An analytical, phenomenological version of the successful "edge-to edge" matching approach to the morphology and crystallography of diffusion-controlled phase transformations will be developed. This will be incorporated in a Windows based computer program that can predict the essential features of precipitation (orientation relationships, habit planes, morphology and interface structure), from readily available input data for the two phases involved. It will provide a fuller understanding of diffusion-controlled phase transformations and the computer simulation will assist in the development of improved precipitation hardening alloys. In addition, a database of crystallographic data for typical metallic materials will be established in the project.Read moreRead less

Summary
High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such c ....High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such circumstances. The proposed new high rate testing system will significantly advance research in this area. The facility will directly support a range of research projects in material and structural design in military and civil vehicles, aerospace industry and defence.Read moreRead less

Through an integrated and interdisciplinary approach, the exploitation of technologies arising from the research programme will be explored. In addition to the academic community, these technologies will benefit hi-tech industries including pharmaceutical and fine chemicals concerns which will gain from the application of the proposed compounds to chemical synthetic methodologies. Moreover, bio-inorganic chemists will have access to new classes of chemical compounds that could mimic the action of enzymes in nature.Read moreRead less
Resolution of the Pb-diffusion in monazite paradox using a high-temperature contact aureole environment. This research will enhance our understanding of the thermal evolution of ancient mountain belts through time. Australian geoscientists are recognized internationally for their contributions to this field and the result from this study will further enhance our understanding of the evolution of Australia's crust. Because numerous ore deposits throughout Australia are hosted in ancient rocks, ....Resolution of the Pb-diffusion in monazite paradox using a high-temperature contact aureole environment. This research will enhance our understanding of the thermal evolution of ancient mountain belts through time. Australian geoscientists are recognized internationally for their contributions to this field and the result from this study will further enhance our understanding of the evolution of Australia's crust. Because numerous ore deposits throughout Australia are hosted in ancient rocks, documenting the timing of mineralization with respect to the thermal evolution of the host rocks may help to predict the location of mineral deposits in these settings; and each new mineral discovery contributes to the future prosperity of Australia and its communities.

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 method to be used involves controlling the hot deformation of the steel and control of the phase transformation during or after deformation. Current work has shown that it is possible to reduce the grain size from 5 to 1microns using quite simple methods.Read moreRead less
Hot Rolling Model for Control of Nb Bearing Steels. High strength Nb bearing strip steels are used to reduce the weight of automotive and construction products. The manufacture of these steels is challenging because of difficulties encountered in maintaining constant properties and strip thickness. The aim of the current work is to develop a model for Nb bearing steels that describes the effect of processing conditions and composition on the microstructure evolution during hot rolling. The model ....Hot Rolling Model for Control of Nb Bearing Steels. High strength Nb bearing strip steels are used to reduce the weight of automotive and construction products. The manufacture of these steels is challenging because of difficulties encountered in maintaining constant properties and strip thickness. The aim of the current work is to develop a model for Nb bearing steels that describes the effect of processing conditions and composition on the microstructure evolution during hot rolling. The model to be developed will incorporate a new approach to describing dynamic recrystallization and will lead to better property and dimensional control. It will also assist in new grade development.Read moreRead less

Mineral products currently provide a great deal of Australia's exports to international markets, and underpin much of our economy. However, Australia can only maintain this position through continued improvement of mineral discovery rates, particularly for high value, deep earth resources. This project aims to improve the likelihood of the discovery of higher value hydrothermal orebodies. This will improve the value of mineral exports, raise exploration levels in some Australian provinces (thus stimulating economic activity in regional and industrial sectors), and help invigorate training within the geoscience arm of the university sector.
