Book Description
High-strength steels are susceptible to delayed cracking under suitable conditions. Frequently such a brittle failure occurs at a stress that is only a fraction of the nominal yield strength. Considerable controversy exists over whether such failures result from two separate and distinct phenomena or whether there is but one mechanism called by two different names. Stress-corrosion cracking is the process in which a crack propagates, at least partially, by the stress induced corrosion of a susceptible metal at the advancing tip of the stress-corrosion crack. There is considerable evidence that this cracking results from the electrtrochemical corrosion of a metal subjected to tensile stresses, either residual or externally applied. Hydrogen-stress cracking is cracking which occurs as the result of hydrogen in the metal lattice in combination with tensile stresses. Hydrogen-stress cracking cannot occur if hydrogen is prevented from entering the steel, or if hydrogen that has entered during processing or service is removed before permanent damage has occurred. It is generally agreed that corrosion plays no part in the actual fracture mechanism. This report was prepared to point out wherein the two fracture mechanisms under consideration are similar and wherein they differ. From the evidence available today, the present authors have concluded that there are two distinct mechansims of delayed failure. (Author).
Effect of Hydrogen Gas on High Strength Steels

Pages : 22
Book Description
A possible failure mode of high strength steels that are used in hydrogen gas-cooled turbine generators can be described by a combination of environment-assisted crack initiation, crack propagation by fatigue, and sustained load and final fracture. Therefore, a project was initiated to study the fracture properties in hydrogen and hydrogen sulfide (H2S) gas of two high strength steels, 3.5 nickel-chromium-molybdenum-vanadium ferritic and 18Mn-4Cr austenitic, which are commonly used for generator end rings. Two specimen types were employed, blunt notch specimens for crack initiation studies and precracked specimens for crack propagation and stress corrosion cracking studies. Tests were conducted to determine crack initiation due to incrementally rising load in H2S, crack propagation due to fatigue loading in hydrogen (H2), and KIscc in H2. This paper presents experimental data and provides metallurgical evidence to show that the failure mechanism in the specimens is environment assisted.

Book Description
Research and commercial activity in developing hydrogen as a fuel is driving increased attention on hydrogen-materials interactions. In particular, a renewed and intensifying interest in developing hydrogen fuel cells has prompted extensive research with the objective to enable the safe design of components for transporting and storing hydrogen fuel. This volume is the proceedings from the premier conference on hydrogen effects in materials, bridging scientific research and engineering applications. The proceedings volume highlights several themes: the technological importance of hydrogen effects on structural materials; the impact of bridging science and engineering; and the opportunity to apply new research tools, including simulation techniques as well as experimental methods.
