Metal injection moulding of aluminium. The aim of this project is to develop a metal injection moulding (MIM) system for aluminium by employing point defect engineering to enhance the solid state sintering of aluminium. This study will also incorporate an econometric analysis of the potential for specific aluminium MIM parts. Using this novel, multidisciplinary approach, the market definition and the technology development will occur concurrently. The outcome will be an aluminium MIM system and ....Metal injection moulding of aluminium.

This study will also incorporate an econometric analysis of the potential for specific aluminium MIM parts. Using this novel, multidisciplinary approach, the market definition and the technology development will occur concurrently. The outcome will be an aluminium MIM system and a new business opportunity for a Queensland manufacturing company in a market that is growing at 10-25% per year and is expected to exceed $US1 billion in 2003.Read moreRead less
Zirconium alloying and grain refinement of magnesium alloys with ZirCAST. Zirconium alloying and grain refinement is a key issue restricting the commercial production of value-added zirconium-containing magnesium alloys for use in the automotive industry. This 3-year linkage program builds on the applicants' invention of a proprietary grain refiner ZirCAST, and is undertaken to investigate the major fundamental aspects of zirconium alloying and grain refinement with ZirCAST. In addition to an ex ....Zirconium alloying and grain refinement of magnesium alloys with ZirCAST. Zirconium alloying and grain refinement is a key issue restricting the commercial production of value-added zirconium-containing magnesium alloys for use in the automotive industry. This 3-year linkage program builds on the applicants' invention of a proprietary grain refiner ZirCAST, and is undertaken to investigate the major fundamental aspects of zirconium alloying and grain refinement with ZirCAST. In addition to an excellent postgraduate training environment, it aims to provide and develop, in partnership with industry, optimum zirconium alloying and grain refinement technology with ZirCAST and enhance Australia's leading global position in this strategically and commercially important area.Read moreRead less
Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous ....Fundamental understanding of the environmental factors essential for environmental assisted fracture (EAF) of cast magnesium alloys. This project proposes a combined theoretical and experimental approach to understand the key environmental factors causing EAF of commercial cast magnesium alloys. Rather than testing all possibilities, it is proposed to establish a mechanistic understanding for EAF, and to test and expand that understanding through key experiments. EAF is a particularly dangerous and complicated form of corrosion. Existing experience indicates that EAF incidence will increase as magnesium alloys are increasingly used in more challenging applications. The results and insights from this research will help to underpin a major new industry and industrial applications.Read moreRead less
Precision Bending of 6xxx Aluminium Extrusions. The use of aluminium in transportation applications is predicted to double over the next 10 years. The use of extruded aluminium in structural components such as space frames is a growing area, and bending is an integral and critical process in the production of such components. The aim of this project is to develop key knowledge and technology necessary for precision bending of extruded aluminium profiles. The main outcomes will be: (i) Understand ....Precision Bending of 6xxx Aluminium Extrusions. The use of aluminium in transportation applications is predicted to double over the next 10 years. The use of extruded aluminium in structural components such as space frames is a growing area, and bending is an integral and critical process in the production of such components. The aim of this project is to develop key knowledge and technology necessary for precision bending of extruded aluminium profiles. The main outcomes will be: (i) Understanding of the relationship between extrusion conditions, microstructure and bendability of structural profiles. This will enable the optimisation of the extrusion process to ensure consistent bending behaviour. (ii) Development of the rubber-pad technology for precision bending.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
