Analysis of high temperature fatigue lifetime of GH4133B superalloy used in turbine disk of aero-engine

Based on the S-H cavity model theory and the thermodynamic diffusion equation, the high temperature fatigue lifetime equation is deduced, and the influence of stress amplitude and mean stress on fatigue lifetime is quantitatively analyzed. At high temperature of 650°C, according to the test data of...
