Atomistic mechanisms of the mechanical behaviour of nanostructured silicon carbide films. Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications.

Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications. This project aims to understand the mechanisms behind the exceptional properties in ns SiC and to explore the possibility of realizing the two properties in the same ns SiC. The results obtained from this research will be very important for guiding the structural design of SiC with exceptional mechanical properties which will have a wide range of structural applications.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

Spin Electronics technology will enable a revolutionary class of electronic devices. Gallium nitride (GaN) containing transition metals (TM) (eg Mn, Ni and Fe) is a very promising dilute magnetic semiconductor for practical spintronics applications as this material exhibits magnetic behaviour above room temperature. However, electronic and magnetic properties of this new class of semiconductors have not yet been optimised.

This project seeks to develop a new class of electron field emitting nanocomposite consisting of nanotubes in liquid crystalline polymers. Electron emitting materials are in much demand in x-ray and microwave generation, computer displays and low-energy lighting. We utilise the ready alignability of liquid crystalline units in magnetic fields to cause realignment of incorporated carbon nanotubes, followed by polymer solidification to maintain orientation. It involves low temperature processing, contrasting very favourably with current problematic, high temperature processes. This allows materials to be cast on flexible polymer substrates, potentially enabling construction of cathode tubes to replace existing mercury-containing fluorescent lighting.Read moreRead less
