Understanding grain boundary segregation - a route to developing new advanced engineering materials. This project will investigate atomic-scale grain boundary segregation - one of the most important factors influencing the properties of engineering alloys. This will be applied in the development of new Ti, Zr and nanocrystalline alloys with a large potential market and for which Australia is extremely well positioned to become a major producer.
Quantifying the role of impurities in nanocrystalline metals. This project aims to create new designer nanocrystalline materials with applications in aerospace, transportation and medical devices through the controlled addition of impurity elements. This project will investigate and predict the fundamental role of these impurities to be able to tailor the mechanical properties to particular applications.
Interactions between linear and interfacial crystalline defects and their impact on mechanical properties in nanostructured metals and alloys. The project aims to apply in-situ deformation transmission electron microscopy to investigate the interactions among crystalline defects in nanostructured metallic materials and to explore the effect of the interactions on mechanical properties. The results will guide the structural design of nanomaterials with superior mechanical properties.

A tool to observe nanoscale deformation by transmission Kikuchi diffraction:
This project seeks to establish an advanced in-situ characterisation capability for understanding the nanoscale processes that govern the properties of materials and how microstructures change during straining. A custom-designed mechanical straining device will operate within a scanning electron microscope configured for orientation mapping with the new technique of transmission Kikuchi diffraction. The facility, which would be the first in the world, is designed to have a very high spatial structural resolution of only a few nanometres for crystal orientation mapping and can be operated at temperatures up to 400 °C. The resulting knowledge may provide guidance for the design of structural materials and materials processing with applications in aerospace, transportation and medical devices.Read moreRead less

Enabling a new generation of advanced high-strength aluminium alloys through materials design. This project will create an analysis-engine of novel atom-sensitive methods to unlock the materials science of hierarchy-strengthening. It will assist in determining how hierarchical structures evolve and synergistically strengthen a new generation of advanced high-strength aluminium alloys that are strong as steel, but a third the weight.

However, the exact contribution of individual grain boundaries to mechanical properties is not well understood, affecting advanced materials design. This project will use in-situ deformation transmission electron microscopy techniques to reveal how individual grain boundaries deform and interact with dislocations, and to link directly the structures and orientation of individual grain boundaries with mechanical behaviours. Expected results are better structural design of advanced metallic nanomaterials with superior mechanical performance.Read moreRead less
