Formatted abstract
The linearly increasing stress test (LIST) was used to study the influence of hydrogen on 3.5NiCrMoV steel in acidified 0.1M Na2SO4, pH 2 at increasingly negative applied potentials to -1700mVAg/AgCl. For specimens tested in solution with an applied potential, there were surface cracks in the necked region, but no surface cracks in the uniformly deformed part of the specimen. This implies that there was no influence of hydrogen up to the yield stress of the steel. Hydrogen induced brittle fracture events made a small contribution to the overall ductile fracture, which occurred after the onset of necking.
