Effects of irradiation on intergranular stress corrosion

Intergranular stress corrosion cracking &YSCC) is a pervasive and generic problem in current light water reactor and advanced reactor designs that can lead to widespread component failure. IASCC is believed to be due to either to changes in the grain boundary composition, the microstructure or the water chemistry and corrosion potential. Electrochemistry of stress corrosion cracking of brassstress corrosion cracking (SCC) of various forms of brass. SCC was called "season cracking" because of Its resemblance In appearance to the cracking of wood during seasoning; however, this term Is misleading since SCC is a result of internal strains localized in effect by cor­

Film-rupture mechanism of stress corrosion

Stress-corrosion cracking may be either intercrystalline, as in aluminum alloys, alpha brass, and low-alloy steels, or transcrystalline, as is usually the case in magnesium-base alloys and the austeni tic stainless steels. It is agreed by most workers in the field that some degree of stress-corrosion cracking can be produced Induced Stress Corrosion Cracking of Austenitic Stainless NUREG/eR-7030, "Atmospheric Stress Corrosion Cracking Susceptibility of Welded and Unwelded 304, 304L, and 316L Austenitic Stainless Steels Commonly Used for Dry Storage Containers Exposed to Marine Environments," USNRC, October 2010. 3.

  • AbstractIntroductionPhase I Experimental ProgrammePhase I Results and DiscussionPhase II Experimental ProgrammePhase II ResultsSupermartensitic stainless steels (SMSS), including both lean grades (without molybdenum) and high grades (with 2% molybdenum), have shown sensitivity to intergranular corrosion or stress corrosion cracking (IGSCC) in weld HAZs during laboratory testing in chloride solutions acidified with CO 2 at above about 100°C. [1-9] Also, lean SMSS grades have cracked in service when exposed to hot acidic brines.

Constant-load and slow-strain-rate (SSR) testing techniques were used to evaluate the SCC and HE behavior of this alloy by using smooth and notched tensile specimens.

    of Stress Corrosion Cracking Via Laser Shock Peening Stress corrosion cracking is a phenomenon that can lead to sudden failure of metallic components. Here, we use laser shock peening (LSP) as a surface treatment for mitiga-tion of stress corrosion cracking (SCC), and explore how the material differences of 304 NACE TM0316-2016 - Technical Standards PDF DownloadThis document provides guidelines for the use of four-point bend testing to evaluate the resistance of metals, including carbon steel, low alloy steels and corrosion resistant alloys (CRAs), to stress corrosion cracking and sulfide stress cracking. The emphasis in this document is on the methodology of the four-point bend test. The context of the test [] STREESCORROSION CRACKING OF BRASS Emerald InsightStresscorrosion cracking has been a problem in the production of wroughtbrass articles for many years. During spinning or deep drawing of brass cups, lamp bases and the like, stresses are set up which remain in the metal unless removed by annealing. Then, if the brass is stored in an atmosphere containing small amounts of ammonia and water vapour, stresscorrosion cracking may occur.

    stress corrosion cracking of stainless steel shows estimated crack growth rate of up to 0.91 mm (0.036 inch) per year for cold metal Hotter metal, such as spent fuel dry storage canisters, will have increased crack growth rate, although initiation of the crack may take longer.Stress Corrosion Behavior of X65 Steel Welded Joint in The short-term stress corrosion cracking (SCC) behavior of X65 pipeline steel welded joints in simulated deep (1000 m) and shallow sea was studied by the immersion of U-shaped bend samples, electrochemistry, and scanning electron microscope observation of fracture surfaces.
