| Abstract Scope |
Titanium alloys exhibit a large degree of scatter in fatigue life across a wide range of applied stress. Prior work has linked this variability to subtle variations in the microstructural neighborhoods where cracks nucleate and specifically the arrangement and interconnectivity of primary alpha particles that are suitably oriented for basal slip and faceted crack growth. This presentation will cover efforts toward the development of a pragmatic mechanism-based model for cyclic fatigue crack growth. The model considers crack nucleation from basal slip bands, microstructural effects on small crack growth rates, and seamlessly transitions to long crack growth to the point of failure. |
