Download or read book Assessment of Aged Piping Dissimilar Metal Weld Integrity ADIMEW written by and published by . This book was released on 2008 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the three-year ADIMEW project, which started in November 2000, was to contribute to the development and verification of analysis methods that describe the behaviour of cracked dissimilar metal welds (DMW). The complexity of the problem results from the prevailing mixed-mode loading conditions, the variation in material constitutive equations across the weld zone, and the presence of large residual stress fields. Under these circumstances, classic fracture mechanics concepts are difficult to apply. The project had the following technological and scientific aims:- Quantify the accuracy and conservatism of structural integrity procedures used by the nuclear industry in Europe to predict the behaviour and assess the safety of circumferential defects at the surface of dissimilar metal welds, - Perform a unique verification of the load-carrying capacity of an industrially representative cracked DMW under operating conditions in a large-scale structural test. To do this, a special assembly was prepared, with circumferential cracks introduced into the surface of a dissimilar metal weld between low-alloy steel and austenitic steel pipes with a diameter of 450 mm, - Rapidly disseminate the results for the benefit of operators, regulators and research organisations in Europe, in collaboration with the Network for Evaluating Structural Components (NESC). In order to reach these objectives, a large-scale nuclear DMW was tested and the different analytical methods available checked against the experimental results. Complementary innovative actions have been done on mixed-mode rupture, comparison of notch and crack toughness values. The ADIMEW project had an organisation similar to the one of the BIMET project with complementary objectives: larger diameter and higher temperature. The ADIMEW project followed on from the successful Fourth Framework Programme (FP4) BIMET project which had complementary objectives but considered smaller-diameter weld mock-ups tested at ambient rather than service temperature. The main focus of ADIMEW project was the performance of a single benchmark 4-point bend-pipe test, conducted on a nominal 16" piping assembly at 300 °C and containing a ferritic to stainless steel (A508-308/309SS-316SS) DMW. A notch-like defect was inserted at the ferritic steel/buttering layer interface, to simulate plant experience of damage at the worst-case location for a crack in such components. A second DMW mock-up was also manufactured for the experimental determination of welding residual stresses and for the generation of material property data for input to the analysis procedures. A range of analysis methodologies, including conventional flaw assessment methods, J approaches and local-approach methods have been applied to predict the critical load for initiation of the defect, the extent of crack growth, and the path followed by the crack through the weld up to the maximum load. Consideration has also been given to factors such as welding residual stresses, mixed-mode loading and constraint effects. The ADIMEW test was successfully executed in July 2003. The complete results of investigations of the test pieces were available in October 2003 and the post-test analysis was completed by December 2003.

Available in PDF, EPUB and Kindle. Book excerpt: During the last century, nuclear power has been established as a reliable source of energy in the major industrialised countries. It has recently enjoyed a revival in attention and research due to the environmental concerns surrounding current conventional energy sources. Issues of regulation and safety are at the forefront of all discussions involving nuclear power, and will govern its place in the future. The Future of Nuclear Power takes a technical and comprehensive look at the current and future status of nuclear power throughout the world. The 17 chapters are divided into two main sections: a review of all current generation plants, and concepts for new advanced reactor design and safety. The broad-ranging topics covered by this publication, coupled with the current revival of interest in nuclear energy, make it a timely reference for all nuclear scientists. - Reviews the issues surrounding the future operation of existing commercial nuclear plants - Several chapters dedicated to the extensive research programs in place concerning safe and reliable operation - Compares nuclear and non-nuclear options for energy needs in the future; evaluating the benefits and risks of both

This book was released on 2021-11-13 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joining Processes for Dissimilar and Advanced Materials describes how to overcome the many challenges involved in the joining of similar and dissimilar materials resulting from factors including different thermal coefficients and melting points. Traditional joining processes are ineffective with many newly developed materials. The ever-increasing industrial demands for production efficiency and high-performance materials are also pushing this technology forward. The resulting emergence of advanced micro- and nanoscale material joining technologies, have provided many solutions to these challenges. Drawing on the latest research, this book describes primary and secondary processes for the joining of advanced materials such as metals and alloys, intermetallics, ceramics, glasses, polymers, superalloys, electronic materials and composites in similar and dissimilar combinations. It also covers details of joint design, quality assurance, economics and service life of the product. - Provides valuable information on innovative joining technologies including induction heating of metals, ultrasonic heating, and laser heating at micro- and nanoscale levels - Describes the newly developed modelling, simulation and digitalization of the joining process - Includes a methodology for characterization of joints
Download or read book Hot Cracking Phenomena in Welds III written by John Lippold and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third in a series of compendiums devoted to the subject of weld hot cracking. It contains 22 papers presented at the 3rd International Hot Cracking Workshop in Columbus, Ohio USA in March 2010. In the context of this workshop, the term “hot cracking” refers to elevated temperature cracking associated with either the weld metal or heat-affected zone. These hot cracking phenomena include weld solidification cracking, HAZ and weld metal liquation cracking, and ductility-dip cracking. The book is divided into three major sections based on material type; specifically aluminum alloys, steels, and nickel-base alloys. Each of these sections begins with a keynote paper from prominent researchers in the field: Dr. Sindo Kou from the University of Wisconsin, Dr. Thomas Böllinghaus from BAM and the University of Magdeburg, and Dr. John DuPont from Lehigh University. The papers contained within include the latest insight into the mechanisms associated with hot cracking in these materials and methods to prevent cracking through material selection, process modification, or other means. The three Hot Cracking Phenomena in Welds compendiums combined contain a total of 64 papers and represent the best collection of papers on the topic of hot cracking ever assembled.
