The project has both national and international significance and addresses the National Research Priority: Frontier Technologies - Advanced Materials (light alloys). Rapid manufacturing produces functional parts directly from a computer solid model using a layer wise rapid prototyping device. Rapid manufacturing is particularly important in the Australian context where small production runs means that tooling and inventory costs are a much larger proportion of the total cost than in North American, European or Asian countries. With a large installed machine base, a substantial automotive and automotive component industry and a major aluminium industry, this project can assist in the further development of these industries.Read moreRead less

On demand three-dimensional printing of stainless steel parts. This project aims to revolutionize the security of supply of critical stainless steel parts by producing them on-site and on demand, using three dimensional metal printing. Australia’s oil and gas industry uses tonnes of stainless steel for critical processing components in production plants. Australia is also one of the few developed nations without appreciable production and processing facilities for stainless steels, so relies on specialist overseas suppliers. This is a major risk to the industry, which stores billions of dollars’ worth of replacement parts, including stainless steels, in inventory. This project should reduce reliance on overseas steel suppliers and free up hundreds of millions of dollars of capital invested in the inventory stores of replacement stainless steel parts.Read moreRead less
Design and fabrication of custom titanium implant scaffolds produced by selective laser melting. The development of implants that can be tailored to match individual patient requirements will result in increased functionality and longevity of the device, decreased pain and suffering and a reduction in hospitalisation time and medical costs.

The development of implants that can be tailored to match individual patient requirements will result in increased functionality and longevity of the device, decreased pain and suffering and a reduction in hospitalisation time and medical costs. This is especially true where massive bone loss has occurred. Research in this area is vital to underpin Australian technological progress in a field of rising economic and social importance, especially given Australia's aging population. The project will strengthen expertise in materials science and mathematical optimization. Further, the coupling of these fields will allow Australian scientists and technologists to exploit the full potential of solid freeform fabrication in new applications.Read moreRead less

Exceptional properties by design – NiTi vision. The fundamental leaps in new technologies occur with improvements in the materials with which they are made. Until recently high performance metallic composite design had hit a 20 year blockage in nanocomposite design. The solution, a Nickel, Titanium and Niobium (NiTi-Nb) nanowire composite has been heralded as an era of new possibilities in materials design.

The fundamental leaps in new technologies occur with improvements in the materials with which they are made. Until recently high performance metallic composite design had hit a 20 year blockage in nanocomposite design. The solution, a Nickel, Titanium and Niobium (NiTi-Nb) nanowire composite has been heralded as an era of new possibilities in materials design. This project aims to advance high performance metallic composite design by investigating the mechanisms of exceptionally large elastic strains achieved in nanowires embedded in a phase-transforming metallic matrix (i.e. NiTi). An understanding of this high performance nanocomposite design has broad application in medicine and engineering.Read moreRead less
Approaching near-ideal strength for bulk amorphous metals. This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within.

This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable collective atomic load transfer to allow the amorphous matrix to continue to load to achieve its intrinsic near-ideal strength. The amorphous matrix eliminates the grain boundary plasticity of the nanoscrystallites. This concept is novel and untested in the history of physical metallurgy.Read moreRead less
