Exploiting Annealing Reactions for New Steel Grade Development. 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.

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
Effect of Chromium and Manganese on the Formations of Graphite and Carbide on the surface of Low Carbon Sheet Steels. Surface graphite and surface carbide are two surface defects observed in cold-rolled low carbon steel sheets after batch annealing under non-oxidising atmosphere. The surface defects detract from the appearance of the steel sheets and diminish the surface treatment potential of the sheets, causing significant and costly material losses. The aims of the project are to study the in ....Effect of Chromium and Manganese on the Formations of Graphite and Carbide on the surface of Low Carbon Sheet Steels. Surface graphite and surface carbide are two surface defects observed in cold-rolled low carbon steel sheets after batch annealing under non-oxidising atmosphere. The surface defects detract from the appearance of the steel sheets and diminish the surface treatment potential of the sheets, causing significant and costly material losses. The aims of the project are to study the inhibition of surface graphite formation by the additions of Chromium and Manganese and to study the mechanism of formation of surface carbide with the aim of developing an alloying / processing strategy which eliminates both the surface graphite and the surface carbide.Read moreRead less

This project will provide a fundamentally better understanding of the relationship between grain boundary segregation and the recrystallisation behaviour of steel and Al alloys. This knowledge will lead to more efficient thermomechanical processing techniques, which will be of benefit to Australia's steel and light alloy industries. The experimental techniques to be developed will be the first of their kind. They have enormous potential for use in future segregation studies of other alloy systems and are expected to make a major contribution to fundamental and applied research over the next few years.Read moreRead less
The development of optimum microstructures in hot worked metals. Hot working is used to obtain the shape and properties of a wide range of metal products. At present our knowledge of how to control the forming process and properties of the final product is limited to laboratory conditions that do not apply in industry. This work will systematically study the deformation behaviour of a range of metals, including steel, titanium, aluminium, magnesium and copper from standard laboratory to real i ....The development of optimum microstructures in hot worked metals. Hot working is used to obtain the shape and properties of a wide range of metal products. At present our knowledge of how to control the forming process and properties of the final product is limited to laboratory conditions that do not apply in industry. This work will systematically study the deformation behaviour of a range of metals, including steel, titanium, aluminium, magnesium and copper from standard laboratory to real industrial conditions. We will develop advanced models to predict the properties of these metals for any hot working process and identify opportunities to develop new high strength products.Read moreRead less

The aim is to develop iron-based precipitation strengthened shape memory alloys that are capable of recoverable strains > 4% and stresses > 200 MPa, for application as low cost one-way memory devices. Innovative solid solution and precipitation strengthening strategies will be employed to modify dislocation behaviour and stacking fault energy and to improve the reversibility of the martensitic transformation - the key to shape memory behaviour. The interaction of transformation dislocations with strain fields due to coherent particles and solute atoms will be elucidated. Significant increases in shape recovery stress and strain are expected because of increased alloy resistance to irreversible plastic strain.Read moreRead less
