Summary on Grant Application Form |

The proposed research combines a microstructural and scientific investigation of a high strength titanium aluminide alloy (of specified composition) with a rigorous engineering assessment of its mechanical properties against specific target engine components. The comprehensive mechanical testing programme will address tensile properties, creep, fracture toughness, total life under cyclic loading, fatigue crack growth resistance and the growth of small fatigue cracks. Microstructure-property relationships will be studied throughout the programme (and will include a brief assessment of the stability of microstructure at elevated temperature). Not only will the study define optimised microstructures for this alloy which is representative of an exciting new class of high strength titanium aluminides, but it will also provide quantitative data and understanding against which the continued development of such alloys for structural applications can be assessed. The study utilises a wide range of microstructural assessment techniques (to include in-0situ loading within a field-emission-gun scanning electron microscope and assessment of deformation within plastic zones local to fatigue crack tips using TEM) and innovative crack growth monitoring techniques (to include monitoring the growth of small (contained) cracks continuously). This combination of mirostructural characterisation and property assessment will also be used to guide the development of micromodels of behaviour.
