| Research Abstract |
Using highly adjusted test materials, following items were investigated and evaluated;1) intergranular stress corrosion initiation atress and intergranular local stress, 2) stacking fault energy near grain boundaries, 3) identification of oxide film by in-situ X-ray diffraction, 4) long-term stress corrosion cracking characterization. Based onthese analyses, the physicochemical mechanism on the intergranular stress corrosion cracking of non-sensitized materials was clarified, from the view points of stress, materials and environment.
