7.3.4.5Stress Corrosion Cracking (SCC) Corrosion in the presence of tensile stress accelerates the damage to the metal surface. The mechanisms arenot well understood, but it is thought that applied or internal stress causes atoms to leave the anodic tips of incipient cracks, thereby sharpening the...
