Stress-assisted corrosion
WebDuring his PhD, Aaron focused on researching the corrosion phenomena known as Irradiation Assisted Stress Corrosion Cracking (IASCC), which occurs when susceptible materials are placed under relevant stress conditions in a corrosive environment. He used Transmission Electron Microscopy (TEM) and Focused Ion Beam-Scanning Electron … WebStress corrosion (or stress-assisted corrosion) cracks are typically branched with numerous small secondary cracks associated with the main fracture area. Causes: It occurs where a combination of high-tensile stresses and a corrosive fluid are present. The damage results from cracks that propagate from the ID.
