A mechano-chemical investigation of SCC mitigation in pre-strained Alloy 600 in a simulated boiling water reactors environment with high oxygen concentrations
Source abstract
Abstract
This study clarifies the mechano-chemical role of surface treatments on the SCC of sensitized Alloy 600. We compared 400-grit grinding, Scotch-Brite polishing, and CWJP under “bend-then-treat” CBB testing. While grinding caused severe cracking, CWJP provided complete immunity during a 500 h CBB testing. This occurred despite the CWJP surface having the highest GND density and roughness. The dominant protective mechanism was a relatively deeper, higher-magnitude CRS field induced by CWJP. This CRS mechanically counteracts applied loads and electrochemically stabilizes the surface by retarding DO diffusion, as confirmed by DFT. Engineering deep CRS is thus paramount for mitigating SCC.
