Profile
Current Project
"Oxidation-Accelerated Crack Growth Behaviour for a Nickel-Based Superalloy", funded by the Faculty of Technolgy.
The project, in close collaboration with Rolls-Royce plc and the University of Cranfield, will focus on the study of oxidation-accelerated crack growth behaviour of a nickel-based superalloy for the latest Rolls-Royce aeroengine turbine disc applications. Both experimental and modelling work will be carried out towards a micro-mechanics based prediction of fatigue crack growth behaviour under the attack of oxidation. Experimental work includes high-temperature fatigue tests at Portsmouth and oxidation-damage measurements at Cranfield. Modelling work involves oxygen diffusion analyses coupled with mechanical deformation. The project will contribute to the development of a micromechanics-based life prediction model for a nickel-based superalloy under fatigue-oxidation conditions (EPSRC project).
