New Mechanistic Models of Creep-Fatigue Interactions for Gas Turbine Components
Performer: Purdue University
Project No: FE0011796
Program Background and Project Benefits
This project will develop novel tools to predict creep-fatigue crack growth in nickel-based gas turbine alloys for stationary power applications. Incorporation of this new model into existing product life cycle management approaches at NETL has significant potential to reduce turbine manufacturing costs and maintenance costs through increased blade life, leading to lower plant costs and lower electricity costs. Specifically, this project will create and validate a robust, multi-scale, mechanism-based model that quantitatively predicts creep-fatigue crack growth and failure in the nickel-based gas turbine alloy IN 718.
