As a common feature,group IVb elements — Zr, Ti, Hf — exhibit a martensitic phase transition from the closed packed hcp structure (stable at low temperature) to the more open bcc structure. Diffusion properties in these metals are dominated by this phase transition. For instance the Zr self-diffusion increases by five orders of magnitude at the phase transition at about 840°C. A similar behaviour is known for most of the metal impurities in Zr of which the diffusivities are in the same order of magnitude as for Zr self-diffusion.
