“…SCC crack often initiated at the surface of the specimen, so the surface machining has an important influence on the SCC sensitivity . Residual stress increased and persistent slip bands (PSBs) often formed on the surface and sub‐surface of specimens during machining operation, which finally promote the crack initiation in corrosive environment.…”

The stress corrosion cracking (SCC) behaviors of Z3CN20.09M, 304L, and 316L austenitic stainless steels (SSs) after milling operation in boiling magnesium chloride solution were investigated by scanning electron microscopy (SEM), X‐ray diffraction, and 3D profilometer. The experimental results indicated that the roughness and residual stress increased with increasing feed rate of all specimens. The depth of deformation layer after milling operation reached about 150 µm shown as persistent slip bands (PSBs) were formed, leading to hardness enhanced obviously. After SCC tests in boiling magnesium chloride solution, the crack densities increased with increasing feed rate of the Z3CN20.09M SS specimens. However, the crack densities decreased as well as the intergranular (IG) cracking percentages increased with increasing feed rate of the 304L and 316L SS.

“…Austenitic stainless steels (SSs) have been widely used in chemical, petrochemical and nuclear power industries due to their outstanding machinability, corrosion resistance and mechanical properties . Z3CN20.09M, 304L, and 316L SSs were widely used in pressurized water reactor (PWR) nuclear power plant as primary coolant pipe serviced in high temperature water environment .…”

“…The result indicated that the residual stress induced by surface machining remarkably promoted crack initiation. Previous studies often focused on the effect of applied stress, strain rate or loading mode on the SCC cracking behavior . However, the detailed relationship between the crack initiation behavior and residual stress level of Z3CN20.09M, 304L, and 316L SSs were not clear until now.…”

The effect of residual stress on the stress corrosion cracking (SCC) behaviors of Z3CN20.09M, 304L and 316L austenitic stainless steels (SSs) in boiling magnesium chloride solution were investigated by X‐ray diffraction, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The residual stress of surface and the hardness tested on the cross section of specimens induced by milling operation was decreased with increasing annealing temperature. The crack densities were also decreased with increasing annealing temperature of the specimens, and the SCC did not occur after annealed at 600 °C for 3 h except 316L SS when tested in boiling magnesium chloride solution. Crack initiation mechanism related to the damaged effect on grain boundary during milling operation was analyzed. The double loop electrochemical potentiokinetic reactivation (DL‐EPR) tests indicated that the effect of annealing treatment up to 600 °C on intergranular (IG) corrosion susceptibility of 304L and 316L SSs was minor, while it remarkably increased of the Z3CN20.09M SS.

“…Many studies on crack initiation [24,25] and crack growth [26][27][28][29] have been carried out on materials exposed to high-temperature water, which is simulated environment in boiling water reactors (BWRs) and pressurized water reactors (PWRs). Andresen et al [26] evaluated crack growth of non-sensitized stainless steel in high-temperature water, and reported the effects of yield stress and corrosion potential on crack growth.…”
