Hydrogen embrittlement in steels is a major impediment to a safe hydrogen economy. This project will determine how hydrogen affects the deformation behaviour of steel, providing the fundamental information that is required to develop alloys that can be safely used in infrastructure for a future Australian hydrogen industry. We will utilise new technologies that allow us, for the first time, to determine the position of hydrogen atoms around micro-scale features and to compare it to local mechanical behaviour, determined by micro-mechanical tests. The systematic investigation of the effect of hydrogen on different micro-components within steel will allow the development of microstructure-guided alloy design principles.Read moreRead less

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
