Project summary description:
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 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.
