Abstract : The objective of the experiments reported here was to determine if alpha and beta-Zr could be distributed in the alloy by diffusion processes to influence the reaction kinetics within brief exposure periods at high temperatures in the range 870-1000C. It is demonstrated that this objective is feasible because, first, the solubilities of oxygen in the alloy phases differ by large factors, and second, the temperature coefficient for oxygen diffusion in alpha-Zr is of a relatively high value.
