A comprehensive theoretical and simulation model for control of nucleation, prediction of as-cast grain size, and design of grain refining technology. The research will generate know-how and methods for predicting the as-cast microstructure of all metallic alloys. The outcomes enable the design of commercially viable grain refining technologies, and the development of novel microstructures that will improve the properties and quality of new products and contribute to waste and energy reduction.

A New Approach to Advanced Steels via Cluster and Precipitate Strengthening. Formation of interphase nanoparticles and clusters is a new approach to increase strength in advanced high strength steels. Exceptionally high strength levels can be achieved in alloys that only have solute clusters by controlling the temperature-time history. However, the exact mechanism for the formation of clusters and precipitates and the cluster strengthening mechanism are not understood, nor do we know how to cont ....A New Approach to Advanced Steels via Cluster and Precipitate Strengthening. Formation of interphase nanoparticles and clusters is a new approach to increase strength in advanced high strength steels. Exceptionally high strength levels can be achieved in alloys that only have solute clusters by controlling the temperature-time history. However, the exact mechanism for the formation of clusters and precipitates and the cluster strengthening mechanism are not understood, nor do we know how to control cluster formation. This project aims to develop a fundamental understanding of the formation of clusters and nanoprecipitates and determine their contribution to strengthening and other mechanical properties using advanced characterisation techniques such as atom probe tomography and electron microscopy.Read moreRead less
Advanced high strength steels produced by energy efficient direct strip casting. Over one billion tonnes of steel is produced every year and one method of reducing the environmental footprint of this production is through strip casting. This process reduces the energy required to process liquid steel into thin sheet product by an astounding 90 per cent. This proposal aims to expand the application of this technology to new steel grades.
Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high ....Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high temperatures. Traditional steels are inadequate. Instead, nickel-base alloys are needed. This project aims to investigate the corrosion behaviour of nickel base alloys in carbon dioxide - water atmospheres, and ways of preventing this corrosion by controlling gas composition and appropriate alloying, which is essential for next generation power plant design.Read moreRead less
Role of oxide grain boundaries in controlling high temperature corrosion of steels by carbon dioxide-rich gases. Advanced coal combustion technologies make carbon dioxide capture possible, but require improved materials to handle hot carbon dioxide-rich gases. These gases are surprisingly corrosive and the corrosion process is not fully understood. This project aims to achieve this understanding and to provide the basis for future alloy design.
Theoretical model that predicts the grain size of alloys inoculated with micro- and nano- particle master alloys and cast under an external field. The aim of this project is to develop a theoretical model that predicts grain size when components are cast under the influence of external fields (electromagnetic, ultrasonic, pulsed electric current and melt shearing treatments) and with the addition of nano-particle master alloys. Refining microstructures by available master alloys is reaching a li ....Theoretical model that predicts the grain size of alloys inoculated with micro- and nano- particle master alloys and cast under an external field. The aim of this project is to develop a theoretical model that predicts grain size when components are cast under the influence of external fields (electromagnetic, ultrasonic, pulsed electric current and melt shearing treatments) and with the addition of nano-particle master alloys. Refining microstructures by available master alloys is reaching a limit and this limits further improvement in mechanical properties to meet the challenge of new applications requiring, for example, high temperature properties or light weighting (for example, use of less material). The outcomes will be a new theoretical model, validated numerical models, new casting technologies and highly refined alloys with greater than 25 per cent improvement in mechanical properties.

Novel energy-efficient electrowinning anodes. Developed nations rely extensively on metallic materials to sustain modern society. This places a significant importance on delivery of base metals, and that delivery must be as efficient and clean as possible. The first step in the delivery chain is extraction from the ore, and much of this technology is based on electrowinning (EW), where the behaviour of the anode is critical to overall process efficiency. This project will deliver advances in EW ....Novel energy-efficient electrowinning anodes. Developed nations rely extensively on metallic materials to sustain modern society.

The first step in the delivery chain is extraction from the ore, and much of this technology is based on electrowinning (EW), where the behaviour of the anode is critical to overall process efficiency. This project will deliver advances in EW anodes which will lead to energy savings, which in turn, will result in a cleaner overall production cycle, major emission reductions and cost savings. The expected outcomes of this project are targeted at the development of new and advanced anode materials.Read moreRead less
