Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution.

The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.Read moreRead less
Metal folding fundamentals to shape new corrugated building products . FormFlow has developed a ground-breaking forming process enabling the use of corrugated iron as a structural element. This is a step change for Australia`s steel and building industry and will provide a direct benefit to fireproofing homes. Up scaling of this new technology poses significant challenges due to the lack of understanding in the new forming process and the effect of pre-processing on the incoming material.

This is a step change for Australia`s steel and building industry and will provide a direct benefit to fireproofing homes. Up scaling of this new technology poses significant challenges due to the lack of understanding in the new forming process and the effect of pre-processing on the incoming material. Fundamental knowledge of material behaviour will be developed with advanced models that account for the unique process deformation conditions. The intended outcome includes computer software for process design and new concepts for part shape control to improve product quality, repeatability and enable high volume manufacture.Read moreRead less

This project will establish an effective and efficient computational framework for the topological optimisation of composites whose constituent phases possess significantly different Poisson ratios. In particular, the proposed research will be focused on exploiting the dramatic improvements in functional properties of composites when the Poisson ratio of one of the constituent phases is either negative or near its incompressibility limit. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of a new class of composites with exceptional properties. Such new composite systems will have many potential applications, particularly in aerospace, defence and medical industries.Read moreRead less

Solid-state precipitates are key features of the microstructures of many natural and artificial materials and govern their properties. Yet understanding, let alone designing, the microstructures of materials remains a formidable challenge. The recent discovery of a new class of embedded interfaces in aluminium alloys offers the prospect of determining the atomic-scale mechanisms of precipitation. This project aims to apply the latest microscopy and computational techniques synergistically to characterise such interfaces and develop atomic-scale mechanisms of nucleation and growth in model alloy systems. It is expected that this work will constitute a major step towards practical control of solid-state precipitation in technologically important materials.Read moreRead less

Summary
Design of alloys over multiple grain scales for improving fatigue performance. The project will significantly improve the development of engineering alloy design with high fatigue resistance and produce important benefits to Australian manufacturing industries. It will also establish new knowledge and capability in modelling fatigue behaviours, thus producing great benefits to many science and engineering fields.
Flexible roll forming of advanced high strength steel sheet . This project will develop light weight automotive components to assist fuel economy and crash worthiness through flexible roll forming.

This project aims to characterise a new way of generating strengthening precipitate structures for lightweight aluminium alloys. Precipitation in the solid state is key to the performance of many materials, but is especially important for light alloys used in structural applications. This project expects to deliver greater fundamental understanding of precipitation mechanisms and generate experimental and computational methods for three-dimensional characterisation and simulations at the atomic-scale of embedded nanostructures. This should provide significant benefits for the improved design of light alloys, such as for the automotive and aerospace sectors, but also for high-tech materials whose function depends on precipitates.
