摘要: In this study, the use of thermoelectric power (TEP) measurements as a nondestructive method for determination degree sensitization (DOS) in UNS S31803 duplex stainless steel (DSS) is presented. Samples were aged times up to 240 h and subjected double loop electrochemical potentiokinetic reactivation (DL-EPR) test calculate DOS induced. The correlation between TEP evaluated by DL-EPR indicates that coefficient sensitive gradual microstructural changes produced thermal aging may be used monitor susceptibility intergranular corrosion DSS.
