Notes:
Abstract NiO scales were formed on pure Ni and Ni-0.1 wt.% Y alloy by oxidation in pure O2 at 1200°C, and the grain boundary self-diffusion coefficients of Ni in the dense region of the scale were measured by the tracer-sectioning technique. The volume diffusion coefficient was also measured in the alloy scale. The grain boundary and volume diffusion coefficients and the grain boundary width were found to be the same for the two materials within the experimental uncertainty.
