Oxygen Diffusion in Zircaloy-4

Corvalan-Moya et al. [2010Cor] measured the oxygen diffusion profiles in low-Sn Zircaloy-4 at different temperatures. Diffusion Module (DICTRA) simulations were made to compare with the measured data.

The plot shows the calculation and comparison result of oxygen diffusion in BCC Zircaloy-4 at 1523 K for 309 s.
