About the Project

Understanding the properties of new materials is essential in order to develop new and improved products. Materials engineers work at the forefront of new technology, with designers and engineers of every discipline, to push forward the boundaries of science and engineering.

The School of Metallurgy and Materials has over 120 Postgraduate Research Students carrying out projects in a broad range of topics in materials science and engineering, often in collaboration with, or based in industry. The quality of the research work in the Department of Metallurgy and Materials has been confirmed by our outstanding performance in successive Research Assessment Exercises.

For more information please visit http://www.eng.bham.ac.uk/metallurgy/research.shtml or contact the project supervisor.

Research Interests may include:

Localised Corrosion and Environmentally Assisted Fracture

Aluminium Alloys

Stress and Microstructure Effects on Localised Corrosion in Aluminium Alloys
Corrosion and Stress Corrosion Cracking of 7xxx Friction Stir Welds
Pit to Crack Transitions and Corrosion Fatigue characterisation in an Al-Li-Cu alloy
Corrosion and Stress Corrosion Cracking of Dissimilar Metal Friction Stir Welds

Funding Notes

This PhD is open to candidates with a minimum 2i Honours degree or its equivalent in Materials Science, Chemistry, Physics or Engineering. The University Graduate School is pleased to announce that it has ten Elite Doctoral Researcher Scholarships available for the 2012-2013 academic year. The Scholarships are available to outstanding overseas candidates of the highest academic aptitude holding an offer of a place to study on a PhD at the University of Birmingham starting in October 2012. International students can often gain funding through overseas research scholarships, Commonwealth scholarships or their home government.
