Reactive barriers for the remediation of fluoride contamination in groundwater. This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which h ....Reactive barriers for the remediation of fluoride contamination in groundwater. This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which has shown that calcite can remove 99% of fluoride contamination from water. The project will prove the technology at the field scale and provide the basis for its application to other contaminants.Read moreRead less

Quantitative Atom Probe Tomography for Nanostructural Analysis of Materials. The ultimate in microscopy would involve the ability to image and chemically identify every atom or molecule in a specimen. This project involves the development of reconstruction and analysis methodologies for more accurately determining relative atomic positions in atom probe tomography. We will develop a comprehensive, platform-independent approach to enable quantitative atom probe tomography for the Australian resea ....Quantitative Atom Probe Tomography for Nanostructural Analysis of Materials. The ultimate in microscopy would involve the ability to image and chemically identify every atom or molecule in a specimen. This project involves the development of reconstruction and analysis methodologies for more accurately determining relative atomic positions in atom probe tomography. We will develop a comprehensive, platform-independent approach to enable quantitative atom probe tomography for the Australian research community. This development will be used to address current questions on the influence of the chemistry, crystallography, type and dispersion of sub-critical atomic clusters and supra-critical nanoscale precipitates on the strengthening mechanisms in light alloys used for structural applications in transport.Read moreRead less
Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigate ....Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigated, whereby the fluid mechanics and heat transfer mechanisms within the bath will allow inter-metallic particles to be continuously removed in the metal coating before they reach the critical size that adversely affects product quality. This will also reduce dross accumulation, thereby reducing shutdown time.Read moreRead less

This project aims to develop new understanding of interfacial phenomenon during refractory/metal reactions including the influence of novel additives on wettability leading to optimisation of refractory composition during processing of non-ferrous metals. This project will allow development of advanced refractories that will enhance corrosion resistance thereby improving refractory life and efficiency of metal production. This can contribute in further enhancing Australia's position as a significant producer and exporter of aluminium and associated products. The project will generate scientific data on refractory/metal interactions and establish influence of non-wetting agents in improving refractory performance against metal attack. Read moreRead less
