... intergranular attack iodine stress corrosion cracking titanium Titanium alloys are considered for structurally critical applications such as airframe components, aircraft hydraulic systems, air engine components, rockets, missiles, space craft, tanks, etc. For that reason, the stress corrosion...

... pitting corrosion and intergranular attack are observed on specimens polarized into the transpassive dissolution region. Under open-circuit conditions, the corrosion potential is observed to shift in the positive direction with time, with a steady state being achieved after about four months of exposure...

... that Alloy C-276 performed better than UNS N08367 and UNS N08028 in both the sensitized and the solution-annealed conditions. ‡ Corresponding author. E-mail: [email protected] . May 2004 December 2004 NACE International 2005 Alloy C-276 chloride intergranular attack...

.... SCC was observed in all the systems studied and the crack propagation rate was found to vary depending on the size of the solvent molecule. As the solvent molecular weight increased, the crack propagation rate decreased. Prior to crack propagation, intergranular attack was found in all the solutions...

...H. Kawamura; H. Hirano; M. Koike; M. Suda The inhibitory effect of boric acid (H₃BO₃) on the intergranular attack and stress corrosion cracking (IGA/SCC) propagation of steam generator (SG) tubing was studied under accelerated test conditions. Based on an analysis of stress...

... intergranular attack nickel stress corrosion cracking The susceptibility of Ni-based Alloy 600 (UNS N06600) ⁽¹⁾ to intergranular stress corrosion cracking (IGSCC) in high-temperature water at low electrochemical potentials has been recognized for 40 years since the initial work of Coriou...

... on the susceptibility to intergranular attack (IGA) and stress corrosion cracking (SCC) of alloy 600 (UNS N06600) has not been established clearly in laboratory tests or under operating conditions. The present work studied the effect of different compounds of silicon, such as silica (SiO₂) and sodium...

...H. Kawamura; H. Hirano The effect of stress intensity factors (K) at the intergranular attack and stress corrosion crack (IGA/SCC) tips on the IGA/SCC propagation behavior of steam generator (SG) tubing was studied under accelerated test conditions. Values of K at the IGA/SCC crack tips were...

... H₂SO₄ solution. Tests were conducted at temperatures and pressures up to 500°C and 38 MPa, respectively. Corrosion in the oxygenated acidic solution started ~ 150°C with intergranular attack (IGA). Above 250°C, the whole surface of the alloy was attacked, and shallow pits and deep IGA appeared...
