Background

Stress corrosion refers to the breakdown of a metal in a corrosive medium under the action of tensile stress. This corrosion is generally through the grain, so-called transgranular corrosion. Stress corrosion is a material failure process resulting from the combined effects of strain and corrosion caused by residual or applied stress. Stress corrosion induced cracking of a material is known as stress corrosion cracking. Stress corrosion is generally considered to be both anodic dissolution and hydrogen induced cracking. The mechanism of common stress corrosion is: under the action of stress and corrosive medium, the oxide film on the surface of the part or component is corroded and damaged, the damaged surface and the undamaged surface form an anode and a cathode respectively, the metal at the anode becomes ions and is dissolved, and current flows to the cathode. Since the anode area is much smaller than the cathode, the current density of the anode is large, further corroding the damaged surface. And under the action of tensile stress, cracks are gradually formed at the damaged part, and gradually expand along with time until the fracture. Such cracks can develop not only along the metal grain boundaries, but also through the grains.
