Welding and joining of advanced dissimilar lightweight alloys


   Faculty of Engineering and Informatics


About the Project

The automotive industry’s interest in the use of lightweight materials has significantly increased in recent years due to an enhanced demand for fuel efficiency and clean green technologies that improve environmental conditions. A major industrial challenge in the automotive industry relates to the joining of dissimilar materials. Which includes; the dissimilar/hybrid joining of materials such as; aluminium, steel, high strength steel, composites, and thermoplastics.

The existing challenge in joining dissimilar metals includes differences in the thermo-kinetic and mechanical properties of the material such as; crystal structure, melting point, and thermal conductivity. This project explores the novel application of nanotechnology to advanced joining techniques/additive manufacturing as methods of improving the deposition rates and the bonding between each layer for potential applications with dissimilar metals.Currently, all quality assessment of dissimilar joints/welds is conducted using destructive testing techniques. Unfortunately, these techniques are time-consuming and costly.

The proposed research will bridge the gaps in the existing knowledge on the dissimilar joining of ultra-high-strength materials and materials of complex chemical properties.


Funding Notes

This is a self-funded PhD project; applicants will be expected to pay their own fees or have a suitable source of third-party funding. A bench fee may also apply to this project, in addition to the tuition fees. UK students may be able to apply for a Doctoral Loan from Student Finance for financial support.
