NGR Investigation of Grain-Boundary Diffusion in Poly- and Nanocrystalline Nb

Abstract:

The properties of grain boundary cores and adjacent areas in polycrystalline Nb manufactured by rolling with subsequent recrystallization annealing and nanocrystalline Nb obtained by high pressure torsion have been investigated by the Mössbauer emission spectroscopy on 119mSn nuclei.
