摘要: The impact of solution and sensitization treatments on the intergranular corrosion (IGC) austenitic stainless steel (316) was studied by electrochemical potentiodynamic reactivation (EPR) test, results showed degree (DOS) decreased as treatment temperature time went up, but it increased prolonged. Factors that affected IGC were investigated field emission scanning electron microscope (FE-SEM) back-scattering diffraction (EBSD). Furthermore, precipitation evolution Cr-rich carbides distribution chromium concentration simulated cellular automaton (CA), clearly showing effects IGC.
