Corrosion fatigue under the load of low frequency and bigh mean stress has been generallydefined as stress corrosion fatigue(SCF).It is a specific failure process due to the inter-action between stress corrosion cracking(SCC) and corrsion fatigue(CF),the effectsof which on fracture characteristics,including crack initiation and propagation.servicelife and cracking mode have not been investigated systematically.The purpose of this pa-per was to study the environment-sensitive fracture behaviour of OCr18Ni9Ti austeniticstainless steel under the load of different fiequencies and high mean stress in boilingMgCl_2 solution.The interaction between SCC and CF would be emphasized.
