Titanium Alloy Scaffolds for Osseointegration Implant Materials. Australians' life expectancies are among the highest in the world. Degeneration of load bearing bones in the elderly of age 65 and over often requires the inception of biomaterial implants. For the hip and knee replacements alone, there are over 52,000 operations performed in Australia each year at an estimated cost of over $500 million. The success of these procedures depends on the implant biomaterials. The outcomes of this proje ....Titanium Alloy Scaffolds for Osseointegration Implant Materials.

These novel materials, with tailored porosity and surface functionality, will decrease both radioactive waste volume and the potential for environmental risk. The collaboration between the Caruso group at the University of Melbourne and the Luca group at ANSTO will educate more scientists and students in the areas of nuclear science and engineering, and the environmental impact of nuclear power generators. Such expertise is currently in high demand around the world, thereby enhancing Australia's position in the global nuclear field.Read moreRead less
Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly. To develop the process it will be necessary to understand the mechanism of dirt adhesion to paints and the modes of operation of current dirt resistant processes. In addition work will be ....Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly. To develop the process it will be necessary to understand the mechanism of dirt adhesion to paints and the modes of operation of current dirt resistant processes. In addition work will be required on the rate of surface segregation of additives to the paint solution. We propose to combine experimental and theoretical modelling approaches to obtain a fundamentally sound practical solution.Read moreRead less
The development of optimum microstructures in hot worked metals. Hot working is used to obtain the shape and properties of a wide range of metal products. At present our knowledge of how to control the forming process and properties of the final product is limited to laboratory conditions that do not apply in industry.

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.
