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.

This project aims to develop the theory behind why micro alloying contributes to the formation of surface film properties. The exemplar is a prototype Magnesium-Lithium (Mg-Li) base alloy, with high specific-strength and corrosion resistance. This project will lead to the development of a new processable ultra-lightweight, corrosion resistant Mg-Li alloy family that is stronger than the prototype alloy, and with, at least, comparable ductility and corrosion resistance. Not only will the outcomes of the work be a fundamental advance to the fields of metallurgy and corrosion science, they will lead to the identification of an optimised compositional window for creating our second generation Mg-Li alloy family capable of being manufactured into ultra-lightweight, corrosion resistant metal products.Read moreRead less

The project aims to investigate the complex behaviour of light cold-formed-steel roof and wall systems involving localized failures under the combined action of wind and bushfire using wind suction tests at elevated temperatures combined with advanced numerical modelling. It will generate new knowledge of the behaviour and strength of cold-formed-steel roof and wall systems under bushfire conditions. Expected outcomes include new design models for wind, bushfire and cold-formed-steel Standards. This will significantly improve the bushfire safety of buildings, since non-combustible steel roof and wall systems are used as building envelopes in bushfire prone areas, but are not designed to withstand recently discovered bushfire-enhanced winds.Read moreRead less

This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses.

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
