## Description

- description: Oxide growth and O dissolution during the oxidation of an α-Ti alloy
    at 973 K were simulated using the finite volume method coupled with the CALPHAD
    method. The addition of 11.02% Al to a Ti–O system caused the formation of Al2O3
    with a thickness of 18 nm, which suppressed the TiO2 growth and O dissolution
    in the substrate. An increase in the O concentration at the oxide/metal interface
    was inhibited by Al2O3 formation. A thin Al-depletion zone was formed at the oxide/metal
    interface. Al2O3 formation was restricted by the low content and slow diffusivity
    of Al in the substrate.
