RP3.1-02: Atom Probe Tomography for hydrogen interactions with steel pipes

Executive Summary

This project investigates the capability of atom probe tomography for quantifying and understanding hydrogen-steel pipeline interactions through microstructure specific hydrogen mapping. 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 utilising Atom Probe Tomography (APT) is important to improve understanding of the impact of hydrogen on mechanical performance. The objective of this research is to gain better understanding of the interactions between metals in the existing gas pipeline network and hydrogen.

Outcomes / Impact

This project generates knowledge for industry to:

  • ascertain the compatibility or otherwise of current network metallic materials with future fuels, in particular hydrogen for storage and transportation applications; and
  • assist with selection, development and application of new metallic materials capable of storing and transporting a range of new future energy fluids.
