  • Behaviour of activation-reactivation and intergranular attack (IGA) patternhas been stubied by means of electrochemical potentionkinetic reactivation (EPR).The degree of susceptibility to intergranular stress corrosion cracking (IGSCC) iscomparable by both constant strain test and slow strain rate test in high temperaturewater. Results reveal that a good agreemcnt between RPR and IGSCC is found.EPR may be carried out as a nondestructive inspection (NDI) in practice to pre-dict the degree of sensitization to IGSCC of welded stainless steel in nuclar powersystems.
