Summary

Pure mode-I, pure mode-II and mixed-mode fatigue, creep and creep/fatigue crack growth tests have been carried out on Jethete M152, an aeroengine casing material, at 550°C. A reasonably good correlation of the creep crack growth rates was obtained using the C* parameter. Simple superposition of fatigue and creep crack growth results underestimates the creep/fatigue crack growth rates.
