Mössbauer Spectroscopy Studies of Grain Boundaries in Nanostructured Metals
The results of NGR studies of grain boundaries in nanocrystalline metals are briefly reviewed and analyzed together with the data of ordinary diffusion experiments. Grain boundaries in materials obtained both by powder technologies and severe plastic deformation (SPD) are considered. Possible factors causing accelerated mass transfer in every case are analyzed with the account taken of specific features of the structure of these materials.
