Abstract [en]

It is well known that Alloy 690 is highly resistant against primary water stress corrosion cracking (SCC), yet not completely immune. Cold work, which is known to accelerate SCC crack growth rates (CGRs), has been shown to occasionally enhance the CGR in Alloy 690 base metal to alarmingly high levels. While Alloy 690 is not typically used in a heavily cold worked condition, effective plastic strains of comparable level have been estimated in Alloy 690 heat affected zone (HAZ). Much recent work on Alloy 690 has been focused on build up data in order to clarify whether or not these high CGRs are of concern for operating power plants.

How cold work affects SCC CGR is still unclear. Based on trends in experimental data, some factors are believed to increase CGRs. The clearest trend is that of crack orientation. Aligning the plane and direction of crack growth with those of cold deformation generally yields a much higher CGR than other orientations. Inhomogeneous microstructure due to banding, fractured second phase particles and grain boundary voids also seem to enhance crack growth. The presence of these factors does however not guarantee high CGRs, and the lack of them does not guarantee low CGRs.
