Abstract
The distribution of stable zinc isotopes in the regions of bulk and grain-boundary diffusion of zinc in bicrystals of Fe+5 at.% Si with tilt grain boundary [100] 43° is studied by means of local secondary ion mass-spectrometry. Two-dimensional images are obtained which evidently show the existence of regions of wetting rapid diffusion (premelting region) and common diffusion on the grain boundary. The isotope effect is determined for bulk diffusion and diffusion along premelting layer for zinc isotope pairs 64/66, 64/67 and 66/67.
