Available in PDF, EPUB and Kindle. Book excerpt: 15Kh2MFA-type steel forgings were irradiated in an accelerated surveillance position of a power reactor, up to about 1 x 1021n/cm2, E > 1 MeV with medium flux. This steel is a Cr-Mo-V-type low-copper reactor pressure vessel material. 15Kh2MFA was microstructurally tested as received and in three different irradiation states within the frame of the LONGLIFE project. The following microstructural tests were performed: metallography, fractography, transmission electron microscopy, small angle neutron scattering, and atom-probe tomography. The aim of the current paper is to summarize the results that were evaluated by the six European institutes performing the study. The SANS tests show that the cluster volume fraction growth is nearly linear as a function of the fluence, and atom-probe tomography concludes that vanadium carbide precipitations were already originally present in the as-received steel. During irradiation these precipitates are enriched with Mo, Cu, and Cr. At the highest dose Mn, Si, and Ni are also attached to these clusters.

Download or read book Microstructural Processes in Irradiated Materials written by Steven J. Zinkle and published by Cambridge University Press. This book was released on 2014-06-05 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation can produce dramatic improvements or degradation in the properties of materials, so an understanding of the microstructural changes that occur during irradiation is critical for the development of predictive models. This book, first published in 2001, brings together researchers working on different materials systems so that similarities and differences in radiation effects can be compared. More specifically, it focuses on the microstructural changes which occur in solids during irradiation with ions, electrons, neutrons, gamma rays and X-rays. Materials of interest include metals, intermetallics, semiconductors, insulators and superconductors. Papers from a joint session on 'Multiscale Modelling of Materials' as well as experimental and theoretical studies are also included. Topics include: semiconductors; fundamentals of radiation effects in electronic materials, ceramics and polymers; ceramics and nuclear waste materials; austenitic and reactor pressure vessel steels; fundamental aspects of defect production and microstructure evolution in metals; and modelling radiation effects in metals.

Available in PDF, EPUB and Kindle. Book excerpt: Maintaining the integrity of nuclear power plants is critical in the prevention or control of severe accidents. This monograph deals with both basic groups of structural materials used in the design of light-water nuclear reactors, making the primary safety barriers of NPPs. Emphasis is placed on materials used in VVER-type nuclear reactors: Cr-Mo-V and Cr-Ni-Mo-V steel for RPV and Zr-Nb alloys for fuel element cladding. The book is divided into 7 main chapters, with the exception of the opening one and the chapter providing a phenomenological background for the subject of radiation damage. Chapters 3-6 are devoted to RPV steels and chapters 7-9 to zirconium alloys, analysing their radiation damage structure, changes of mechanical properties due to neutron irradiation as well as factors influencing the degree of their performance degradation. The recovery of damaged materials is also discussed. Considerable attention is paid to a comparison of VVER-type and western-type light-water materials. This monograph will be of great value to postgraduate students in nuclear engineering and materials science, and for designers and research workers in nuclear energy.

This book was released on 2017 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic domain structures are strongly influenced by material microstructures including crystal structures and defects. Correlations via microstructure between mechanical properties of steels and their magnetic properties invites the use of magnetic techniques to assess their microstructure. The vision of this work is to correlate magnetic characterizations and computational modeling to simulate progression of microstructural changes and predict resulting magnetic signatures in nuclear reactor structural steels using magnetic non-destructive evaluation (NDE) measurements.

This book was released on 2013-11-11 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Material science is one of the most evolving fields of human activities. Invention and consequent introduction of new materials for practical and/or technological purposes requires as complete knowledge of the physical, chemical, and structural properties as possible to ensure proper and optimal usage of their new features. In order to understand the macroscopic behaviour, one has to search for their origin on a microscopic level. A good deal of microscopic information can be obtained through hyperfine interactions. Mossbauer spectroscopy offers a unique possibility for hyperfine interaction studies via probing the nearest order of resonant atoms. Materials which contain the respective isotope as one of the constituent elements (e.g., iron, tin, ... ) but also those which even do not contain them can be investigated. In the latter case, the probe atoms are incorporated into the material of interest in minor quantities (ca. 0.1 at. %) to act as probes on a nuclear level. This Workshop has covered the most evolving topics in the field of Mossbauer spectroscopy applied to materials science. During four working days, SO participants from 19 countries discussed the following areas: Chemisliy, Mineralogy and Metallurgy, Artificia/~y Structured Materials, Nanosized Materials and Quasicrvstals. and Experimental Techniques and Data Processing. A total of 42 contributions (30 keynote talks) reviewed the current state of art of the method, its applications for technical purposes, as well as trends and perspectives. A total of 39 papers are included in the present volume. Applications in Chemisfr\'.
