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
Hybrid Toughening of Carbon Fibre Composites for Liquid Hydrogen Storage. This project aims to develop hybrid toughening technologies to overcome the major problem of transverse matrix cracking and splitting in existing carbon fibre composites when subjected to thermal-mechanical loading at the ultracold liquid hydrogen temperature. Nano-toughened thin-ply carbon fibre layers will be hybridised with standard-ply laminates to sustain internal pressure and external impact loading at cryogenic temp ....Hybrid Toughening of Carbon Fibre Composites for Liquid Hydrogen Storage. This project aims to develop hybrid toughening technologies to overcome the major problem of transverse matrix cracking and splitting in existing carbon fibre composites when subjected to thermal-mechanical loading at the ultracold liquid hydrogen temperature. Nano-toughened thin-ply carbon fibre layers will be hybridised with standard-ply laminates to sustain internal pressure and external impact loading at cryogenic temperatures without leaks. The hybrid composites are expected to enable Australian companies to engineer, manufacture and export lightweight carbon fibre tanks for storing and exporting liquid hydrogen, which is emerging as a transformational opportunity for Australia to become a global supplier of green energy.Read moreRead less

Summary
In-situ nanomechanical testing for materials under extreme environments. This project aims to establish a state-of-the-art in-situ nanomechanical testing capability for materials under extreme environments. A cutting-edge nanoindentation stage with customisable modules, as well as an optimally configured scanning electron microscope, will enable this capability for the first time in Australia.

This project aims to establish a state-of-the-art in-situ nanomechanical testing capability for materials under extreme environments. A cutting-edge nanoindentation stage with customisable modules, as well as an optimally configured scanning electron microscope, will enable this capability for the first time in Australia. The expected outcomes will provide valuable insights into how microstructures affect mechanical properties at temperatures ranging from -150 to 1000 °C, strain rates from 10E-5/s to 10E5/s, and liquid environments. The resulting knowledge will guide the development of structural materials that withstand harsh environmental conditions, thereby advancing Australia's advanced manufacturing and sustainable energy sectors.Read moreRead less
