Abstract
To increase efficiency, a wide range of energy-related applications is pushing components to higher temperatures where environmental degradation can be life limiting. Unlike mechanical properties such as creep, there is no simple degradation parameter to capture the time-temperature-thickness limitations of candidate alloys. An initial model has been proposed and additional work is in progress to validate the model with longer-term exposures at 900°C and modify the model to capture additional service parameters such as cycle frequency and the effect of water vapor. Additional issues are discussed including the minimum data required for a new alloy to be modeled in the proposed manner.
