Stress-Corrosion Cracking: the Importance of Damage Evolution in the Layer Affected by Corrosion
Abstract
In Stress Corrosion Cracking (SCC), [a determining factor for cracks propagating from corrosion sites, and possibly leading to catastrophic failure of the material], is the structure of the damaged region near the surface or the corrosion site. This is because in the corroded region, damage creates weak spots, embrittlement, and heterogeneities in the material’s strength and elasticity from where cracks can develop, thus leading to potential for unstable crack growth and material failure. The evolution of mechano-chemical properties in the corrosion-affected layer is currently unknown. They propose to investigate these properties and their evolution in stress corrosion cracking with the goal of predicting initiation and dynamic growth of cracks from corrosion sites.
