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

Summary
A novel fundamental approach to enable net shape manufacturing of low-cost high-performance titanium alloys . Oxygen is the bottleneck issue of titanium powder metallurgy, which radically deteriorates the ductility of titanium. This project aims to develop the essential fundamental knowledge and technical solutions to mitigate the detrimental effect of oxygen on the ductility of as-sintered titanium products and enable the net-shape fabrication of low-cost high-performance titanium alloys. This ....A novel fundamental approach to enable net shape manufacturing of low-cost high-performance titanium alloys . Oxygen is the bottleneck issue of titanium powder metallurgy, which radically deteriorates the ductility of titanium. This project aims to develop the essential fundamental knowledge and technical solutions to mitigate the detrimental effect of oxygen on the ductility of as-sintered titanium products and enable the net-shape fabrication of low-cost high-performance titanium alloys. This will be achieved by utilising the inexpensive and unique titanium hydride powder, rather than titanium metal powder, and by developing effective oxygen scavengers. The outcomes will form a robust basis for the creation of a viable titanium hydride powder metallurgy business.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. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable ....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. 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

The development of lead-free silicon brass for the plumbing industry. The worldwide brass industry is currently undergoing a transition away from lead-containing brass water fittings to lead-free fittings. The transition is driven by concerns surrounding lead-leaching into drinking water. This project is focussed on the development of new lead-free brasses that can be used to manufacture plumbing fittings with superior combinations of processability, performance and cost.
New Wrought Magnesium Alloys: Manipulating the Annealed Microstructure. One of the main impediments to increased use of wrought magnesium is its characteristic but mediocre mechanical properties. The proposed work paves the way for new improved wrought magnesium alloys by determining how the constituent nano-structures, micro-structures and deformation conditions can be manipulated to control the evolution of properties during annealing. The project will deliver mathematical models describing th ....New Wrought Magnesium Alloys: Manipulating the Annealed Microstructure. One of the main impediments to increased use of wrought magnesium is its characteristic but mediocre mechanical properties. The proposed work paves the way for new improved wrought magnesium alloys by determining how the constituent nano-structures, micro-structures and deformation conditions can be manipulated to control the evolution of properties during annealing. The project will deliver mathematical models describing the annealed microstructure and mechanical properties. The work will also explore the potential of a recent discovery made by the CI of a simple technique to randomise the alignment of the annealed atomic lattice structure, which promises to markedly improve formability.Read moreRead less
Modelling twinning transitions in light metals: a new foundation for alloy and process development. Australia's quest to become a world leader in light metals technology is being held back by a lack of quantitative understanding of the metallurgical behaviour of magnesium, which is the lightest engineering metal, and titanium, which is the strongest light metal. In particular, there is poor knowledge of the influence of material parameters on deformation twinning.

Australia's quest to become a world leader in light metals technology is being held back by a lack of quantitative understanding of the metallurgical behaviour of magnesium, which is the lightest engineering metal, and titanium, which is the strongest light metal. In particular, there is poor knowledge of the influence of material parameters on deformation twinning. This knowledge is vital for efficient production and optimised alloy and part design. This proposal aims to develop a quantitative understanding of transitions in twinning activation for improved performance in fatigue, crash behaviour, structural integrity, forming, forging, extruding, hot rolling and annealing.Read moreRead less
