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

Studies in solid-gas reactions : precipitate formation and dissolution; carbide production and metal dusting. Reducing carbonaceous gases which become supersaturated with carbon can react with both oxides and metals. They reduce iron oxide and, if methane is used, produce iron carbide, a valuable material. However, they react with iron and alloy steels to destroy them, producing a dust of carbon, metal and metal carbides, a process in which iron carbide is thought to form only as a relatively ....Studies in solid-gas reactions : precipitate formation and dissolution; carbide production and metal dusting. Reducing carbonaceous gases which become supersaturated with carbon can react with both oxides and metals. They reduce iron oxide and, if methane is used, produce iron carbide, a valuable material. However, they react with iron and alloy steels to destroy them, producing a dust of carbon, metal and metal carbides, a process in which iron carbide is thought to form only as a relatively short-lived transient species. This program will study both reactions and determine the processes whereby new phases nucleate and grow or disintegrate.Read moreRead less
Anisotropy of strengthening by solid solution and precipitation in concentrated Mg-Al and Mg-Zn alloys. The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys.

The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys. Easier prismatic slip lowers the strain hardening rate and increases the ductility of polycrystalline alloys in comparison with pure Mg. Despite their obvious significance, these effects have not been studied in single crystals of concentrated alloys. This is the main object of this project.Read moreRead less

The work has the potential for very substantial benefit to Australia. Novel stress corrosion cracking resistant tempers with improved strength have the potential for widespread application in the aircraft industry. Since the patent for the interrupted ageing process is held by CSIRO there is the potential for substantial economic benefit to Australia from the licensing of the novel tempers world-wide. Additionally, it would be possible to develop the novel tempers in-situ on existing aircraft structures to improve their performance. This would be of particular benefit to the Royal Australian Airforce with its fleet of ageing aircraft.Read moreRead less
