This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal reasons which induced the authors to write this book and the features of the book are set forth in the preface to the Russian edition. That section of the science of metals which in Russian is called "metallovedenie" or the "physical chemistry of metals" is generally referred to in scientific and technical literature published in the English language by the term "physical metallurgy." These concepts are much broader than the term" metallography," used in the scientific and technical literature of various countries, and applied solely to research on the interrelationships of the structure and proper ties of metals and alloys. Each science must have its own subject and its own method of research. Certainly, all specialists will agree that metals and alloys, including their solid solutions, mechanical mix tures, and metallic compounds, form the subject of "physical metallurgy" or "physical chemis try of metals." The aim of this science. is to produce a theory and to elucidate the experimental relationships which ought finally to make it possible to calculate quantitatively alloys Of given properties for any working conditions and parameters.

This book was released on 2012-12-06 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication documents Proceedings of the Symposium on Metal lurgy and Technology of Refractory Metal Alloys, held in Washington, D.C. at the Washington Hilton Hotel on April 25-26, 1968, under sponsorship of the Refractory Metals Committee, Institute of Metals Division, of the Metallurgical Society of AIME, and the National Aeronautics and Space Administration. The Symposium presented critical reviews of selected topics in refractory metal alloys, thereby contributing to an in-depth understanding of the state-of-the-art, and establishing a base line for further research, development, and application. This Symposium is fifth in a series of conferences on refractory metals, sponsored by the Metallurgical Society of AlME. Publications issuing from the conferences are valuable technical and historical source books, tracing the evolution of refractory metals from early laboratory alloying studies to their present status as useful engineering materials. Refractory metals are arbitrarily defined by melting point. A 0 melting temperature of over 3500 F was selected as the minimum for this Symposium, thus excluding chromium and vanadium, which logically could be treated with other refractory metals in Groups VA and VIA of the periodic table. The Refractory Metals Committee is planning reviews of chromium and vanadium in subsequent conferences.

This book was released on 1963 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the present knowledge concerning the relationship among fabrication history, metallurgical structure, and the mechanical properites of the refractory metals columbium, tantalum, bolybdenum, and tungsten, and their alloys. These are the refractory metals currently reveiveing the most attention for aerospace applications, and are therefore the materials considered in this survey. The report is organized into three main sections, titled ''Fabrication'', ''Microstructure and Alloying'', and ''Interstitial Impurities''. The data presented were selected as those which best illustrate the topics discussed. Descriptions of the metaljurgical principles involved are included. Suggestions for optimizing mechanical properties by controlling metallurgical structure are made where possible. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The transverse bend transition temperatures of a molybdenum alloy with carbon levels of 0.03, 0.07, and 0.10% are shown to be within the limits of -100 to +250 F. The sheet rolled directly from sheet bar to finished gage without intervening anneal generally possesses the lowest transition temperature. Differences in transition temperature between the cold worked and recrystallized structures are generally small. Laminating tendency is shown to be associated with the cold worked structure. With the advance of recrystallization it disappears. A condition of about 30% recrystallization corresponds to the disappearance of laminating tendency and a maximum in bend-rebend ductility.

Available in PDF, EPUB and Kindle. Book excerpt: The application of refractory metals encompasses areospace and nuclear industries, fusion energy, high energy physics, electonics, energy conversion and chemical processing. Metals belonging to groups Va and VI of the periodic table, which form the refractory metals family, are characterised by many common features. They have the same crystal structure (bcc), high melting points, similar chemical interactions with other elements, generally high ductile-brittle transition temperatures and a similar alloying behaviour. Because of these similarities, the metallurgy of these metals can be developed on a common foundation and handled in a unified manner. The common features of the chemical processing methods and physical and mechanical behaviours of this group of metals have never before been covered in a single book. The book will begin with an account of the interatomic bonding and physical properties of these metals. The different classes of phase diagrams that these metals exhibit and their interactions with interstitial elements will be summarized. The problem of high ductile-brittle transition temperatures and the general principles of ductilization will also be discussed. The book will bring out the fact that in the case of these metals different physical phenomena like deformation, diffusion, recovery, recrystallisation, creep and oxidation stand on a common ground and bear a create deal of similarity. Therefore the same principles can be applied for alloying, strengthening, ductilising and protecting these metals. The book will also cover recent developments in coating technology, intermetallics and composites related to refractory metals. This book is anup-to-date, single source account of physical and chemical metallurgy. It will be invaluable for undergraduate and graduate students, research workers and professionals in the field of high temperature metals and materials. A thorough summary of both the chemical and the physical metallurgy of the bcc refractory metals from a single, reliable source. Unifies the field of refractory metals.
