Abstract
The influence of active elements on the extent and relaxation of different stresses generated in the scale and substrate of alumina-forming alloys during oxidation are discussed on the basis of observations of the scale and scalesubstrate interface morphology.
The intermetallic compound beta-NiAl has been selected as a model of an alumina-former. It is suggested that active elements reduce the growth stresses and change the way of stress-relief by favouring less detrimental mechanisms such as substrate and scale deformation. In the absence of these additions, scale cracking and spalling occur under less severe oxidation conditions. This change in behaviour is attributed to an enhancement of the adhesive forces between the scale and the substrate atoms and also of the cohesive forces between the oxide grains by active elements.
