Some fundamental aspects of thermally activated processes involved in stress corrosion cracking in high temperature aqueous environments

Effects of surface treatments and temperature on the oxidation behavior of 308L stainless steel cladding in hydrogenated high-temperature water

“…The effect of temperature on SCC is complex in terms of temperature-related corrosion potential, pH, conductivity and hydrogen fugacity et al For structural materials in simulated light water reactor environments, temperature-dependent SCC growth mainly includes two types, that are: crack growth increases monotonically with temperature and crack growth shows the peak at a threshold temperature [9,10,[55][56][57]. However, it is reasonable to conclude that austenitic alloys with some δ-ferrite can effectively hinder crack propagation due to the special morphology, lattice structure and self-diffusion effect of δ-ferrite.…”

Influence of Dissolved Hydrogen on Stress Corrosion Cracking Susceptibility of Nickel Based Weld Alloy

“…Places which the operating temperatures are high develop cracks more rapidly than regions where the operating temperatures are lower. It has also been observed that crack growth rates of nickel-based alloys and weld metals in simulated PWR primary water environments generally increase with increasing temperature (Nishikawa et al, 2004, Lu et al, 2008, Schvartzman et al, 2009). …”

Evaluating the Effect of Hydrogen on the Tensile Properties of Cold-Finished Mild Steel

“…Metals with body-centered cubic and hexagonal close-packed structures are most prone to HE, whereas face-centered cubic metals exhibit little to no susceptibility to HE. Hydrogen has a very high mobility in the BCC lattice of carbon and low-alloy steels [2,4]. HE failures are low stress events that result in brittle fractures and frequently cause massive financial losses and disastrous events.…”
