Abstract

A double overlapping etch zone technique for evaluation of the resistance of metallic alloys to stress corrosion cracking is described. The technique involves evaluating the metallic alloy along the line of demarcation between an overlapping double etch zone and single etch zone formed on the metallic alloy surface.

Technique for measuring stress corrosion cracking of metallic electrodes in aqueous solutions

Journal Article Habib, K. (Kuwait Inst. for Scientific Research, Safat (Kuwait)); Carmichael, G.; Lakes, R.; ... - Corrosion (Houston); (United States)

A mathematical model relating deformation to electrochemical behaviors of metals in aqueous solution has been developed. The model was established based upon principles of holographic interferometry for measuring microscopic deformation and of electrochemistry for measuring the corrosion of metals, i.e., anodic dissolution current. The model can be used to calculate the stress corrosion of metals under a constant load or displacement in a polarized or unpolarized condition. The current density of metals can be calculated as a function of imposed deformations. The model was used to calculate the stress corrosion behavior of a nickel electrode under a constant load inmore »« less

Mechanical nature of stress-corrosion cracking in Al--Zn--Mg alloys. I Evaluation of the ductile rupture contribution

Journal Article Wood, W.E.; Gerberich, W.W. - Metall. Trans.; (United States)

A detailed study of rapid stress-corrosion-cracking (SCC) in a 7075 aluminum alloy has allowed separation of the mechanical and chemical contributions. This was accomplished by combining scanning electron microscopy, stress-wave emission and crack growth rate observations as a function of test temperature. These established an activation energy of 11.2 kcal/mol, a stress-intensity squared dependence of crack growth, and a range of 20 to 80 pct dimpled rupture on the fracture surfaces. Thus a two-step crack growth mechanism is proposed combining a thermally activated electrochemical process and a discontinuous mechanical jumping process.

Etch pitting and stress-corrosion cracking of copper

Journal Article Sieradzki, K. (Johns Hopkins Univ., Baltimore, MD (United States). Dept. of Materials Science and Engineering); Kim, J.S. (Korea Advanced Energy Research Inst., Nuclear Fuel Material Research Dept., P.O. Box 7, Daedukdanji, Chungnam (KR)) - Acta Metallurgica; (United States)

This paper presents evidence that an elemental metal can undergo stress-corrosion cracking by an anodic dissolution process under nominally film-free or active dissolution conditions. Oriented cooper single crystal samples tested at high strain rates in non-tarnishing cupric ammonia solutions undergo severe stress-corrosion cracking. The occurrence of stress-corrosion cracking in these samples is correlated with the development of uniform microscopic porosity which develops owing to the spectacular effect that dynamic straining has on the etch pitting process. The porous surface morphology and the cracking obtains when there is a certain balance between the rate of corrosive attach which is manifested asmore »« less
