TL;DR: In this article, the authors found that grain boundary cracking susceptibility was associated with slip continuity, indicating that the strain accommodation at the boundary is related to cracking resistance, and higher susceptibility was also found at grain boundaries adjacent to grains with low Schmid factor or high Taylor factor.
Abstract: Irradiation assisted stress corrosion cracking may be linked to the local slip behavior near grain boundaries that exhibit high susceptibility to cracking. Fe–13Cr–15Ni austenitic steel was irradiated with 2 MeV protons at 360 °C to 5 dpa and strained in 288 °C simulated BWR conditions. Clusters of grains from the experiment were created in an atomistic simulation and then virtually strained using molecular dynamic simulation techniques. Cracking and grain orientation data were characterized in both the experiment and the simulation. Random high angle boundaries with high surface trace angles with respect to the tensile direction were found to be the most susceptible to cracking. Grain boundary cracking susceptibility was also found to correlate strongly with slip continuity, indicating that the strain accommodation at the boundary is related to cracking resistance. Higher cracking susceptibility was also found at grain boundaries adjacent to grains with low Schmid factor or high Taylor factor. The basic trends reported here are supported by both the experiments and the simulations.

TL;DR: In this article, the role of sulfate-reducing bacteria (SRB) in SCC susceptibility has been investigated in a near-neutral pH soil solution by slow strain rate tests and the relationship between plasticity loss and the permeable hydrogen concentration were established for the steel in the soil solution, regardless of under open circuit potential or cathodic potentials, in both the sterile and SRB inoculated conditions.
