TURBO POWER Project Analyzes Fatigue Behavior of Inconel 718 in Gas Turbine Applications
The TURBO POWER project is examining the effects of high temperature hold times on the fatigue life of Inconel 718, a nickel-based superalloy used in gas turbines. The research focuses on mean stress relaxation, initial softening at intermediate temperatures, and fatigue crack propagation, aiming to develop tools for improved fatigue design in gas turbine applications. The project's findings are presented in a theoretical framework and four accompanying research papers.

The TURBO POWER project investigates the influence of high temperature hold times on the fatigue life of Inconel 718, a nickel-based superalloy. The project aims to develop tools for designing against fatigue in gas turbine applications.
It studies the constitutive behavior of Inconel 718, focusing on mean stress relaxation and initial softening at intermediate temperatures. Additionally, it examines fatigue crack propagation behavior during high temperature hold times to establish a foundation for fatigue crack propagation modeling. The thesis is divided into two parts: the first part outlines the theoretical framework, including basic constitutive and fatigue crack propagation behavior, while the second part comprises four included papers detailing the research findings.
