Abstract EN
The stress corrosion cracking (SCC) resistance of cold deformed thermally treated (TT) Alloy 690 has been questioned in recent years.
As a step towards understanding its relevancy for weld deformed Alloy 690 in operating plants, Alloy 690 base metal and heat affected zone (HAZ) microstructures of three mockup components have been studied.
All mockups were manufactured using commercial heats and welding procedures in order to attain results relevant to the materials in the field.
Thermodynamic calculations were performed to add confidence in phase identification as well as understanding of the evolution of the microstructure with temperature.
Ti(C,N) banding was found in all materials.
Bands with few large Ti(C,N) precipitates had negligible effect on the microstructure, whereas bands consisting of numerous small precipitates were associated with locally finer grains and coarser M23C6 grain boundary carbides.
The Ti(C,N) remained unaffected in the HAZ while the M23C6 carbides were fully dissolved close to the fusion line.
Cold deformed solution annealed Alloy 690 is believed to be a better representation of this region than cold deformed TT Alloy 690.
