TL;DR: In this article, the effect of prior deformation on SCC growth rates of Alloy 600 materials in a simulated pressurized water reactor primary water environment was studied, and the results showed significant amounts of plastic strain in the Alloy 600 weld heat-affected zone (HAZ) and in the cold worked Alloy 600 material.

TL;DR: In this paper, the role of stress on interface oxidation kinetics was analyzed in Alloy 600 heat-affected zone specimens with higher intergranular stress corrosion cracking growth rates than that in the base metal in simulated pressurized water reactor water environments.

TL;DR: In this paper, the stress corrosion cracking (SCC) growth kinetics for a cold worked 316L stainless steel was continuously monitored in high purity water at different temperatures and dissolved oxygen (DO) levels under a K (or K max ) of 30MPa/m 0.5.

TL;DR: In this article, an alternating current potential drop (ACPD) technique was used to monitor the crack growth kinetics throughout the tests, and three kinds of crack growth kinematics were identified, i.e., increasing with time then becoming steady, being constant during the whole period, decreasing with time, and becoming steady.

TL;DR: In this article, the distance from the weld fusion line in an Alloy 690 heat-affected zone, micro-hardness decreases, kernel average misorientation decreases and the fraction of Σ3 boundaries increases.
