PhD Studentship: Understanding deformation of heat resistant superalloys and structures made by laser-based additive manufacturing

A 3.5 years studentship is available to study 3D printed aerospace superalloy structures in the School of Metallurgy and Materials at the University of Birmingham (UoB), a global top 100 institution. This project will be supervised by Dr Yuanbo (Tony) Tang.

This PhD project is an exciting opportunity for a self-driven individual with a passion for advanced manufacturing and metallurgical research. The PhD researcher will develop a comprehensive understanding of the deformation behaviour of superalloy structures at high temperatures (up to 1200 degC), he or she will also rationalise their behaviour by developing computational based physical models. During this project, the PhD researcher will gain firsthand experience in additive manufacturing and innovative mechanical testing facilities, supported by training provided by technical experts. The PhD candidate will also learn and operate cutting edge electron microscopes at UoB.

Superalloys and Additive Manufacturing

Nickel-based superalloys are one of the most chemically complex materials that is ever designed by humankind. It typically takes the precise blending of more than 10 elements to confer the targeted properties. They are mission-critical, primarily used for aerospace applications, such as the hot section in jet engines. Over the 80 years, this class of alloys have evolved tremendously and the recent development in additive manufacturing (or 3D printing) has allowed further engineering possibilities.

The microstructure of the additive manufactured superalloys differs largely from the conventionally manufactured counterparts. In order to enable life predictions and confident adoption of these materials, a fundamental understanding of the relevant deformation mechanisms is crucial. This project aims to test the additively manufactured superalloys at extreme conditions, with possible exposure to hydrogen environment as well. The outcome of the project will be highly industrially relevant and potentially engender strong impact on the Global Net Zero Initiative.

We are looking for candidates who:

1. Have obtained or will obtain a first class or upper-second-class degree in a relevant discipline such as materials, mechanical or civil engineering, condensed matter physics, or similar.
2. Are self-motivated, inquisitive and genuine

No prior experience in experimental or modelling work is required. However, candidate with relevant exposure to characterisation, additive manufacturing, modelling and engineering applications might be viewed favourably.

How to apply:

Please send an email to Dr Yuanbo (Tony) Tang (y.t.tang@bham.ac.uk) to explain your motivation and attach the following.

1. Resume (CV)
2. Academic transcripts

Funding notes:

Funding is available for home (UK) students covering home fees (~£4.2k pa) and a stipend (~£18.6k pa) for 3.5 years. For international students, this will only cover the home fees portion and stipend but NOT the full overseas fees. Fully self-funded students (with an external scholarship for example) are also encouraged to apply.
