A computer program has been developed which simulates the cyclic oxidation behavior of materials. The simulation is based on the assumption that the weight fraction of scale that spalls in any thermal cycle is proportional to the amount of scale present on the surface at the beginning of the cycle. The program provides plots as well as tabular data which describe the cyclic oxidation behavior of a given material. Individual input parameters can be selectively altered and the resulting change in cyclic kinetics determined, allowing the user to quickly survey a wide range of cyclic conditions on the kinetics of a given material.
