Long-term corrosion of offshore steel structures in near-stagnant seawater. This project investigates the seawater corrosion of structural steels under near-stagnant and possibly polluted conditions. Better understanding of long-term corrosion of structural steels in near-stagnant seawaters is needed to predict the safety of steel offshore structures such as the pods supporting wind and wave energy generators.

This project investigates the seawater corrosion of structural steels under near-stagnant and possibly polluted conditions. Better understanding of long-term corrosion of structural steels in near-stagnant seawaters is needed to predict the safety of steel offshore structures such as the pods supporting wind and wave energy generators. Also, the expensive maintenance of protective coatings and systems could be obviated or reduced if corrosion remains acceptable. This project plans to investigate experimentally the temporal development and stochastic nature of general corrosion and pitting for steels under actual near-stagnant seawater conditions. It also plans to build mathematical-probabilistic models for corrosion prediction, calibrated to field data. These models will include allowance for microbiological corrosion effects, important under anthropological pollution.Read moreRead less
Short- and long-term corrosion of steels in highly calcareous seawaters . This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosio ....Short- and long-term corrosion of steels in highly calcareous seawaters . This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity. It will develop and calibrate corrosion prediction models using classical and recently available 100 year data from Europe, the Pacific, Australia and also new project-specific experimental data. These models are expected to be of benefit for Australian engineering consultants in maintain their internationally competitive edge in offshore engineering.Read moreRead less
Composite Structures of High-Strength Steel and Concrete. This project plans to investigate the use in building frames of composite steel-concrete members that use high-strength steel (HSS) instead of mild steel (MS). HSS is finding increased use in construction, and HSS has a much greater strength-to-weight ratio than MS, leading to lighter composite structures, less material usage and smaller foundations. Overall, this reduces the cost and carbon footprint of steel-framed buildings. The invest ....Composite Structures of High-Strength Steel and Concrete.

HSS is finding increased use in construction, and HSS has a much greater strength-to-weight ratio than MS, leading to lighter composite structures, less material usage and smaller foundations. Overall, this reduces the cost and carbon footprint of steel-framed buildings. The investigation is planned to involve physical testing, numerical studies, developing structural models and crafting design guidance for T-beams, columns and joints. The major intended outcome of the project is design guidance that will support the expanded use of HSS.Read moreRead less

New classes of aluminium-magnesium-silicon alloys via scandium additions. This project aims to establish the knowledge required to be able to improve Aluminium (Al) alloys using scandium (Sc). The transport sector accounts for 20 per cent of all greenhouse gas emissions globally, and the use of Al to reduce the weight of vehicles offers the potential to significantly reduce these emissions, however the properties of current Al alloys do not meet the necessary requirements.

This project aims to establish the knowledge required to be able to improve Aluminium (Al) alloys using scandium (Sc). The transport sector accounts for 20 per cent of all greenhouse gas emissions globally, and the use of Al to reduce the weight of vehicles offers the potential to significantly reduce these emissions, however the properties of current Al alloys do not meet the necessary requirements. To overcome this challenge there is a need for new Al alloys with optimal balance of cost and performance. One opportunity in this area is the use of Sc, however the high Sc price has restricted research thus far. With the recent discovery of rich sources of Sc in Australia, the price of Sc will drop and become a viable solution. This will provide benefits by securing Australia’s position as a leader in the field of advanced Al products for engineering applications.Read moreRead less
