Application of a simple statistical spalling model for the analysis of high-temperature, cyclic-oxidation kinetics data

A statistical cyclic-oxidation model is presented. This model gives analytical formulas to assess stabilized metal consumption in cyclic-oxidation experiments. The model is first detailed, then applied to several Ni-base superalloys, which form an a-alumina scale during oxidation above 1000degreesC. A new map is introduced in order to compare the cyclic-oxidation behavior of these alloys.
