TL;DR: In this article, the authors investigated the SCC susceptibility of Fe18Cr10Mn alloys with 0.3N, 0.6N and 0.5C in aqueous chloride environment using a slow strain rate test method.

Journal ArticleDOI
TL;DR: In this paper, a carburization treatment was applied to API X80 steel to understand the influence of carbon on stress corrosion cracking of pipeline steels, and they found that carbon-rich structures rather than ferrite grains remain intact and act as cathode during immersion in the acidic environment.

TL;DR: In this article, the authors evaluate and compare the resistance of Alloys 600 and 690 and their welds, such as Alloys 82, 182, 52, and 152, to EAC in simulated light water reactor environments.
Abstract: Reactor vessel internal components made of nickel-base alloys are susceptible to environmentally assisted cracking (EAC). A better understanding of the causes and mechanisms of this cracking may permit less conservative estimates of damage accumulation and requirements on inspection intervals. The objective of this work is to evaluate and compare the resistance of Alloys 600 and 690 and their welds, such as Alloys 82, 182, 52, and 152, to EAC in simulated light water reactor environments. The existing crack growth rate (CGR) data for these alloys under cyclic and constant loads have been evaluated to establish the effects of alloy chemistry, cold work, and water chemistry. The experimental fatigue CGRs are compared with CGRs that would be expected in air under the same mechanical loading conditions to obtain a qualitative understanding of the degree and range of conditions for significant environmental enhancement in growth rates. The existing stress corrosion cracking (SCC) data on Alloys 600 and 690 and Alloy 82, 182, and 52 welds have been compiled and analyzed to determine the influence of key parameters on growth rates in simulated PWR and BWR environments. The SCC data for these alloys have been evaluated with correlations developed by Scott and by Ford and Andresen.

TL;DR: In this article, the corrosion resistance characteristics of stainless steels and alloys in the context of surface film properties are discussed. But the authors do not consider the effect of the alloy composition and the environment they are exposed to.
Abstract: The service reliability of stainless steels and alloys is predominantly determined by the chemical stability of an ultrathin passive film on their surfaces. The thickness, composition and structure of such an ultrathin oxide film are all influenced by the alloy composition and the nature of the environments they are exposed to. Surface analysis of passive films formed on different grades of stainless steels under different conditions showed that chromium was significantly enriched in the surface film whereas nickel was not present in the oxidized state. Breakdown of passivity either due to mechanical damage or due to chemical attack often leads to localized corrosion in the form of pitting, crevice corrosion and stress corrosion cracking. This paper discusses the corrosion resistance characteristics of stainless steels and alloys in the context of surface film properties. Copyright © 2002 John Wiley & Sons, Ltd.

TL;DR: In this paper, the importance of strain rate in stress corrosion crack growth in some systems implies that distinction between that mode of failure and corrosion fatigue at very low frequencies can be pointless, and there are important consequences here for engineering design approaches to avoiding these modes of failure.
Abstract: Before appropriate preventative measures can be chosen to avoid any corrosion problem the latter needs to be anticipated and predictability possibly poses greater difficulties in relation to stress corrosion than many other modes of corrosion related failure. Consequently some recent work on predicting environmental requirements for stress corrosion cracking is considered, as are the less stringent requirements for corrosion fatigue. The increasing volume of evidence on the importance of strain rate in stress corrosion crack growth in some systems implies that distinction between that mode of failure and corrosion fatigue at very low frequencies can be pointless, and there are important consequences here for engineering design approaches to avoiding these modes of failure. The paper concludes with a discussion of some aspects of the various approaches to preventing environment sensitive fracture.
