Transmission electron microscopy investigation of the deformation mechanisms of nanostructured materials. Structural materials with high strength and high ductility are desirable because high strength allows structural components to carry high load and high ductility is essential to prevent catastrophic failure. The combination of high strength and high ductility has never been achieved in coarse-grained materials but has been realized in some nanostructured materials. This project aims to unde ....Transmission electron microscopy investigation of the deformation mechanisms of nanostructured materials. Structural materials with high strength and high ductility are desirable because high strength allows structural components to carry high load and high ductility is essential to prevent catastrophic failure. The combination of high strength and high ductility has never been achieved in coarse-grained materials but has been realized in some nanostructured materials. This project aims to understand the mechanisms responsible for the combined high strength and high ductility in nanostructured materials. The results obtained from this research will be very important for guiding the structural design of materials with high strength and high ductility which will find a wide range of civil and defence applications.Read moreRead less

Novel structure and the associated unique properties of nanostructured materials confer potentials for their exciting industrial applications, such as drug delivery to specified locations for cancer treatment, exceptionally high sensitivity sensors, miniaturisation in computers/electronic/communication industry, nano electro-mechanical systems, catalytic applications and exceptionally high strength materials. In most of the applications, the nanomaterials have to demonstrate acceptable corrosion resistance in the operation environment. However, corrosion resistance of nanostructured materials has not been investigated. The proposal will investigate the mechanistic aspect of localized corrosion and cracking of nanostructured materials.Read moreRead less

High strength light alloys are nanostructured materials, deriving their mechanical properties from nanoscale dispersions of strengthening precipitate phases controlled by alloy composition and thermomechanical processing. Atom-probe field-ion microscopy and high-resolution electron microscopy will be combined to study the aggregation of solute atoms that precedes formation of the precipitate phases. Experimental studies at high spatial resolution will be complemented by elastic strain energy calculations and first-principles modelling of the aggregation behaviour, to define its role in controlling precipitation processes and thus properties. The work will provide a basis for improved alloy design and a platform for computer-aided design of high-performance alloys.Read moreRead less

This project aims to establish a state-of-the-art in-situ nanomechanical testing capability for materials under extreme environments. A cutting-edge nanoindentation stage with customisable modules, as well as an optimally configured scanning electron microscope, will enable this capability for the first time in Australia. The expected outcomes will provide valuable insights into how microstructures affect mechanical properties at temperatures ranging from -150 to 1000 °C, strain rates from 10E-5/s to 10E5/s, and liquid environments. The resulting knowledge will guide the development of structural materials that withstand harsh environmental conditions, thereby advancing Australia's advanced manufacturing and sustainable energy sectors.Read moreRead less

One of the major research strengths of Australia is surface science as it is important for both fundamental and industry related research. In many cases it is crucial to investigate the outermost layer of a material or mineral. Metastable Induced Electron Spectroscopy is an ideal technique as it is sensitive exclusively to the outermost layer of a broad range of samples. The information gained is not accessible by any other method. The proposed equipment will be the first of this type in Australia and will complement existing surface science facilities. The project will enhance Australia's position in surface science internationally and a large number of projects will benefit from access to the equipment.Read moreRead less

The aim of this project is to generate a complete scientific understanding of a new generation of hybrid, tri-layered, optically-selective coatings. The new design paradigm combines the very different attributes of smooth and nanostructured layers so that superior and simultaneous control of both spectral and angular properties of light can be achieved. Existing theory will be extended so that quantitative analyses of these new systems and other hybrids become possible and new and improved fabrication techniques will be developed. The work will unlock new technological possibilities for coating performance and application and is likely to be associated with significant improvements in energy conservation and generation.
