Abstract
Experiments were performed to determine the effect of structure on the mechanism of zirconium oxidation. It is shown that there is a high volume fraction of short circuit diffusion paths in the oxide formed on Zr in the temperature range 500–1000°C. The results of tracer experiments are in agreement with a short circuit diffusion mechanism. The assumption of line diffusion is shown to imply intuitively reasonable values of both the grain boundary thickness and the ratio of the line diffusion coefficient to the coefficient for lattice diffusion.
