“…There is a general agreement as to the effect of cold working on hydrogen permeation. Plastic straining increases the number of dislocations that act as hydrogen traps, increasing hydrogen solubility and resulting in a consequent decrease in D eff (Bockris, Beck, Genshaw, Subramanyan, & Williams, 1971;Bockris, McBreen, & Nanis, 1965;Choo & Lee, 1983;Dietzel, Pfuff, & Juiffs, 2006;Fallahmohammadi et al, 2014a,b;Ha, Ai, & Scully, 2014;Hirth, 1980;Hudson & Straagand, 1960;Kumnick, 1980;Olden, Senumstad Hauge, & Magne Akselsen, 2012;Oriani, 1970;Radhakrishnan & Shreir, 1967;Xie & Hirth, 1982).…”

This article deals with the risk of environmentally assisted cracking of steel structures that are kept under cathodic protection (CP). The experimental results collected on both hydrogen diffusion and hydrogen embrittlement (HE) of high-strength low-alloy (HSLA) steels under CP are discussed. Hydrogen diffusion was evaluated by permeation experiments and a scanning photoelectrochemical current technique, as a function of microstructure orientation, on both loaded and unloaded specimens. HE tests were carried out under constant load, slow strain rate (SSR tests), and slow bending conditions. Tests were also carried out on several grades of HSLA steel having different microstructures. The results confirm that HE in artificial seawater under CP can occur in steel with tensile yield strength in the range of 400–660 MPa only in the presence of high cathodic polarization and continuous plastically straining conditions. HE susceptibility increased with increasing applied cathodic polarization and with decreasing strain rate. HE susceptibility of the rolled steels at relatively high strain rate (10-4 to 10-5 s-1) increased with the hydrogen diffusion coefficient. Similar results were observed in terms of the HE contribution to corrosion fatigue crack growth rate. High-temperature-tempered martensitic steels showed a lower HE susceptibility.

“…Additionally, the as-quenched martensite contains the lowest hydrogen diffusivity due to the dense microstructure. [19][20][21] On the contrary, tempered bainite or martensite has the best resistance against the hydrogen-induced ductility loss, while the pearlitic structure performs in between. 22 In another study on the hydrogen diffusivity of different microstructural features, Chan and Charles 23 found that martensite demonstrated the highest hydrogen solubility together with the lowest hydrogen diffusivity.…”

The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The hydrogen embrittlement susceptibility is evaluated by mechanical tests on both in situ hydrogen pre-charged and uncharged specimens. The observed ductility loss of the materials is correlated with the present amount of hydrogen and the hydrogen diffusion coefficient. In addition to the correlation between the amount of hydrogen and the hydrogen-induced ductility loss, the hydrogen diffusion during the tensile test, quantified by the hydrogen diffusion distance during the test, appears to be of major importance as well.

“…The main ones are temperature, alloy composition, crystalline structure and substructure. Nevertheless, the presence of H in metals and specifically in steels is not desired in most of the cases, since H alters considerably the mechanical-metallurgic properties of these materials with the possibility of fracture [9][10][11][12][13][14]. The most typical damage caused by H in steel is embrittlement.…”

The effect of interstitial hydrogen atoms on the mechanical properties and plastic strain localization patterns in tensile tested specimens of austenitic stainless and low-carbon steels have been studied using a double exposure speckle photography technique. The main parameters of plastic flow localization at various stages of the deformation hardening have been determined in steels electrolytically saturated with hydrogen in a three electrode electrochemical cell at a controlled constant cathode potential.
