The current understanding of environmental fatigue damage in turbine materials is limited. It is understood that crack nucleation and propagation as well as crack tip embrittlement is not solely associated with mechanical cyclic damage but there is an environmental assisted stress-oxidation sensitivity. The large and short crack growth phenomena in nickel superalloys are well documented both experimentally and in modelling, however, the role of the environment, particularly multi-oxidants, has still to be modelled as has the accumulated oxidation and fatigue-creep damage, which is still lacking. Hence, there is a need for methods that predict the onset of such damage and provide a means of better predicting crack nucleation in critical turbine components.

The project aims to develop a unified oxidation-fatigue crack model for next generation of nickel-based turbine materials both coated and surface mechanically treated. The developed model will be achieved by physics-based and experimental data driven, and will be validated by environmental test data generated in this project and advanced inspection techniques. The tests will be carried out using the Cranfield University state-of-the-art High Temperature Corrosion facilities. The successful candidate will have the opportunity to work alongside our industrial partners and gain significant learning experience, networking and present at conferences.
