Project Overview:

An exciting opportunity to work as part of our Advanced Steel Research Centre (ASRC) at WMG, University of Warwick, an internationally leading centre for steel research. The ASRC is located in the new Advanced Manufacturing and Materials building and has benefited from a multi-million pound investment in new equipment.

Weld repair of power generation steels remains a vital part of the life management process. As power plants operate worldwide under ever more aggressive conditions with respect to both temperature and flexible operation (e.g. cycling) there is an increasing need to develop innovative weld repair procedures to mitigate damage. Materials which require repair include both traditional low alloy steels (such as Grades 11, 12, 22), creep strength enhanced ferritic steels (predominately Grades 91 and 92) and dissimilar metal welds (DMWs).

This project aims to link the as-simulated repair condition to the post-test condition using state-of-the-art advanced electron microscopy tools. Post-test samples include a range of cross-weld creep tests including large, feature type tests, repairs tested in pressure vessels and ex-service repairs. A key goal of this project is to link the observed damage in the heat affected zone of the post-test repair welds to the observed distribution of particles, grain size/features and other relevant pre-test observations in the repair welds. This assessment is expected to have an enormous impact on the power generation industry and as such the student will be encouraged to communicate the results of this research project through worldwide conferences, workshops, key Code meetings and other venues. Publication of the research will be equally vital to this effort and the industrial partner is very keen to assist the student in writing and submitting publications to leading journals in the field.

The project provides an outstanding opportunity to be involved in cutting-edge research to optimize newly developed weld repair procedures for low alloy and 9%Cr CSEF steels for state-of-the-art power plants, and gives valuable exposure to a major area of industry. This project is expected to have an immense implications to the industry and is fully sponsored by the Electric Power Research Institute (EPRI).

Entry Requirements

Candidates should have a minimum of an upper second (2.1) honours degree (or equivalent) in Materials Sciences (including Metallurgy, Ceramics), Chemical Engineering, Chemistry, Geology or related disciplines. A good command of English is essential for the position.


Funding is available for UK/EU students. A stipend of £14,296 plus industrial top up of £3,000 will be paid per annum for 3.5 years.
