The work has the potential for very substantial benefit to Australia. Novel stress corrosion cracking resistant tempers with improved strength have the potential for widespread application in the aircraft industry. Since the patent for the interrupted ageing process is held by CSIRO there is the potential for substantial economic benefit to Australia from the licensing of the novel tempers world-wide. Additionally, it would be possible to develop the novel tempers in-situ on existing aircraft structures to improve their performance. This would be of particular benefit to the Royal Australian Airforce with its fleet of ageing aircraft.Read moreRead less
Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, ....Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, agriculture, biomedical, construction, defence, mechatronics, mining, and oil and gas industries, which depend on this materials technology. The benefits will be the creation of leading expertise in advanced manufacturing, support of end-user industries and the establishment of a regional R&D focal point in hard metals.Read moreRead less

Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less
PRODUCTION OF OPTIMAL MICROSTRUCTURED POLYMER OPTICAL FIBRE. Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first.

Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow improved draw reproducibility and fibre uniformity so that commercial quality fibres can be produced at economic rates. We will establish quantitative relationships between drawing parameters and optical properties, thus developing optimal designs and production processes.Read moreRead less
Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres.

This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.Read moreRead less
High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multipl ....High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multiple oxidants within the scale, to establish the mechanisms of oxide scale penetration by foreign species, and to evaluate scales on different alloy types. The results will provide a basis for improved design/selection of heat resisting chromia-forming alloys, key to power generation industries.Read moreRead less
