摘要	The effect of intergranular carbides on the stress corrosion crack (SCC) initiation of alloy 690 in high-temperature hydrogenated water was systematically studied. Irrespective of the aging temperature, the resis-tance to SCC initiation continuously increases with increasing carbide coverage. The understanding of carbide effects was further advanced. Mechanically, the carbide mitigates the breach of surface oxide film over the grain boundary by suppressing the local apparent plastic strain. The carbide also greatly diminishes grain boundary migration by retarding the diffusion of Cr. More importantly, it decomposes when exposed to the environment and serves as Cr source for forming protective oxide film.
