Influence of lattice defects on grain boundary self-diffusion in nickel

Original language description

An extremely wide spectrum of experimental results on the grain boundary (GB) self-diffusivities in nickel was published in the literature. Currently, our previously published results show a pronounced dependence of diffusivities on both purity and thermo-mechanical history. A possible reason for the large scatter of published experimental data could be a contribution arising from some crystal lattice defects other than GBs. Thus, in the present work, the impact of the selected lattice defects on diffusion processes, grain growth and twin production has been investigated. Hence, the cast and cold-rolled nickel specimens of purity grades from 99.5% to over 99.99% were selected to study the influence of the material purity and fabrication on microstructure and its evolution during thermal treatment and thereby on the mass transport properties.
