Smart Materials Between Two and Three Dimensions. Shape-memory alloys involving martensitic transformations, are important as smart materials. Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. ....Smart Materials Between Two and Three Dimensions. Shape-memory alloys involving martensitic transformations, are important as smart materials. Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. This project addresses these issues using model materials in thin-film and bulk-crystal forms. Capacitance dilatometry, optical, electron and scanning-probe microscopies, and x-ray techniques, will unlock an understanding of the physical and metallurgical conditions controlling these transformations.Read moreRead less
Development of ultrafine Grained Steels. This project will develop new methods to produce steels with much finer microstructures, and investigate how these microstructures form. This will markedly increase the strength and toughness of these steels, which is particularly required for the pipeline, off shore platform and large construction industries. The method to be used involves controlling the hot deformation of the steel and control of the phase transformation during or after deformation. ....Development of ultrafine Grained Steels.

The desire to reduce the weight of automobiles due to legislative requirements on fuel emissions and to reduce overall fuel consumption is the driving force behind research into the development of new Mg-based alloys to replace the heavier steel and Al-alloy components in automobiles. Given the enormous worldwide transportation market and the environmental and legislative motivation for reducing fuel emissions, the development of new Mg-based alloys capable of meeting this demand from automotive manufacturers represents both a potentially large economic advantage to the country of development as well as helping to address the environmental concern about fuel emissions.Read moreRead less

This project aims to engineer electrolyte materials, based on organic ionic plastic crystals, and use isomeric doping to improve the ionic conductivity. The development of safer batteries relies on eliminating the volatile and flammable solvents commonly used as the electrolyte. Improving the safety and performance of batteries is important as electricity costs increase. Solid state ionic electrolytes can address leakage and volatility problems, but the conductivity must be improved if these materials are to support high battery power. The project’s electrolyte materials can be used in lithium metal batteries, which have higher theoretical energy densities than traditional lithium ion batteries. This project will develop new solid state electrolytes, with improved conductivity, and use these materials in emerging lithium battery technologies.Read moreRead less
