Hydrogen Can Cause Brittleness in Several Metals

Caption

Hydrogen can cause brittleness in several metals including ferritic steel, but recent advancements provide insight into the embrittlement process. a) The arrowhead-shaped delaminations in stainless steel reveal cracks with significantly higher deuterium concentrations b) Secondary ion cross-sectional profile for one such delamination.
