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. We plan to exploit the technique to mediate a step change in modelling strength based on ....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. 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 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.
