Experimental and crystal plasticity studies of deformation and crack nucleation in a titanium alloy

Describes the unique performance of titanium alloys undergoing cold creep or dwell sensitivity, mechanisms controlling the design and lifing of critically stressed titanium components in gas turbines. Fundamental mechanical understanding was derived from various EPSRC projects and a private venture investigation from Rolls-Royce (“Red Top 50”) researching component processing / safety implications of dwell fatigue – a prestigious invitation to a University academic to contribute towards a programme under International FAA review. Dunne at Oxford University utilized the empirical data in a crystal plasticity FE code to validate the quasi-cleavage facet model previously proposed by Evans & Bache from Swansea.
