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

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
