PhD Studentship sponsored by Rolls-Royce plc Strong,
Tough and Fatigue-Resistant Steel for Elevated Temperature Applications
Department of Materials Science and Metallurgy
This is a project in collaboration with Rolls-Royce plc, a world leading company in the aerospace industry. The project aims are to develop a novel steel capable of sustaining stresses in excess of 1100 MPa at 600C for short durations, whilst at the same time having the toughness, fatigue resistance and strength to meet design requirements at ambient temperatures. There is no existing material which fits into this scenario.
We shall use physical metallurgy principles in order to develop the alloy. The key concept is to make marageing steels capable of resisting creep deformation at 600C. This will require alloy design to avoid excessive reversion to austenite and to introduce appropriate particles to hinder dislocation creep.
About half the work will be experimental, involving both validation of the fundamental aspects, and in association with design engineers, validation on production facilities. Detailed characterisation experiments will involve a variety of microscopy techniques as well as mechanical testing.
This project will be supervised by Professor H. K. D. H. Bhadeshia who will be pleased to answer questions about the project (hkdb@cam.ac.uk).
Prospective applicants can consult the Phase Transformations and Complex Properties Group web site for further information on the research activities of this group.
The project is fully funded at the 'home fees' rate. Students who are eligible to pay 'overseas' rate fees must be able to meet the extra costs from their own resources. Applicants should have (or expect to be awarded) an upper second class UK honours degree, or a lower second with a Master's, (or overseas equivalents) in a relevant subject.
Application forms and the Graduate Studies Prospectus are available from the Board of Graduate Studies web site and copies of these documents are available via www.admin.cam.ac.uk/univ. Further information on the application process is available from Dr Rosie Ward (remw2@cam.ac.uk).
