Interactions of corrosion and mechanical properties
Investigations into corrosion/creep interactions in high temperature alloys exposed to corrosive environments are reviewed. After considering problems met in creep testing in aggressive environments, the influence of oxidising, carburising and sulphidising conditions encountered in single or multicomponent environments is discussed. Emphasis is put on the sulphur/creep interaction which forms the most challenging problem for industrial processes. This includes an analysis of oxide scale behaviour under stress and the influence of stress on corrosion. Knowledge of effective degradation mechanisms and the influence of oxidising atmospheres on creep properties, including pre-exposure, is still incomplete. However, corrosion-creep interactions attributed to carburising conditions appear to be established. Carburisation of high temperature alloys is a simple corrosion process, particularly when the equilibrium stage is reached.
