Abstract Scope |
High hardness steels (HHS) are vulnerable to hydrogen embrittlement, which can lead to rapid degradation of mechanical properties. A comparison study was performed to assess the hydrogen susceptibility of select commercially available HHS alloys. Slow-strain rate tensile tests, performed with specimens charged with various levels of hydrogen, provided a macroscopic view of the onset of hydrogen embrittlement. Hydrogen permeation testing of the HHS alloys determined the uptake and diffusivity of hydrogen through the material. Quantification of hydrogen trapping sites within the HHS alloys was performed using electron microscopy. The evaluation of current HHS alloys’ susceptibility to hydrogen serves as a baseline for future hydrogen embrittlement mitigation strategies. |
