The thermophysical properties of oxide scale, in the general case, are affected by the variation of the temperature of phase transitions (either magnetic or polymorphic) in its components due to impurities, lattice defects, grain sizes, etc. In this case, since the phase transition is usually accompanied by a sharp change in properties, even a small shift of such a critical temperature can lead to large changes in properties in its vicinity. In order to account for this effect, data known from…
