Concomitant oxidation-diffusion-creep processes for stress generation and suppression of oxide-alloy interfacial instabilities

Metallic materials under extreme thermo-mechanical-environmental service conditions oftentimes rely on the formation of dense and protective oxide layers, e.g., typically alumina or chromia. Their failures, however, usually emerge from the morphological instability of such layers at the oxide-alloy interface. This work suggests that a tensile, biaxial stress arises in the substrate alloy due to the concomitant oxidation-diffusion-creep...
