| Abstract Scope |
Hydrogen embrittlement poses a risk for high hardness steel (HHS) and can cause premature failure of the material. An investigation into the susceptibility of HHS to hydrogen embrittlement was performed for selected alloys. Alloys were mechanically evaluated for hydrogen susceptibility by hydrogen charging, zinc electroplating, and slow-strain rate testing of tensile specimens. The results were compared to the performance of the as-received materials. After evaluating the degradation of mechanical properties due to hydrogen embrittlement, the efficacy of hydrogen traps was investigated by conducting hydrogen permeability tests on each material. A comparison was made between the onset of hydrogen embrittlement within the alloy and the diffusivity of hydrogen within the material. |
