Abstract

Superplastic forming and diffusion bonding are a key technology for application of gamma titanium as potential structural materials in hypersonic aircraft. Grain refinement is the primary requisite for superplasticity. Thermomechanical processing has been developed and applied to ternary alloyed gamma titanium aluminides for microstructure control. The fine-grained microduplex materials can be deformed superplastically more than 400% in tensile testing at 1473 K. Microstructural aspects of the superplastic behavior have been characterized in term of the morphology of two phases in a gamma titanium aluminide based alloy.
