Effect of residual stress on the stress corrosion cracking in boiling magnesium chloride solution of austenite stainless steel

Abstract

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.

Mitigation of chloride driven stress corrosion cracking susceptibility of 316L austenitic stainless steel using plasma sprayed TiO2 coating

“…In regards to this thought, other approaches should be considered. The idea of stress control on the subject material provides considerable protection against the stress corrosion cracking susceptibility [13][14][15][16][17][18]. This approach comprises of reduction of applied and residual stresses, and introduction of compressive surface stresses.…”

Influence of Impact Velocity on the Residual Stress, Tensile Strength, and Structural Properties of an Explosively Welded Composite Plate

“…A compressive residual stress state is known to increase fatigue strength [18], and can be a cause of dimension instability during cutting or other manufacturing processes. In contrast, a tensile residual stress state tends to be undesirable as it accelerates crack growth and can induce stress-based corrosion cracking [19,20]. Nagano et al [21] noted that a passive oxide film in pure zirconium and its alloys ruptured because of stress in corrosive environments depending on temperature and HNO 3 concentration.…”

Effect of Cl− Concentration on the SCC Behavior of 13Cr Stainless Steel in High-Pressure CO2 Environment

“…Stress corrosion cracking (SCC) has been recognized as a degradation issue in tubing and casing materials in recent years [1][2][3]. The tubing and casing materials contacting with aqueous solutions containing CO 2 and Cl − undergo severe corrosion, such as localized corrosion and SCC [4][5][6][7][8]. Therefore, the materials used for pipelines are mainly selected based on their performance under increasingly severe environments [9,10].…”
