Alloys-by-design: Application to titanium alloys for optimal superplasticity

Abstract:

An alloy design approach for titanium alloys is presented. New alloys are isolated, manufactured and tested with an emphasis on the superplastic response. The superplastic effect is found to be optimal between 650 to 750∘C at strain rates between 8.3×10−2 and 8.3×10−3/s – this is a substantial improvement in terms of temperature and deformation rates over traditional titanium alloys such as Ti–6Al–4V. Elongations approaching ∼2000% are demonstrated. Electron backscatter diffraction studies co...
