“…The result of Es‐Said's work indicated that mobile dislocations were able to transport hydrogen to material weak links much more rapidly than lattice diffusion at extremely short time. HE mechanisms were related closely with the dislocation mobility in the presence of hydrogen . A hydrogen atmosphere must move with a dislocation to allow the hydrogen‐enhanced dislocation motion to exhibit more than a transitory effect.…”

Hydrogen‐induced degradation of X80 pipeline steel was investigated through a high strain rate tensile test (2 × 10−4/s) with interposed unloading, reloading, aging at 30°C, or annealing at 200°C with or without hydrogen charging. The results indicated that plasticity degradation does not occur in the hydrogen‐precharged specimens; however, hydrogen embrittlement occurs in the reloading stage when the specimens are charged with hydrogen in the unloading stage after applying a prestrain. Interposed aging at 30°C or annealing at 200°C can also increase the degradation. It indicates that the hydrogen traps caused by the strain along with hydrogen charging are the major source of dislocations. The formation of a hydrogen atmosphere around mobile dislocations, which is related to the rates of hydrogen diffusion and dislocation movement, plays an important role in the degradation process. Both pinning and depinning of dislocations affect plasticity degradation.

This requirement incorporates a natural dependence on strain rate, stress, and temperature.…”
