[3C11] SCC Initiation and Propagation Mechanisms of Stainless Steel in Simulated PWR primary water
(1) Investigation from Nanoscale Analysis of Crack Tip
Keywords:stainless steel, stress corrosion cracking, nanoscale analysis of crack tip, TEM, SCC initiation and propagation mechanisms
Based on the results of crack tip observation of stress corrosion cracking (SCC) that propagated in 20% cold-worked 316 stainless steel in PWR primary system simulated water at 320℃ and 360℃ using TEM and STEM/EDS, we discuss the SCC propagation mechanism.
