“…Also, the time required for crack initiation and the time for crack propagation cannot be individually estimated. Despite these drawbacks, this test method has been widely applied to study the sulfide cracking (Du, Tao, & Li, 2004), the chloride cracking (Bauernfeind, Haberl, Mori, & Falk, 2006;Jin, 1994) and the SCC of high-strength steels (Oehlert & Atrens, 1996).…”

The mechanisms of stress corrosion cracking (SCC) and hydrogen embrittlement were recently reviewed by Lynch in this journal. The present review, in contrast, focuses on the rate-limiting step of the SCC of low-alloy high-strength steels in water and particularly focuses on the influence of the applied stress rate on the SCC of low-alloy high-strength steels. Linearly increasing stress tests of low-alloy high-strength steels in distilled water indicated that the stress corrosion crack velocity increased with increasing applied stress rate until the maximum crack velocity, corresponding to vII in fracture mechanics tests in distilled water. Moreover, the crack velocity was dependent only on the applied stress rate and was not influenced by the steel composition. The rate-limiting step could be the rupture of a surface film, which would control the rate of metal dissolution and/or the production and transport of hydrogen to the crack tip or to the regions ahead of the crack tip.

“…The percentage of strain-induced martensite and deformation twins also influence the SCC initiation, due to the higher susceptibility of martensite and deformation twins to suffer SCC than the austenitic microstructure. This difference can be seen in literature, where martensitic stainless steels subjected to SCC in 3.5 wt.% NaCl at room temperature (25 • C) experience intergranular fracture with the formation of secondary cracks [141,142]; while austenitic stainless steels needed higher temperatures to develop SCC (>100 • C) [137,143], lower pH (pH < 3) [144,145], or higher chloride content (24.2 wt.% NaCl) in the case of exposure to alkaline solutions (sat. CaCl 2 ) [143,146].…”

Twinning-induced plasticity (TWIP) steels have higher strength and ductility than conventional steels. Deformation mechanisms producing twins that prevent gliding and stacking of dislocations cause a higher ductility than that of steel grades with the same strength. TWIP steels are considered to be within the new generation of advanced high-strength steels (AHSS). However, some aspects, such as the corrosion resistance and performance in service of TWIP steel materials, need more research. Application of TWIP steels in the automotive industry requires a proper investigation of corrosion behavior and corrosion mechanisms, which would indicate the optimum degree of protection and the possible decrease in costs. In general, Fe−Mn-based TWIP steel alloys can passivate in oxidizing acid, neutral, and basic solutions, however they cannot passivate in reducing acid or active chloride solutions. TWIP steels have become as a potential material of interest for automotive applications due to their effectiveness, impact resistance, and negligible harm to the environment. The mechanical and corrosion performance of TWIP steels is subjected to the manufacturing and processing steps, like forging and casting, elemental composition, and thermo-mechanical treatment. Corrosion of TWIP steels caused by both intrinsic and extrinsic factors has posed a serious problem for their use. Passivity breakdown caused by pitting, and galvanic corrosion due to phase segregation are widely described and their critical mechanisms examined. Numerous studies have been performed to study corrosion behavior and passivation of TWIP steel. Despite the large number of articles on corrosion, few comprehensive reports have been published on this topic. The current trend for development of corrosion resistance TWIP steel is thoroughly studied and represented, showing the key mechanisms and factors influencing corrosion processes, and its consequences on TWIP steel. In addition, suggestions for future works and gaps in the literature are considered.

“…3, 5, 8, 10, 11 Some grades of austenitic stainless steels, including 304 and 316, have long been recognized as less susceptible to AISCC below 60°C, which encouraged end-users to expose these materials to corrosive environments below the believed threshold temperature. 9,11,42,43 However, SCC at ambient temperatures has been reported in harsh corrosive environments and has questioned the "threshold" temperature concept. 14-16, 44, 45 The threshold concept has not been revisited, however, instead the temperature under which pitting corrosion may not occur (critical pitting temperature), which is around 0°C and 10°C for 304 and 316 stainless steel respectively 46 , has been argued as a safe approach for ILW storage.…”

Type 304 (UNS S30400) austenitic stainless steel was exposed for 6 months under elastic (0.1%) and elastic/plastic (0.2%) strain to MgCl2 and mixed MgCl2:FeCl3 droplets with varying chloride deposition densities (1.5-1500 µg/cm²) at 30% relative humidity (RH) and 50°C. The occurrence of pitting corrosion, crevice corrosion, atmospheric chloride-induced stress corrosion cracking (AISCC) and hydrogen embrittlement (HE) was observed, and the average crack growth rates estimated. Exposure to elastic/plastic strain resulted in longer and more severe cracks. AISCC was found at chloride deposition densities down to 14.5 µg/cm², whereas no cracks were seen at lower deposition densities, with cracks developing at pit or crevice corrosion sites. More severe cracks were seen under MgCl2 droplets as contrasted to mixed MgCl2:FeCl3 salt droplets, which were seen to promote more localized corrosion sites with deeper penetration and in conjunction with shorter crack lengths. Differences in AISCC propagation rates and associated crack morphologies are discussed in relation to understanding long-term atmospheric corrosion exposures.
