2005:60 Research and Service Experience with Environmentally-Assisted Cracking in Carbon and Low-Alloy Steels in High-Temperature Water
cracking of carbon and low-alloy steels in high-temperature water are reviewed, with special emphasis on the primary pressure-boundary components of boiling water reactors. The main factors controlling the ... for further research are identified. In spite of the absence of stress corrosion cracking in the field, several unfavourable critical parameter combinations, which can lead to sustained, fast stress corrosion...

2009:15 Improvement and Validation of Weld Residual Stress Modelling Procedure
Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important ... research results in the field of WRS. The major changes applied in the new weld residual stress modelling procedure are: Improved procedure for heat source calibration based on use of analytical solutions...
