Technological advances bring demands for new engineering materials and the improvement of existing ones. Since almost every property of such materials depends directly or indirectly on matter transport, it is imperative that the materials designer can accurately predict its direction and extent. This theoretical project, supported and tested by computer simulation, will provide this knowledge. It will develop a toolbox of robust and versatile expressions for predicting and interpreting matter transport in alloy systems at high temperatures. With these expressions in hand, the designer will be in a superior position to tailor the properties of such materials.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
A Predictive Theory of Kinetic Demixing in Engineering Ceramics. Technological advances bring demands for new engineering ceramics and the improvement of existing ones. The properties of engineering ceramics are critically dependent on the composition and distribution of atomic components. However, separation or demixing of the components occurs in-service at high temperatures as a result of stress, electric fields or oxygen gradients. Demixing causes a major loss of performance and longevity. T ....A Predictive Theory of Kinetic Demixing in Engineering Ceramics.

The properties of engineering ceramics are critically dependent on the composition and distribution of atomic components. However, separation or demixing of the components occurs in-service at high temperatures as a result of stress, electric fields or oxygen gradients. Demixing causes a major loss of performance and longevity. This Project will develop a robust and versatile theory of demixing to enhance longevities of engineering ceramics. It will also guide the deliberate manipulation of demixing to generate novel compositionally-graded engineering ceramics having new properties of technological interest.Read moreRead less
