They have been incorporated into a wide range of industrial, medical and domestic applications. The newest, known as PZN-PTs, are only available as single crystals. They have ten times the response of conventional piezoelectric materials, however they are expensive, mechanically fragile and have shape limitations. This project will tailor nanostructured intermediate states that will allow the production of stronger, more versatile polycrystalline PZN-PT ceramics. It will develop scientific results on nanocrystalline processing applicable to many materials and allow deeper insight into the mechanism of the anomalous piezoelectric response of these materials.Read moreRead less

Combustion Synthesis of Ternary Carbides. Ti3SiC2 belongs to a group of ternary carbides that exhibit an exciting combination of the high temperature properties of ceramics, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, however a cost effective large scale synthesis method has been lacking. Combustion synthesis, which uses the heat of reaction as the primary energy source, has great potential for this purpose. This program ....Combustion Synthesis of Ternary Carbides. Ti3SiC2 belongs to a group of ternary carbides that exhibit an exciting combination of the high temperature properties of ceramics, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, however a cost effective large scale synthesis method has been lacking. Combustion synthesis, which uses the heat of reaction as the primary energy source, has great potential for this purpose. This program will use advanced in-situ neutron diffraction experiments to map and quantify combustion synthesis reactions in the Ti-Si-C system and related systems. The results of these studies will be used to design methods of production for Ti3SiC2 and related materials.Read moreRead less
New Paradigm for Materials Technology for AZS Glassmaking Refractories. The project aims to enable the inexpensive manufacture of widely used refractories with reduced energy and materials costs and improved thermal and mechanical properties. The project plans to exploit technology patented by the researchers to fabricate percolated mullite materials from fly ash by sintering, yielding properties equivalent or superior to those of fuse-cast alumina-zirconia-silica refractories (AZS).

The project aims to enable the inexpensive manufacture of widely used refractories with reduced energy and materials costs and improved thermal and mechanical properties. The project plans to exploit technology patented by the researchers to fabricate percolated mullite materials from fly ash by sintering, yielding properties equivalent or superior to those of fuse-cast alumina-zirconia-silica refractories (AZS). AZS is expensive since it requires melting by fuse-casting and high-purity raw materials. The project aims to eliminate both requirements by sintering and use of waste fly ash, giving microstructures of dense, direct-bonded, percolated, mullite, single crystals, with residual impurities in the interstices that do not affect creep.Read moreRead less

Advances in modern technology and a competitive manufacturing industry depend critically on new and improved materials. The pace of change is rapid, and many countries are taking steps to improve and coordinate developments. Australia has a very successful record of materials research and innovation and is developing a substantial infrastructure in the area. However, the materials research community is scattered, and research effectiveness is sometimes lessened by a lack of critical mass. This network will bring together university, government and industry researchers, and promote collaborative research, access to each other's facilities, staff and student exchanges, improved access to existing infrastructure and coordinated planning for new acquisitions.Read moreRead less

This proposal seeks to establish a multi-functional system for investigating surface, interface, and thermal properties of functional materials. The instrumentation features thermo-gravimetric, infra-red imaging hyphenated with gas-chromatography-mass spectrometry. The expected benefits are an enhanced research capability in solid-electrolyte-interphase and electrolyte decomposition on electrodes being used in alkaline-ion batteries, which could potentially pose risks during manufacturing and application. The system will not only facilitate high-quality research and impact the training of young researchers, but also provide a platform from which to enhance Australian materials research capabilities.Read moreRead less

The availability of suitable materials is a driver of new technologies. We will develop a new class of ternary and quaternary alloys with nanolaminate structures at the atomic scale using a combination of theoretical modeling, novel thin film synthesis and advanced characterization methods. The nanostructure of these materials is expected to promote a rare combination of metallic and ceramic like properties, such as low friction, high mechanical strength, resistance to heat shock, fracture, corrosion and oxidation, up to very high temperatures. Careful characterisation of the growth process and structure-property relationships will allow us to develop methods of tailoring the property mix for operation in harsh environments.Read moreRead less
