Hydrogen degradation of high-strength low-alloyed steels

Spent fuel canister for geological repository: Inner material requirements and candidates evaluation

“…On the one hand, the presence of significant amounts of hydrogen is expected to maintain reducing conditions on the near field, thus preventing or slowing fuel corrosion [23][24][25][26]. On the other hand, high hydrogen concentrations are likely to cause steel embrittlement [27][28][29] and furthermore, if enough hydrogen pressure builds up, it could affect the performance of the bentonite barrier [29][30][31][32], as bubbles may leak through the clay, possibly allowing some amount of radionuclides to leak with them or opening preferential migration paths. Therefore, the possibility of inducing or preventing hydrogen generation should not be ignored, but it can be taken into account only when more convincing evidence about this topic is available.…”

Hydrogen Embrittlement Evaluation of Micro Alloyed Steels by Means of J-Integral Curve

“…Many laboratory studies have been carried out on pipeline steels [1,10,13,15,16,17,18,19,20,21,22,23,24,25,26]; nevertheless, some aspects of this phenomenon remain poorly understood.…”

Hydrogen Embrittlement and Diffusion in High Strength Low Alloyed Steels with Different Microstructures

“…Corrosion-Fatigue (CF) can occur on sea lines as a result of the combined action of cyclic stress and corrosive environment [21,[31][32][33] . In this regard, there are numerous laboratory studies reported by different authors on HE on pipeline steels [1,[34][35][36][37][38][39][40][41][42][43] . Nevertheless, some aspects of this phenomenon remain poorly understood.…”
