An empirical study to understand structural integrity in aerofoils subjected to foreign and domestic object damage (FOD/DOD), correlating fatigue performance to microstructure and impact geometries. The research was conducted under the EU Framework VI programme IMPRESS, a major European initiative to develop novel intermetallic alloys for energy applications. This mechanical assessment plus additional research under the EPSRC Strategic Partnership in Gas Turbines has underpinned the selection of TiAl for low pressure turbine aerofoils in future Rolls-Royce Trent 1000 engine derivatives, offering direct UK competition to the employment of gamma in US designed GEnX engines which entered service in 2012.
