13th International Conference on Fracture June 16–21, 2013, Beijing, China -8- A a) b) c) Figure 10. Fracture surface, elevated temperature 450°C, build direction 0°, thermomechanical fatigue testing. Fracture is intercrystalline with crack branching as indicated by arrows in right figure. Area “A” is an area with poor bonding. B Figure 11. Fracture surface, elevated temperature 800°C, build direction 0°, thermomechanical fatigue testing. Fracture is intercrystalline with crack branching as indicated by arrows in right figure. Area “B” is an area containing an inhomogenity (partly molten particle).
