Abstract
Intergranular stress corrosion cracking tests by using fretting contacts with high stress ratio were conducted. All of the initiated cracks were intergranular manner due to crevice corrosion and removal of surface oxide layer by frictions. The crack growth rate revealed higher value than that of large cracks, which demonstrated small crack effect on intergranular cracking.
