Summary
Novel anodic coating of magnesium alloy components for corrosion protection. This research aims to protect magnesium alloys from corrosion, paving a path for them to be used as auto and aircraft components. It will establish novel protective anodic coatings upon magnesium and thereby pioneer implementation of magnesium alloys more generally, as galvanising did for steels.
Growing a multi-scale internal structure: new wrought metals for energy conservation. This research aims to reduce the weight of wrought metal parts so that transport and machinery will use less energy. It will establish how to grow novel multi-scale internal structures and will thereby pioneer a new class of metals that display superior properties.
High performance cast magnesium alloys. Reducing the weight of cars, particularly their engines, enables substantial reductions in fuel consumption and greenhouse gas emissions. A new generation of magnesium alloys will be developed by this project for the manufacture of considerably lighter components with improved mechanical performance for powertrain and structural applications.
Biocompatible magnesium alloys with specific materials properties. This project aims to develop biocompatible magnesium alloys with highly desirable mechanical properties and degradation on demand, and the fundamental science to achieve the materials properties. Injured human bones often need biomaterials to restore function. This project’s magnesium biomaterials could change the biomaterials field by making implant removal surgery unnecessary, and avoiding the adverse tissue reactions and stres ....Biocompatible magnesium alloys with specific materials properties. This project aims to develop biocompatible magnesium alloys with highly desirable mechanical properties and degradation on demand, and the fundamental science to achieve the materials properties. Injured human bones often need biomaterials to restore function. This project’s magnesium biomaterials could change the biomaterials field by making implant removal surgery unnecessary, and avoiding the adverse tissue reactions and stress shielding typically associated with conventional implanting metals. The outcomes are expected to provide insights in designing biodegradable magnesium alloys and surface coating technology, and generate intellectual properties and advanced biomaterials that will benefit the Australian ageing population.Read moreRead less
The development of lead-free silicon brass for the plumbing industry. The worldwide brass industry is currently undergoing a transition away from lead-containing brass water fittings to lead-free fittings. The transition is driven by concerns surrounding lead-leaching into drinking water. This project is focussed on the development of new lead-free brasses that can be used to manufacture plumbing fittings with superior combinations of processability, performance and cost.
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

This project aims to develop the theory behind why micro alloying contributes to the formation of surface film properties. The exemplar is a prototype Magnesium-Lithium (Mg-Li) base alloy, with high specific-strength and corrosion resistance. This project will lead to the development of a new processable ultra-lightweight, corrosion resistant Mg-Li alloy family that is stronger than the prototype alloy, and with, at least, comparable ductility and corrosion resistance. Not only will the outcomes of the work be a fundamental advance to the fields of metallurgy and corrosion science, they will lead to the identification of an optimised compositional window for creating our second generation Mg-Li alloy family capable of being manufactured into ultra-lightweight, corrosion resistant metal products.Read moreRead less
