Abstract:

The objectives of this three-year program were to establish how microstructure and loading rate influence the fracture behavior of Ti-10V-2Fe-3Al, a promising advanced titanium alloy increasingly used in aircraft structural components, and to relate the macroscopic fracture toughness results to microdeformation and microdamage processes with a view toward developing microstructurally based fracture models. Such models are desirable to develop compositions and processing conditions resulting in optimum mechanical properties.
