This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The stress corrosion cracking (SCC) of components which are fabricated from austenitic stainless steel has been observed in the primary circuit of pressurised water reactors (PWR). In recent years it has become an increasing concern that cold work can induce susceptibility to SCC in these materials, even when exposed to good-quality flowing coolant. Laboratory studies which were launched in response to this observation have confirmed that SCC susceptibility is enhanced by cold work. The intention of this study is therefore to investigate the link between the effects of cold work on the material and the susceptibility to SCC. The investigation has been conducted on a grade 304 austenitic stainless steel. Characterisation of the microstructure and mechanical properties has been carried out in the annealed condition, and following cold rolling to a reduction in thickness of 20 %. The cold rolled material has then been subjected to SCC tests in simulated PWR primary circuit coolant. Two types of test were utilised: slow strain rate tests (SSRTs) were carried out in order to investigate the initiation of cracks from a smooth surface and constant load tests using pre-cracked specimens were used to investigate the crack propagation behaviour. In both types of test the SCC produced was predominantly intergranular. The SSRTs revealed that the most susceptible grain boundaries separated grains which had dissimilar deformation microstructures (one grain deformed heavily by planar bands, the other more homogenously). It was also observed that initiation could occur on a grain boundary which is adjacent to an annealing twin. In both microstructural configurations the susceptibility is likely to be due to the deformation incompatibility across the failed boundary, possible indicating that shear at the boundary is important for the initiation of cracking. The crack propagation behaviour of the rolled material was particularly anisotropic; regardless of the loading direction (specimens were manufactured to allow loading along the rolling, transverse and normal plate directions) cracking was observed to occur parallel to the rolling-transverse plane. The origin of this behaviour was explored in terms of preferential alignment of the deformation microstructure and the anisotropic mechanical properties of the rolled plate. Limited transgranular cracking was also observed, which occurred along oxidised deformation bands. The results overall indicate that heterogeneous deformation between different regions of the material, and preferential alignment of the deformation microstructure are important with respect to the SCC susceptibility of the rolled material.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress corrosion cracking behavior is a matter of concern for structural materials, namely stainless steels and nickel alloys, in nuclear power plants. High levels of cold work have been shown to both reduce crack initiation times and increase crack growth rates. Cold working has numerous effects on a material, including changes in microstructure, mechanical properties, and residual stress state, yet is typically reported as a simple percent change in geometry. There is need to develop a strategy for quantitative assessment of cold work level in order to better understand stress corrosion cracking test data. Six assessment methods commonly performed alongside stress corrosion cracking testing- optical microscopy, electron backscatter diffraction, x-ray diffraction, tensile testing, hardness testing, and residual stress measurement- are evaluated with respect to their ability to quantify the level of cold work in a component. The test material is stainless steel 316L plate that has been cold-rolled to three conditions: 0%, 20%, and 30%. Measurement results for each assessment method include correlation with cold work condition and repeatability data. Measured values showed significant spatial variation, illustrating that cold work level is not uniform throughout a component. Mechanical properties (tensile testing, hardness) were found to correlate most linearly with cold work condition. Significant residual stresses were observed in all three orthogonal directions. General suggestions for a cold work characterization methodology are provided.

This book was released on 1966 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book excerpt: In recent work on stress corrosion cracking, the role of alloying elements which may effect dislocation distribution and cracking has been discussed. Nitrogen has been introduced into austenitic stainless steels in the solid state from NH3/H2 mixtures at temperatures in the range 600-750C. The resistance to cracking is markedly improved. The reasons for this improvement are under investigation. (Author).
