Abstract

Recent advances in aerospace materials technology are reviewed with emphasis on high temperature engineered materials and various forms of composites. The fatigue-creep-environment interaction models that are currently used for fatigue crack growth analysis at high temperatures13; are briefly reviewed. A linear superposition model is presented which is capable of accurately predicting the fatigue crack growth rate of Ti-24Al-11Nb (alpha-2) at 649 C and Ti-1100 at 593 C.
