The Nd self-diffusivity has been studied in nanocrystalline Nd-rich Nd2Fe14B. From the analysis of the diffusion profiles grain-boundary diffusion coefficients DGBNd are derived similar to the values observed recently for 59Fe diffusion in this material. Above the intergranular melting transition, a second diffusion path indicates rapid diffusion in the liquid intergranular phase. [ABSTRACT FROM AUTHOR] |
