摘要: This article investigates the mechanisms governing process of alloy 600 stress corrosion cracking (SCC). Several critical points have been selected. First, deleterious influence cathodic polarization on SCC resistance has assessed by slow strain rate tests (SSRTs) in primary water at 360 °C. The effects crack initiation and propagation distinguished. Second, a global hydrogen embrittlement also studied different temperatures from 25 °C to Finally, use single crystals allowed clear separation mechanisms. Transgranular precisely observed described. possible for polycrystals are then discussed.
