Abstract

Several kinds of creep damage parameters, such as area fraction of cavities, fraction of cavities on grain boundary lines, areal cavity density, and A-parameter, have been proposed and examined for the lifetime assessment of high-temperature components. In this study, physical meaning of damage parameters is analyzed on the basis of a probabilistic model of creep cavities where spherical cavities with the same radius are randomly distributed on every grain boundary plane nearly perpendicular to the stress axis direction.
