Description

A model for anomalous diffusion in the bcc phase of group-IVB 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 ω phase. An expression for the diffusion coefficient is derived from a phenomenological free energy of formation of an ω embryo. Excellent agreement is obtained with experimental data for bcc Zr. (auth)
