This book was released on 2006 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zircaloy-2 and Zircaloy-4 have been tested by the slow-strain-rate technique at ambient and elevated temperatures in an acidic environment relevant to the proposed geologic repository at the Yucca Mountain site. Tests were performed with and without cathodic and anodic applied potentials. The results of stress corrosion cracking testing without applied potentials indicate that the ductility of both alloys was enhanced in terms of percent elongation, percent reduction in area, failure strain, and the time-to-failure with increasing temperature indicating improved ductility. However, the magnitude of true failure stress was gradually reduced at higher testing temperatures. The application of anodic and cathodic controlled potentials during slow-strain-rate testing enhanced the cracking susceptibility of both alloys showing more pronounced effect at anodic applied potentials. The corrosion potential for both alloys, became more active at the elevated temperature. The morphology of failure at cathodic potentials was ductile, showing dimpled microstructure. However, transgranular brittle failure was observed with both alloys at anodic controlled potentials.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encompasses, but is not restricted to: fracture mechanics, fatigue, creep, materials, dynamics, environmental degradation, numerical methods, failure mechanisms and damage mechanics, interfacial fracture and nano-technology, structural analysis, surface behaviour and heart valves. The structures under consideration include: pressure vessels and piping, off-shore structures, gas installations and pipelines, chemical plants, aircraft, railways, bridges, plates and shells, electronic circuits, interfaces, nanotechnology, artificial organs, biomaterial prostheses, cast structures, mining... and more. Case studies will form an integral part of the work.

Available in PDF, EPUB and Kindle. Book excerpt: Longer-term stress corrosion cracking (SCC) experiments, described in the activity plan E-20-56, are well underway at LLNL to evaluate the SCC susceptibility of candidate corrosion-resistant inner container materials in a 90°oC acidic brine containing 5 weight percent (wt%) NaCl using fatigue-precracked wedge-loaded double-cantilever-beam (DCB) specimens. The results of a recent localized corrosion study have revealed that the propensity to pitting and crevice corrosion in susceptible alloys is characterized by "critical potentials" obtained from the cyclic potentiodynamic polarization (CPP) experiments described in the activity plan E-20-43/44. It is also well known that the tendency to SCC can be influenced by the electrochemical potential. But the role of electrochemistry in SCC has not been explored to a large extent. Therefore, the proposed activity is aimed at evaluating the SCC behavior of susceptible container materials under measured and/or controlled electrochemical potential in repository-relevant environments using DCB and slow-strain-rate (SSR) test specimens. The magnitude of the controlled potential will be selected based on the measured "critical potentials" obtained from the CPP experiment performed earlier in a similar environment. The resultant data will enable the mechanistic understanding of the cracking process in materials of interest under the synergistic influence of applied stress and corrosive medium, which will be utilized in developing and validating the SCC models for long-term performance assessment.
