This project investigates a new approach to engineering alloy design that explicitly takes into account, and exploits, the energy delivered into an alloy during deformation processing. The work intends to resolve fundamental questions concerning the effect of deformation processing of the evolution of the material structure and the effect this structure has on the resulting mechanical and corrosion properties. The new structures resulting from this approach are remarkably fine and uniform suggesting they will be both strong and corrosion resistant. The proposed work intends to uncover the origins of both these structures and new properties, and exploit them for the design of new engineering alloys with greatly improved properties.Read moreRead less
Unlocking the twinning stress: confidence inspiring light alloys. The ultimate aim of this research is to reduce fuel consumption through weight reduction. It will achieve this by increasing the performance of the lightest structural metal, magnesium. Contrary to the metals it typically replaces (steel and aluminium), magnesium fails via mechanisms that involve deformation twinning.

The ultimate aim of this research is to reduce fuel consumption through weight reduction. It will achieve this by increasing the performance of the lightest structural metal, magnesium. Contrary to the metals it typically replaces (steel and aluminium), magnesium fails via mechanisms that involve deformation twinning. Better understanding of twinning is needed to enhance performance and give automotive makers confidence to apply the metal more widely. The applicants have recently found evidence that a key missing piece of the puzzle is the role of plastic relaxation. The proposed work will use this idea to develop a new fundamental understanding of twinning using novel in-situ diffraction and modelling techniques.Read moreRead less
A new paradigm for creating fatigue-resistant light metals. Ninety per cent of failures of metal components are caused by fatigue. Fatigue arises from cycles of alternating stress during service which lead to failure at stress levels surprisingly short of the material's static strength. Fatigue is the 'Achilles heel' of complex engineering alloys and places significant limitations on adopting new lightweight solutions for improvements to fuel efficiency in transportation. Aluminium alloys in par ....A new paradigm for creating fatigue-resistant light metals. Ninety per cent of failures of metal components are caused by fatigue. Fatigue arises from cycles of alternating stress during service which lead to failure at stress levels surprisingly short of the material's static strength. Fatigue is the 'Achilles heel' of complex engineering alloys and places significant limitations on adopting new lightweight solutions for improvements to fuel efficiency in transportation. Aluminium alloys in particular have notoriously poor fatigue performance. This project aims to develop a new class of fatigue resistant light alloys whose properties improve, rather than deteriorate, during service. This development is based on a new understanding of the coupling of microstructure evolution and deformation.Read moreRead less

This project aims to design new, environmentally friendly coating systems for steel in marine environments by incorporating novel, non-toxic pigments that can be combined to protect against both corrosion and microbial attack.

The components may themselves be dual active, or be combined to capitalise on individual protection mechanisms that provide a synergy whereby the combination leads to better protection outcomes. Such coatings have the potential to significantly improve the lifetime of marine infrastructure.Read moreRead less
