      abstract     = {The high chromium nickel base alloy 602 CA is used as
                      construction material for high temperature components in
                      aggressive environments such as gas burners or heat
                      exchangers. The high temperature oxidation behaviour of this
                      alloy is characterised by the formation of an external Cr2O3
                      scale and internal precipitation of alumina. The main goal
                      of the present investigation was to elucidate the effect of
                      aluminum on the subscale chromium depletion phenomena. The
                      chromium concentration profiles were found to be flat and
                      sometimes even increasing towards the oxide-alloy interface.
                      The experimental observations were interpreted in terms of
                      alloy thermodynamics, i.e. effect of oxidation induced
                      compositional changes on chemical potentials of the alloy
                      constituents. The concentration profiles in alloy 602 CA
                      observed during high temperature exposure were modelled
                      using the CALPHAD approach for thermodynamic and kinetic
                      calculations. Thermodynamic calculations revealed that the
                      Al depletion in the alloy subsurface due to internal alumina
                      precipitation leads to enhanced Cr diffusion towards the
                      alloy surface.},
