Summary
Enabling a new generation of advanced high-strength aluminium alloys through materials design. This project will create an analysis-engine of novel atom-sensitive methods to unlock the materials science of hierarchy-strengthening. It will assist in determining how hierarchical structures evolve and synergistically strengthen a new generation of advanced high-strength aluminium alloys that are strong as steel, but a third the weight.

Quench and deformation dilatometer for studying phase transformations: The quenching and deformation dilatometer is a high precision thermal analysis tool used to measure phase transformations in situ. This technique can make time-resolved measurements of transformations under the extreme conditions of heating, cooling and deformation that are experienced during industrial processing. This instrument will be the only one in Australia capable of temperature changes above 2000 degrees Celsius and will also be the only one equipped with a cryogenic module. The instrument is intended to be used to characterise new processing technologies and new alloy systems such as advanced high strength steels, age hardenable magnesium, high entropy alloys, and cluster hardening aluminium alloys.Read moreRead less

Summary
Probing the nanomechanics of single grain boundary with decorated solutes. Grain boundaries (GBs) are thermodynamically susceptible to attract solutes to reduce system energy. Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals.

Elaborately manipulating the GB nanostructure and chemistry via segregation can essentially be conducive, rather than detrimental, to materials performance. However, the underlying mechanism of GB segregation and its detailed effect on material properties remain elusive due to the GB complexities in the polycrystals. Through correlative in-situ nanomechanical testing and atom probe tomography, this project aims to unravel the rationale of segregation behaviour of individual GBs and its effectiveness to enhance the material performance, and hence enable nanostructural design of advanced metallic materials with unprecedented properties.Read moreRead less

However, the exact contribution of individual grain boundaries to mechanical properties is not well understood, affecting advanced materials design. This project will use in-situ deformation transmission electron microscopy techniques to reveal how individual grain boundaries deform and interact with dislocations, and to link directly the structures and orientation of individual grain boundaries with mechanical behaviours.

Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will ob ....Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will obtain accurate 3D maps showing the position of hydrogen atoms in steel by combining deuteration with cryogenic atom probe microscopy. In this way we will will elucidate how a proposed solution, hydrogen trapping, reduces hydrogen embrittlement, contributing to design criteria for hydrogen-resistant steels.Read moreRead less
