New classes of aluminium-magnesium-silicon alloys via scandium additions. This project aims to establish the knowledge required to be able to improve Aluminium (Al) alloys using scandium (Sc). The transport sector accounts for 20 per cent of all greenhouse gas emissions globally, and the use of Al to reduce the weight of vehicles offers the potential to significantly reduce these emissions, however the properties of current Al alloys do not meet the necessary requirements.

This project aims to establish the knowledge required to be able to improve Aluminium (Al) alloys using scandium (Sc). The transport sector accounts for 20 per cent of all greenhouse gas emissions globally, and the use of Al to reduce the weight of vehicles offers the potential to significantly reduce these emissions, however the properties of current Al alloys do not meet the necessary requirements. To overcome this challenge there is a need for new Al alloys with optimal balance of cost and performance. One opportunity in this area is the use of Sc, however the high Sc price has restricted research thus far. With the recent discovery of rich sources of Sc in Australia, the price of Sc will drop and become a viable solution. This will provide benefits by securing Australia’s position as a leader in the field of advanced Al products for engineering applications.Read moreRead less

The phase transformation thermodynamics of post-transition metals, which form low-melting-point alloys, remain largely unknown. This project aims to explore low-energy metallurgy pathways enabled by liquid metals to discover such dynamics. The strategy is to harvest structured/crystalline materials by incorporating target metal species into liquid metal solvents and stimulating autonomous phase separation and pattern formation during phase transition. Contemporary instruments and technologies will be employed to achieve active control of these fundamental processes at different scales. The expected outcomes will reveal new insights in traditional metallurgy as well as extend metallurgical concepts to electronics, optics, and catalysis.Read moreRead less

This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices. Read moreRead less
