Atom Probe tomography for hydrogen-steel interactions

December 2nd, 2021

R&D Focus Areas:
Pipeline materials and performance, Hydrogen embrittlement

Lead Organisation:
Deakin University

Future Fuels CRC


Start date: September 2019

Project summary description:
The objective of this research is to gain better understanding of the interactions between metals in the existing gas pipeline network and hydrogen. High strength steels are known to be particularly sensitive to hydrogen embrittlement, which manifests as a reduction in mechanical properties and increased susceptibility to failure. Examining where and how the hydrogen interacts with the microstructure using Atom Probe Tomography (APT) is important to improve understanding of the impact of hydrogen on mechanical performance.
