Figures 2 and 3 imply that both the gliding dislocation by dynamic plastic deformation and the strain-induced martensite, and of course the diffusible protons, are necessary for hydrogen embrittlement. The grain boundary separation occurs when these three condition were simultaneously satisfied.
The hydrogen embrittlement sensitivity to the bainitic steels used in this study is investigated by SSRT.
The high carbon content resulted in the formation of martensite at the fusion line in the HAZ, and it is well documented that untempered martensite can cause increases in hydrogen embrittlement [1, 29, 37, 38].

Metal fractures related to "environmentally induced cracking" are often associated with stress corrosion cracking (SCC) or hydrogen embrittlement (HE) mechanisms [7-9].

These services currently include tensile, hardness, stress rupture, creep, impact, proof load, bend, hydrogen embrittlement, fracture mechanics and a number of additional test methods.
Research papers included cover such topics molecular modeling of structure and reactivity at the metal/environment interface, processes at metal-solution interfaces: modeling and simulation, adsorption of organic inhibitor molecules on metal and oxidized surfaces studied by atomistic theoretical methods, and multiscale modeling of hydrogen embrittlement. Each chapter includes a conclusion and a comprehensive list of references.

"Talk to any engineers who knows anything, and they'll tell you it can't be done." [Pause.] "Including me, until I saw that." (The issue: hydrogen embrittlement. Says Mark Ellis, senior associate at Munro: "When you try to weld the two together, the die casting material tends to crumble.
In the end, the committee investigating the failed rods determined that hydrogen embrittlement was the culprit.
