Thermo-mechanical Fatigue Crack Propagation in Inconel 718
Thermo-mechanical fatigue crack propagation in Inconel 718 has been studied with different methods. In-situ observations with a scanning electron microscope (SEM) were performed, the crack propagation process was followed cycle by cycle and the influences from load, temperature, and microstructure on the crack growth were analyzed. To measure the displacements an image analysis technique was devel
