Modeling Creep-Fatigue-Environment Interactions in Stream Turbine Rotor Materials for Advanced Ultras


Project No: FE0005859


Project Description

Despite the importance of creep-fatigue-environment interactions, they are not well understood. The project will develop and demonstrate computational algorithms for alloy property predictions, and will model key mechanisms that contribute to the damage caused by creep-fatigue-environment interactions.

The project team will build upon existing expertise, data, and materials modeling tools to develop multiscale (time and volume) computational algorithms and guidelines to understand and predict the response of creep-fatigue-environment interactions and the chemical/mechanical response of nickel-based Haynes 282 superalloy at the temperatures and pressure ranges expected in an A-USC steam turbine.
