Hy-APT: Hydrogen visualization at (strained) interfaces in high strength steels by cryo-atom probe tomography
Context
This project addresses one of the challenges related to hydrogen, i.e. its interaction with metals used for storage, transportation or other applications involving hydrogen exposure during their lifecycle. The hydrogen interaction is usually studied by its consequences as direct observation is extremely hard given the size and rate of movement of hydrogen. The SMS group is a member of an innovative multiscale characterization platform in Flanders with cryo-atom probe tomography possibilities (as co-promotor of the FWO Hercules project “Multi-SCOPE”), significant breakthroughs in this area are aimed for as it is key to fundamentally understand the hydrogen interactions with metals at this scale.
Research objectives
The Hy-APT project aims to fundamentally understand hydrogen trapping at two types of interfaces, i.e. cementite and retained austenite, and the role of strain herein. A combined thermal desorption spectroscopy/atom probe tomography approach will lead to new insights. The following research objectives are addressed:
Objective 1 : Clarify the hydrogen trapping ability of cementite
Objective 2: Clarify the trapping ability of retained austenite
