NdFe10.5Mo1.5NX were successfully prepared.
