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.
Exploiting Annealing Reactions for New Steel Grade Development. Overseas steel markets are demanding thinner and cheaper formable products.

Overseas steel markets are demanding thinner and cheaper formable products. The proposed work aims to establish how the reactions that take place during annealing can be exploited to create new products to meet these needs. The processes of recrystallization texture development, which controls the ease with which the product can be drawn into shapes, precipitate dissolution, which impacts on surface quality, and creep, which can lead to annealing defects in thin products will be studied. The objective is use the knowledge generated to remove over-design of processing parameters and steel composition to develop new cost effective export grades.Read moreRead less
Nanostructured magnetic materials for clean automotive technologies. Greater utilisation of the petrol-electric hybrid technology is an effective and realistic approach to the problem of increasing greenhouse gas emissions from transportation sources. Owing to the requirement of the temperature stability of the magnets used in the electric motors in the current hybrid vehicles, the magnets contain considerable amounts of costly rare-earth elements. This impedes the utilisation of the technology ....Nanostructured magnetic materials for clean automotive technologies. Greater utilisation of the petrol-electric hybrid technology is an effective and realistic approach to the problem of increasing greenhouse gas emissions from transportation sources. Owing to the requirement of the temperature stability of the magnets used in the electric motors in the current hybrid vehicles, the magnets contain considerable amounts of costly rare-earth elements. This impedes the utilisation of the technology and hence alternative cost effective magnets with high temperature stability are needed. In this project we will exploit a range of alloy design strategies in manganese-bismuth/iron nanocomposite magnets, thereby realising a novel permanent magnet, free of costly rare-earth elements.Read moreRead less

Direct strip casting is an emerging green technology that reduces the energy required to process liquid steel into thin sheet product by up to 90 per cent. This study plans to use advanced atomic-scale characterisation techniques such as atom probe tomography and high-resolution electron microscopy to understand the non-equilibrium microstructures that develop as a result of the extremely rapid cooling rates experienced during strip casting.Read moreRead less

This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.Read moreRead less
Nanostructured soft magnetic alloys for low-carbon cars. The aim of this project is to prepare iron-based magnetic nanostructures that exhibit a magnetic induction of 1.9 tesla and core losses lower than those of iron-silicon steels, which would deliver smaller and efficient magnetic cores for petrol-electric hybrid cars. Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of ....Nanostructured soft magnetic alloys for low-carbon cars.

Preliminary results from the research team show that iron-metalloid alloys with an iron content of 87 per cent meet this magnetic induction with room for further improvement of magnetic softness. The project aims to systematically investigate the effect of metalloid and micro-alloying elements on the nano-crystallisation behaviour of the precursor amorphous alloys in order to identify the alloy composition and processing conditions for preparing magnetically soft nanostructures.Read moreRead less
