TL;DR: In this article, it was found that small amount of impurities in environments affects the initiation process, but do not affect the propagation process of SCC, which is rationally explained by the bound water model of passive film and HSAB (Hard and Soft Acid and Base) rule.

TL;DR: In this article, the effects of dissolved hydrogen (DH) and inner surface finish condition of the hollowed specimen on stress corrosion crack initiation and small crack growth behaviors of 316 stainless steel were investigated in high temperature water with various DH levels.

TL;DR: In this paper, the authors studied the effects of hydrogen on the ductility loss and the intergranular fracture of hydrogen-charged (32 wt ppm) tensile specimens of alloy 600.
Abstract: Tensile tests were conducted at various temperatures (77 to 550 K) and strain rates (10−5 to 10−1 s−1) in order to study the effects of hydrogen on the ductility loss and the intergranular fracture of hydrogen-charged (32 wt ppm) tensile specimens of alloy 600. The H-induced intergranular cracking was shown to require H segregation to grain boundaries (GBs) during plastic deformation. The concordance between the temperature/strain rate domains, where H-induced intergranular rupture of alloy 600 is observed and those of H transport by dislocations, is in favor of a major influence of this mechanism of H transport on the intergranular rupture of H-charged alloy 600 in the 180 to 500 K temperature range. The possible contribution of this mechanism to intergranular stress corrosion cracking (IGSCC) of alloy 600 in the pressurized water reactor (PWR) environment is discussed.

TL;DR: In this paper, compressive residual stresses can be developed by underwater plasma transferred arc welding to prevent hot cracking and He embrittlement that can develop during welding or stress corrosion cracking that can developed subsequent to the welding operation.
Abstract: Compressive residual stresses can be developed by underwater plasma transferred arc welding. The development of these compressive stresses act to prevent hot cracking and He embrittlement that can develop during welding or stress corrosion cracking that can develop subsequent to the welding operation.
