This book was released on 1987 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a theoretical and experimental study of the effect of ion irradiation on phase stability in austenitic Ni-C and Fe-Ni-C alloys are presented. Calculations modeling the precipitation of graphite or cementite from Ni-C or Fe-Ni-C alloys indicate that irradiation may induce precipitation of either phase in alloys that are thermally undersaturated in carbon. Graphite precipitation occurred readily in supersaturated thermally aged specimens. Although the theoretical calculations predict that rapid graphite nucleation may occur in a range of undersaturated and supersaturated alloys as a result of 4-MeV Ni2+ ion irradiation, transmission electron microscopy (TEM) studies reveal no indication of such precipitation. The irradiated alloys remained single phase even for one time-temperature cycle, which produced the beginning of graphite precipitation under purely thermal aging. We conclude that a trapping mechanism involving the redistribution of carbon from solid solution to radiation-induced dislocation loops, voids, and other traps, perhaps via a solute drag effect, operates in such a manner as to suppress the precipitation promoted by irradiation induced vacancies. The results of this study have important implications on the radiation stability of austenitic steels that lack strong carbide formers.

Download or read book Phase Stability in Fe 15 Ni x Cr Alloys Under Ion Or Electron Irradiation written by JF. Stubbins and published by . This book was released on 1987 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three high-purity Fe-Ni-Cr alloys have been irradiated with heavy ions and with electrons at 450, 550, and 650°C to doses up to 60 dpa. The heavy ion irradiations were carried out with Ni6+ ions, and specimens were irradiated both with and without helium preinjection. The electron irradiations were carried out in a high-voltage electron microscope (HVEM) on specimens without helium preinjection. The alloy compositions were Fe-15 Ni-10 Cr, Fe-15 Ni-16 Cr, and Fe-15 Ni-20 Cr, all with low carbon levels. The latter two of these compositions are austenitic at room temperature, whereas the first can include martensite on rapid cooling. According to the computer calculated phase diagrams of Watkins et al, all of these alloy compositions would be metastable at the lowest irradiation temperature in the present study, but the austenitic phase structure should be stable in all of the alloys at the highest irradiation temperature.

Book excerpt: Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field
