Summary
Probing the nanomechanics of single grain boundary with decorated solutes. Grain boundaries (GBs) are thermodynamically susceptible to attract solutes to reduce system energy. Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals.

Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals. Through correlative in-situ nanomechanical testing and atom probe tomography, this project aims to unravel the rationale of segregation behaviour of individual GBs and its effectiveness to enhance the material performance, and hence enable nanostructural design of advanced metallic materials with unprecedented properties.Read moreRead less

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.

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

Summary
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.
