About the Project

Reuse of metallic components at the end of their previous service is the most effective approach to increase resource efficiency and to mitigate environmental damage, and thus represents a preferred route to deliver full metal circulation. Reuse conserves all the embedded energy and other valuable resources used to manufacture components and keeps such energy and resources in the resource loop for much longer (slow down the loop). However, analogous to human beings, metallic components suffer from fatigue after prolonged service. It is estimated that more than 80% of metallic components at the end of their service have perfect physical dimensions but reduced mechanical performance due to the existence of flaws such as microcracks or corrosion-induced intergranular fissures, which all originate from fatigue.

Such used components can be effectively reused if the incipient cracks and sub-critical defects can be healed and the internal stresses accumulated during the service can be released without affecting the overall microstructure of the component. This PhD project aims to understand fatigue damages at a microstructural level and recovery of such fatigue damages.


The successful candidate is required to have a first-class or upper second-class honour degree in metallurgy, materials science or a related field of physical science or engineering etc. A Master’s level qualification is desirable but not essential.

How to apply

Please email (1) an up-to-date CV, (2) a single-page (A4), single-spaced personal statement setting out why you are interested in undertaking this project, (3) names and contact details of three referees, and (4) a copy of your highest degree certificate and transcript to [Email Address Removed]

Research journey

Doctoral research programmes (PhDs) take a proud place in the world-class research environment and community at Brunel. PhD students are recognised and valued by their supervisors as an essential part of their departments and a key component of the university's overall strategy to develop and deliver world-class research.

A PhD programme is expected to take 3 years full-time or 6 years part-time, with intakes starting in January, April or October.

The general University entrance requirement for registration for a research degree is normally a First or Upper Second Class Honours degree (1st or 2:1) or an international equivalent. A Masters degree is a welcome, but not required, qualification for entry.

Research support

Excellent research support and training

The Graduate School provides a range of personal, professional and career development opportunities. This includes workshops, online training, coaching and events, to enable you to enhance your professional profile, refine your skills, and plan your next career steps as part of the Researcher Development Programme. The researcher development programme (RDP) offers workshops and seminars in a range of areas including progression, research management, research dissemination, and careers and personal development. You will also be offered a number of online, self-study courses on BBL, including Research Integrity, Research Skills Toolkit, Research Methods in Literature Review and Principles of Research Methods.

Library services

Brunel's Library is open 24 hours a day, has 400,000 books and 250,000 ebooks, and an annual budget of almost £2m. Subject information Specialists train students in the latest technology, digital literacy, and digital dissemination of scholarly outputs. As well as the physical resources available in the Library, we also provide access to a wealth of electronic resources. These include databases, journals and e-books. Access to these resources has been bought by the Library through subscription and is limited to current staff and students. 

Dedicated research support staff provide guidance and training on open access, research data management, copyright and other research integrity issues.

Careers support

You will receive tailored careers support during your PhD and for up to three years after you complete your research at Brunel. We encourage you to actively engage in career planning and managing your personal development right from the start of your research, even (or perhaps especially) if you don't yet have a career path in mind. Our careers provision includes online information and advice, one-to-one consultations and a range of events and workshops. The Professional Development Centre runs a varied programme of careers events throughout the academic year. These include industry insight sessions, recruitment fairs, employer pop-ups and skills workshops.
