Abstract
A model for anomalous diffusion in the bcc phase of group- transition metals is proposed, based on the identity of structure of the activated complex for diffusion and the basal plane of the low-temperature metastable phase. An expression for the diffusion coefficient is derived from a phenomenological free energy of formation of an embryo. Excellent agreement is obtained with experimental data for bcc Zr.
