Abstract

The susceptibility of martensitic Alloy EP-823 to stress corrosion cracking was evaluated in neutral and acidic aqueous environments by using constant-load and slow-strain-rate test methods at ambient temperature and 90oC. The results indicate that this alloy may not suffer from cracking in the neutral solution, but will undergo failure in the acidic medium. The true failure stress and the conventional ductility parameters were reduced due to the synergistic effect of acidic pH and elevated temperature. The fractographic evaluations revealed ductile failure in the neutral solution, but intergranular brittle failure was observed in the acidic environment.
