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

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
