This book was released on 2000 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude est basée sur un cas de terrain d'un type de fissuration rencontré sur des aciers de canalisations enterrées sous protection cathodique. Notre travail s'est inscrit dans la recherche des paramètres qui ont favorisé le développement des fissures, ainsi que dans l'examen des possibilités d'atténuer le phénomène. En premier lieu, notre travail s'est axé sur l'étude des micro-mécanismes de fissuration (essais de traction lente et sous sollicitations dynamiques). Puis, nous nous sommes rapprochés de conditions de terrain, en étudiant les modes de rupture (essais sous sollicitations cycliques). Des éprouvettes lisses ou micro-entaillées, testées à potentiel libre ou cathodique, ont été utilisées. La fissuration trouve son origine dans une modification des propriétés des aciers par l'hydrogène. De tels effets ne peuvent se produire que si deux critères sont réunis : des conditions favorables aux entrées de l'hydrogène , et une localisation de l'hydrogène et de ses effets. Nous avons ainsi montré le rôle d'une déformation dynamique dans l'obtention d'une entrée significative d'hydrogène. A potentiel cathodique, les effets de l'hydrogène sont exacerbés par la présence de MnS qui conduisent à l'amorçage de fissures internes (HIC) et à un mode de rupture de type SOHIC. A potentiel libre, la plus faible quantité d'hydrogène disponible confère aux effets de localisation un rôle accru. La fissuration est alors à relier à un mécanisme de type CSC. La fissuration de service s'explique par la présence de cycles de pression, d'une surprotection cathodique et d'aciers sensibles. La protection cathodique apparaît comme le paramètre de terrain le plus efficace pour atténuer le phénomène de fissuration, via un meilleur contrôle du niveau de polarisation. Parallèlement, un test de classification des aciers vis à vis de leur sensibilité à la fissuration a pu être défini sur la base de la compréhension des mécanismes de fissuration.
Book Synopsis Nuclear Corrosion Science and Engineering by : Damien Feron
Download or read book Nuclear Corrosion Science and Engineering written by Damien Feron and published by Elsevier. This book was released on 2012-02-21 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of nuclear materials, i.e. the interaction between these materials and their environments, is a major issue for plant safety as well as for operation and economic competitiveness. Understanding these corrosion mechanisms, the systems and materials they affect, and the methods to accurately measure their incidence is of critical importance to the nuclear industry. Combining assessment techniques and analytical models into this understanding allows operators to predict the service life of corrosion-affected nuclear plant materials, and to apply the most appropriate maintenance and mitigation options to ensure safe long term operation. This book critically reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities. Initial sections introduce the complex field of nuclear corrosion science, with detailed chapters on the different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them. This is complemented by reviews of monitoring and control methodologies, as well as modelling and lifetime prediction approaches. Given that corrosion is an applied science, the final sections review corrosion issues across the range of current and next-generation nuclear reactors, and across such nuclear applications as fuel reprocessing facilities, radioactive waste storage and geological disposal systems. With its distinguished editor and international team of expert contributors, Nuclear corrosion science and engineering is an invaluable reference for nuclear metallurgists, materials scientists and engineers, as well as nuclear facility operators, regulators and consultants, and researchers and academics in this field. Comprehensively reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities Chapters assess different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them Considers monitoring and control methodologies, as well as modelling and lifetime prediction approaches

Book Synopsis Stress-corrosion Cracking of Aluminum Alloys by : F. H. Haynie
Download or read book Stress-corrosion Cracking of Aluminum Alloys written by F. H. Haynie and published by . This book was released on 1966 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with the stress-corrosion cracking of aluminum alloys, and it represents an effort by DMIC to expand on the information contained in DMIC Memorandum 202, 'Stress-Corrosion Cracking of Aluminum Alloys', dated February 15, 1965. DMIC Report 228 begins by presenting a comprehensive definition of stress-corrosion cracking. This is followed by sections dealing with (1) the historical development and growth in awareness of the problem, (2) the mechanisms involved, and (3) the theory of stress-corrosion cracking. A section on experimental techniques is presented. These techniques include test methods used to determine the susceptibility of alloys to stress-corrosion cracking, as well as more refined methods of studying the fundamental mechanisms of the problem. Different evaluation methods, applicable to obtaining the different objectives of stress-corrosion testing, are also presented. All of the foregoing serve as background to the sections on stress-corrosion-cracking behavior of aluminum alloys and preventive measures. (Author).

Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --

Committee on Filler Metals and Allied Materials and published by . This book was released on 2013-03-11 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This specification prescribes the requirements for the classification of over 30 titanium and titanium-alloy welding electrodes and rods. Classification is based on the chemical composition of the electrode. Major topics include general requirements, testing, packaging, and application guidelines. This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other. This specification adopts the requirements of ISO 24034 and incorporates the provisions of earlier versions of A5.16/A5.16M, allowing for classifications under both specifications.
