Description
Summary:A condition of oxide-scale spalling is derived from the concept of strain energy proposed by Evans. By considering the probabilistic distribution of fracture strain energy across the metal oxide interface, the fraction of oxide scale spalled is described as a function of the weight of oxide before cooling and temperature change. The cyclic-oxidation behavior is modeled with this result. The prediction by the model is shown to be in good agreement with data on the oxidation behavior under thermal cycling.
