It was also found that due to the different near-surface chemical composition of the as-received Alloy 690TT specimen compared with the ground and the polished specimens, the surface roughness parameters do not have a regular correlation with the rate of the ORR and the values of the E corr...
Specimens from alloy 690 plate, with chemical composition (wt.%): 0.03C, 0.28 Si, 0.25 Mn, 29.0 Cr, 0.02 Cu, 9.5 Fe, 0.002 S and balance Ni, were cut to cuboid with a dimension of 10 mm × 10 mm × 2 mm for test. The specimens were solution annealed at 1100 °C for 1 h ...

The present work is to investigate the corrosion behavior of Alloy 690 exposed to aerated SCW with different temperature and time, and to characterize the phase composition, morphologies and chemical composition of the oxide films formed on the surface of Alloy 690. The related corrosion mechanism ...

and presumably, remain above somecritical level. However, higher Cr contents in nickel-base alloy 690 vs. 600 has been shown to provide significantly higher resistance to IGSCC inpressurized water reactorenvironments as well, where the potential is very low. Thus, high Cr+Ni has the potential ...
The alloy (Alloy690) having the chemical composition shown in Table 1 was melted in vacuum and cast into an ingot. The ingot was subjected to hot forging to make a billet. And the billet was formed into a tube shape by hot extrusion process. The tube was made to have an outer diameter...
