Abstract: This paper presents a comprehensive analysis of thermo-mechanical fatigue (TMF) in high-temperature superalloys used in gas turbine applications. TMF is a critical factor affecting the lifespan and performance of gas turbine components, which operate under cyclic thermal and mechanical loads. This study investigates the mechanisms of TMF, the material properties of superalloys that influence their fatigue behavior, and the methods for evaluating and mitigating TMF damage. Advanced characterization techniques and computational modeling approaches are employed to gain insights into the fatigue mechanisms and predict the lifespan of turbine components.
