New Wrought Magnesium Alloys: Manipulating the Annealed Microstructure. One of the main impediments to increased use of wrought magnesium is its characteristic but mediocre mechanical properties. The proposed work paves the way for new improved wrought magnesium alloys by determining how the constituent nano-structures, micro-structures and deformation conditions can be manipulated to control the evolution of properties during annealing.

The proposed work paves the way for new improved wrought magnesium alloys by determining how the constituent nano-structures, micro-structures and deformation conditions can be manipulated to control the evolution of properties during annealing. The project will deliver mathematical models describing the annealed microstructure and mechanical properties. The work will also explore the potential of a recent discovery made by the CI of a simple technique to randomise the alignment of the annealed atomic lattice structure, which promises to markedly improve formability.Read moreRead less
Modelling twinning transitions in light metals: a new foundation for alloy and process development. Australia's quest to become a world leader in light metals technology is being held back by a lack of quantitative understanding of the metallurgical behaviour of magnesium, which is the lightest engineering metal, and titanium, which is the strongest light metal. In particular, there is poor knowledge of the influence of material parameters on deformation twinning. This knowledge is vital for eff ....Modelling twinning transitions in light metals: a new foundation for alloy and process development. Australia's quest to become a world leader in light metals technology is being held back by a lack of quantitative understanding of the metallurgical behaviour of magnesium, which is the lightest engineering metal, and titanium, which is the strongest light metal. In particular, there is poor knowledge of the influence of material parameters on deformation twinning. This knowledge is vital for efficient production and optimised alloy and part design. This proposal aims to develop a quantitative understanding of transitions in twinning activation for improved performance in fatigue, crash behaviour, structural integrity, forming, forging, extruding, hot rolling and annealing.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
Ultra-lightweight alloys with unique multi-dimensional property profiles. Lightweight alloys with high specific-strength are an essential prerequisite in modern and future technologies. To be useful, they must also possess ductility and inherent corrosion resistance. The latter two properties, however, are inversely correlated with strength. This project proposes to break this paradox - not only in terms of a paradigm change regarding multi-property alloy design - but as applied to the most ligh ....Ultra-lightweight alloys with unique multi-dimensional property profiles. Lightweight alloys with high specific-strength are an essential prerequisite in modern and future technologies. To be useful, they must also possess ductility and inherent corrosion resistance. The latter two properties, however, are inversely correlated with strength. This project proposes to break this paradox - not only in terms of a paradigm change regarding multi-property alloy design - but as applied to the most lightweight engineering alloy system in existence, Magnesium-Lithium (Mg-Li), for which the impact on specific properties is immense. The aim is to develop ultra-lightweight Mg-Li based alloys with formidable property profiles via alloy design and thermomechanical processing. The expected outcome is a new class of structural corrosion resistant metal.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
