Effects of Electrochemical Hydrogen Charging Parameters on the Mechanical Behaviors of High-Strength Steel [PDF]
MaterialsExtended exposure to seawater results in the erosion of the structural high-strength steels utilized in marine equipment, primarily due to the infiltration of hydrogen. Consequently, this erosion leads to a decrease in the mechanical properties of the material.

Electrochemical hydrogen charging to simulate hydrogen flaking in pressure vessel steels [PDF]
Engineering Fracture Mechanics, 2019 The current study investigates hydrogen flaking in large forgings. Two industrially forged pressure vessel materials, exhibiting different segregation behavior are compared for this purpose. Electrochemical hydrogen charging is used to simulate the flakes, present in real-life applications, on a small scale. As such, the sensitivity of the materials to

Effect of electrochemical charging on the hydrogen embrittlement susceptibility of alloy 718 [PDF]
Acta Materialia, 2019 Abstract The susceptibility of age-hardened nickel-based Alloy 718 to hydrogen embrittlement was studied by the controlled electrochemical charging combined with slow strain-rate tensile tests (SSRT) and advanced characterization techniques. We proposed some novel ideas of explaining hydrogen embrittlement mechanisms of the studied material in regard

Electrochemical Hydrogen Charging of Duplex Stainless Steel [PDF]
Corrosion, 2018 This study evaluates the electrochemical hydrogen charging behavior and interaction between hydrogen and the microstructure of a duplex stainless steel. A saturation level of approximately 650 wppm is reached after 10 d of charging. The data are compared with a model resulting in a diffusion coefficient of 2.1 × 10−14 m2/s.

Assessment of the potential of hydrogen plasma charging as compared to conventional electrochemical hydrogen charging on dual phase steel [PDF]
Materials Science and Engineering: A, 2019 Abstract The present study evaluates the hydrogen induced damage by in-situ hydrogen plasma charging in dual phase (DP) steel. Cold deformation of 15% is applied on the material to change microstructural defects, such as dislocation density. The susceptibility to hydrogen embrittlement is hence evaluated for two material conditions, i.e. DP 0% and DP

Determination of the equivalent hydrogen fugacity during electrochemical charging of 3.5NiCrMoV steel [PDF]
Corrosion Science, 2018 A new thermal desorption spectroscopy (TDS) apparatus was used to identify the hydrogen trapping peaks, and to measure the hydrogen concentrations in 3.5NiCrMoV steel after hydrogen charging electrochemically, and in gaseous hydrogen. The hydrogen concentration increased with (i) increasingly negative charging potential and (ii) increasing hydrogen gas
