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

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.

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

For Australia to maintain its position as a world leader in the science of metals processing it must have the capability for state-of-the-art physical simulation. The present proposal is for the purchase and installation of two leading edge simulation tools: a high rate/short inter-pass hot deformation simulator and a hot equal channel angular extrusion press. Advanced hot deformation simulation is required for the development and optimisation of "fast" industrial processes and for understanding the complex microstructural reactions associated with them. High temperature extrusion is required for the development of ultra-fine and nano-grained light metals.Read moreRead less
Development of ultrafine Grained Steels. This project will develop new methods to produce steels with much finer microstructures, and investigate how these microstructures form. This will markedly increase the strength and toughness of these steels, which is particularly required for the pipeline, off shore platform and large construction industries. The method to be used involves controlling the hot deformation of the steel and control of the phase transformation during or after deformation. ....Development of ultrafine Grained Steels.

The desire to reduce the weight of automobiles due to legislative requirements on fuel emissions and to reduce overall fuel consumption is the driving force behind research into the development of new Mg-based alloys to replace the heavier steel and Al-alloy components in automobiles. Given the enormous worldwide transportation market and the environmental and legislative motivation for reducing fuel emissions, the development of new Mg-based alloys capable of meeting this demand from automotive manufacturers represents both a potentially large economic advantage to the country of development as well as helping to address the environmental concern about fuel emissions.Read moreRead less
