Modelling of High Temperature Oxidation of Alumina-Forming Single-Crystal Nickel-Base Superalloys

Abstract:

Microstructure evolution in single-crystal superalloys is modelled as the interplay between oxide growth and substrate response. This is of particular importance for specimens with reduced wall thicknesses, where the affected substrate constitutes a significant fraction of the material. A model based on thermodynamic and kinetic data only is presented in order to predict the growth kinetics of oxides and the resulting influence on microstructure evolution of the substrate. The present work fo...
