Oxygen diffusion in beta zircaloy during steam oxidation
TL;DR: In this paper, analytical and finite-difference methods developed to deal with diffusion in finite systems with moving boundaries were used to compute oxygen concentration profiles in the beta phase of Zircaloy specimens oxidized in steam.

Oxide platelet formation in tantalum single crystals
TL;DR: In this paper, it was shown that the relative propensity for platelet formation parallel to a particular set of {320} planes varied inversely with the angle which that set made with the specimen surface.

The oxidation of zircaloy-4 at 900 and 1100°c in high pressure steam☆
TL;DR: In this article, the growth characteristics of the oxide and oxygen-stabilized alpha layers after these exposures were examined and compared to those observed earlier for oxidation in steam at atmospheric pressure.

Diffusion in a finite system with a moving boundary
TL;DR: In this paper, the approximate analytical solutions to the finite-geometry moving-boundary problem were presented and compared with those obtained by a finite-difference method based on a simple model of the system.
