The proposed project aims to develop a sound understanding of the mechanism and rate of condensation of zinc vapour on clean and partially oxidised steel strip surfaces. This Fundamental scientific knowledge is the key to furthering our understanding of the effect of process variables on the occurrence of pinholes and bare patches on ZINCALUME coated steel strip. Should the fundamental causes of defect formation be established, product quality can be improved, process costs reduced and the Australian industry's competitive position in the market place retained. A new experimental approach will be taken; conductive to the training of the researchers involved in advanced research techniques.Read moreRead less

This proposal involves the application of three dimensional atom probe field ion microscopy and advanced transmission electron microscopy techniques to study the phenomena of precipitation and solute atoms' interactions with dislocations in warm rolled low carbon steels and interstitial free steels. It is intended to examine the effect of alloying additions on in-grain shear bands formation, texture formation and formability of warm rolled and annealed low carbon steels. Ultimately, the project is concerned with developing of fundamental understanging of solute interactions which provide an improved basis for design of these economically significant steels.Read moreRead less

Summary
Near Net Shaped Casting and Alloy Development Facility. Nearly all metal production is based around an initial casting phase, often followed by other deformation and thermal processes. This facility will allow us to study current and future advanced alloys and processing routes, including metals of strategic importance to Australia such as aluminium, titanium and magnesium. One of the major innovations for these metals is to directly cast to strip, followed by minimal processing to provide str ....Near Net Shaped Casting and Alloy Development Facility. Nearly all metal production is based around an initial casting phase, often followed by other deformation and thermal processes. This facility will allow us to study current and future advanced alloys and processing routes, including metals of strategic importance to Australia such as aluminium, titanium and magnesium. One of the major innovations for these metals is to directly cast to strip, followed by minimal processing to provide strip products with novel properties, low capital costs and short lead times. The outcomes from this research will support the development of existing and new metal industries in Australia.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

An exciting class of materials has emerged with grain sizes two orders of magnitude finer than that produced by conventional processing. These nanocrystalline alloys are produced by intense plastic straining termed equal channel angular extrusion (ECAE). The aim of the project is to incorporate novel experimental techniques, using single crystals, in situ annealing and 3-D computer simulation to develop a fundamental understanding of microstructural stability during ECAE and subsequent thermal treatment. Such advances in our understanding of boundary mobility in fine-scale microstructures is important for evaluating their stability and, hence, the possible commercial exploitation of these materials.Read moreRead less
