Development of Creep Resistant TiAl Alloys for High Temperature Structural Applications. TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure ....Development of Creep Resistant TiAl Alloys for High Temperature Structural Applications. TiAl based alloys are being developed as high temperature structural materials for aerospace and automotive applications and thus their creep resistance (long-term strength at elevated temperatures) is critical. This project aims at developing creep resistant TiAl alloys through a combination of addition of rare earth and severe plastic deformation. It is expected that a refined and stablised microstructure consisting of submicron lamellar grains and nanosized lamellae be obtained. This will result in a highly creep resistant prototype TiAl material and leads eventually to the development of commercial TiAl alloys.Read moreRead less
Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specificat ....Failure Mechanisms of Roof Cladding under Fluctuating Wind Loads. Wind damage to low-rise buildings cause disruption to communities and result in economic losses. Improvements to the most vulnerable part (i.e. roof) will therefore have national benefits and associated economic benefits. Currently, roofing systems used in cyclonic areas are evaluated to DABM in the Northern Territory and to TR440 elsewhere, requiring the same product be tested under two different (and unsatisfactory) specifications. This is due to the limited understanding of wind-induced fatigue of cladding. This project will provide the framework for understanding and minimizing cladding fatigue. A realistic single test will also reduce cost and result in better design systems.Read moreRead less

This project involves characterisation using modern facilities of the form and identity of atomic-scale clusters of alloying elements in selected automotive sheet alloys that have been subjected to single and multiple ageing treatments and examination and modelling of deformation mechanisms and behaviour in such alloys. The aim is to establish the precise role of clusters of solute atoms and vacancies in the formation of precipitate phases that control the final strength and deformation behaviour of the alloys, and to provide useful guidelines for further improvements in strength of these alloys via the control of alloy composition and of multiple ageing treatments.Read moreRead less

Interactions between Lattice Defects and Nanoscale Solute Aggregates: Strengthening and Creep Mechanisms in Magnesium Alloys. Advances in manufacturing and processing technologies in recent years have brought renewed interests in magnesium alloys for applications at elevated temperatures (100-200°C).

Advances in manufacturing and processing technologies in recent years have brought renewed interests in magnesium alloys for applications at elevated temperatures (100-200°C). Improvement in strength and creep resistance of existing alloys and development of new alloys require better understanding of strengthening and creep mechanisms and their correlations with deformation behaviour of the alloys. In this project, advanced imaging techniques of transmission electron microscopy and three-dimensional atom probe field-ion microscopy, combined with tensile and creep tests, will be used to study interactions between lattice defects and nanoscale solute aggregates and their quantitative effects on deformation behaviour of magnesium alloys at elevated temperatures. The aim of this project is to develop a robust theory for the design of magnesium alloys with improved strength and creep resistance.Read moreRead less
CHARACTERISATION OF DIE CAST MAGNESIUM ALLOYS FOR AUTOMOTIVE POWER TRAIN COMPONENTS. A new group of magnesium die casting alloys has recently been developed for fabricating automotive power train components. While these alloys exhibit good tensile yield strength at both ambient and elevated (100-200°C) temperatures, they are prone to excessive creep deformation when exposed to moderate levels of loads at temperatures above 125°C. The aim of this project is to characterise microstructures of th ....CHARACTERISATION OF DIE CAST MAGNESIUM ALLOYS FOR AUTOMOTIVE POWER TRAIN COMPONENTS. A new group of magnesium die casting alloys has recently been developed for fabricating automotive power train components. While these alloys exhibit good tensile yield strength at both ambient and elevated (100-200°C) temperatures, they are prone to excessive creep deformation when exposed to moderate levels of loads at temperatures above 125°C. The aim of this project is to characterise microstructures of these alloys subjected to controlled levels of creep deformation in the temperature and stress regime of interests, with a view to identifying microstructural factors that are important in determining the creep resistance of die cast magnesium alloys. The outcome of this project will provide useful guidelines for further improvements in creep resistance of these alloys and development of new die cast alloys with higher creep resistance at elevated temperatures.Read moreRead less

Metal Processes and Products for a Sustainable Future. The metal manufacturing industry is extremely important to Australia; either directly through local products or indirectly through our mineral exports to the global market. The growth in emerging economies is driving major increases in metal production which currently requires large amounts of energy and production of significant greenhouse gas. Also many of the products, such as automobiles, are contributing to our environmental problems. ....Metal Processes and Products for a Sustainable Future. The metal manufacturing industry is extremely important to Australia; either directly through local products or indirectly through our mineral exports to the global market. The growth in emerging economies is driving major increases in metal production which currently requires large amounts of energy and production of significant greenhouse gas. Also many of the products, such as automobiles, are contributing to our environmental problems. This program of research will develop new processes, such as strip casting, that can radically reduce the production energy and other resource requirements. Also new products that will lead to lighter weight vehicles will be developed.Read moreRead less
Smart Materials Between Two and Three Dimensions. Shape-memory alloys involving martensitic transformations, are important as smart materials. Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. ....Smart Materials Between Two and Three Dimensions. Shape-memory alloys involving martensitic transformations, are important as smart materials. Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. This project addresses these issues using model materials in thin-film and bulk-crystal forms. Capacitance dilatometry, optical, electron and scanning-probe microscopies, and x-ray techniques, will unlock an understanding of the physical and metallurgical conditions controlling these transformations.Read moreRead less
