Stress Corrosion Cracking (SCC) has proven to be one such example of conditions found in use in high voltage transmission line applications that leads to brittle fracture of polymer matrix composites. SCC has been proven to be the result of acid buildup on the lines due to corona discharges and water buildup.
"Stress Corrosion Cracking of Nuclear Transmutation The disposal of high-level radioactive waste poses a severe challenge to all nuclear power-generating nations. The transmutation of nuclear waste, which is used in Europe, has been proposed for use in the U.S. to eliminate long-lived actinides and fission products from spent nuclear fuel. This article presents the results of stress corrosion cracking studies performed in neutral and acidic
Dec 18, 2020 · Irradiation Assisted Stress Corrosion Cracking (IASCC) is a material degradation phenomenon affecting austenitic stainless steels used in nuclear Pressurized Water Reactors (PWR), leading to the initiation and propagation of intergranular cracks. Such phenomenon belongs to the broader class of InterGranular Stress Corrosion Cracking (IGSCC). A micromechanical analysis of
A phase field formulation for dissolution-driven stress Independently of the specific cracking mechanism, film-rupture is a necessary condition for localised damage in these conditions. Also, a potential rationale for pitting corrosion and stress corrosion cracking is the rupture of the film due to mechanical straining, followed by localised dissolution of the metal (Scully, 1980, Jivkov, 2004). Repassivation follows each local film rupture event, with the new film

This type of damage is common in aluminum and steels that come into contact with salt-water. Other commonalities are aircraft structures exposed to the elements, nuclear components, and welds, where stress corrosion cracking is a possibility. Intermittent exposure to even trace amounts of salt can rapidly accelerate fatigue cracking.
Corrosion Issues in the French High-Level Nuclear Waste (2017) Stress corrosion cracking in the context of deep geological nuclear disposal investigations on P235 and P265 steels. Corrosion Engineering, Science and Technology 52:sup1, 131-135. Online publication date:23-Aug-2017.
Delayed Cracking - an overview ScienceDirect TopicsThe greater the stress, the shorter the time before cracking is generated. 2. Whether stress corrosion cracking is generated is mainly dependent on the combination of corrosive media, metallics, temperature, and pH value. For instance, corrosive media that contain chlorion may cause the sudden stress corrosion cracking of 13Cr, super 13Cr, 22Cr
The stress corrosion cracking susceptibility of the alloy, before and after the DCT, in chloride solution was examined using slow strain rate test (SSRT) method at various strain rates. The results show that the subzero treatment increases the secondary noncoherent nanoparticles at the grain boundary, and this slight precipitation did not

Skogsberg, Stress Cracking and Crevice Corrosion Resistance of Pd-Enhanced Ti-38644 ium Alloy Products in Deep Sour Gas Well Environments (Paper presented at the 12th International Corrosion Congress, Houston, TX, September 1993).
Intergranular Stress Corrosion Cracking of Welded Steel - A = macroscopic IGSCC (>1mm deep), B = microscopic cracking (0.025-1.0mm), C = very shallow IGC (<0.025mm), G = general corrosion, N = no corrosion detected *solution acidified to pH = 3.3 with HCl Examination of the thermal cycles revealed that fairly high interpass temperatures, in the range 80-150°C, had been used, especially for the multi
Jul 19, 2013 · AbstractThe fracture of alloys in certain chemical environments at static stresses appreciably below those that would cause fracture in the absence of the specific environment, has been the subject of an increasing number of experimental investigations over the last decade. It would be impossible in the present context to review all the published papers, and a selection has therefore
Stress Corrosion Cracking & Brittle Fracture of 400 kV Corrosion occurred in a simultaneous process involving the existing mechanical load, creating a process of stress corrosion cracking in fibers. After a sufficient amount of fibers had fractured and enough resin had decomposed, the insulators FRP core was no longer able to withstand loads due to the lines weight and movement, leading to
Stress Corrosion Cracking:Theory and Practice V.S. Raja Stress corrosion cracking (SCC) causes sudden failure of metals and other materials subjected to stress in a corrosive environment, especially at elevated temperatures. The problem affects industries such as petrochemical and nuclear power production. This book is divided into three parts looking at the mechanisms of stress corrosion cracking

Stress corrosion cracking susceptibility of P285NH and API The present work is based on stress corrosion cracking (SCC) tests to study the crack initiation sensitivity of carbon steels selected as the reference materials for the metallic parts in the multiba
Types of Corrosion Materials Selection Guide SwagelokSour gas cracking, also known as sulfide stress cracking (SSC), is the deterioration of metal due to contact with hydrogen sulfide (H 2 S) and moisture. H 2 S becomes severely corrosive in the presence of water. This condition can lead to embrittlement of the material, resulting in cracking under the combined action of tensile stress and corrosion.
