Hydrogen embrittlement studies

This electrochemical cell within a tensile load frame was used by Örnek et al. to study the lattice strain evolution during electrochemical hydrogen charging and mechanical loading of a duplex stainless steel. They performed in-situ XRD in order to follow the lattice strain in the austenite and ferrite phases. They also observed differences in the strain partitioning between the two phases.

Experiments were performed at the Swedish Materials Science beamline, P21.2 branch.
