“…In order to increase the resistance to intergranular corrosion of nonsensitized stainless steels, the content of S, P, B and Si minor elements, which preferentially segregate at the grain boundaries during heat treatments of steels, must be reduced [15,113]. the relationship between residual concentrations, structure and energy of grain boundaries, and intergranular corrosion resistance is complex and not yet predictable.…”

“…It is clear that the localized attack seen in SCC and"intergranular corrosion arises through chromium depletion (although intergranular attack can occur in strongly oxidizing environments withoutchromiumdepletion if certain elements have segregated to the grain boundaries). 35,36 The classical model for sensitization is that of Stawstrom and Hillert. 37 Stainless steels are susceptible to sensitization only if they contain a sufficient level of carbon.…”

The interactions of composition, microstructure, and corrosion processes have been studied extensively. In stress-corrosion cracking (SeC)-where mechanical stresses can accelerate failure-material chemistry and microstructure can alter the corrosion attack as well as influence deformation and fracture. The mechanisms through which these effects are felt, however,do not apply universally and are often difficult to elucidate. This article reviews mechanisms wherein corrosion behavior is the main influence, examining how segregation and precipitation at grain boundaries affects intergranular Sec.

“…Other researchers, for example Li et al [8] and Yonezawa et al [9], also observed that Si significantly affected the environmentally assisted corrosion (EAC) behavior of the simulated grain boundary (GB) steels by promoting intergranualr cracking in PWR. For P and S, it seems that their segregations have a little effect on promoting environmental cracking in high temperature water [10,11]. Obviously, the real basic mechanisms of IASCC nucleation and propagation are very critical to understand the above phenomena.…”
