摘要：

In laboratory tests conducted to simulate conditions leading to intergranular stress corrosion cracking (IGSCC) of alloy 600 steam generators tubings in pressurized water reactors, both the slow strain rate (SSR) technique and the reverse U-bend (RUB) technique are mostly used. Hydrogen is commonly used to scavange oxygen which is produced by radiolytic decomposition of water. However, it has been found recently that H//2 promotes IGSCC of Alloy 600 in high temperature water. The SSR technique based on use of tensile specimens with a cold-pressed hump appears to be more reliable and more sensitive to IGSCC than the RUB technique.
