This book was released on 1960 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work reported is the result of an investigation of phase equilibria in the binary system, tungsten-carbon. A tentative phase diagram is presented which differs significantly from the one proposed by Sykes in 1930 and which is generally accepted today. The data were obtained by high-temperature differential thermal analysis and classical quenching procedures, both supplemented by metallographic, x-ray, and chemical techniques. Results for the tungsten-carbon binary system indicate a eutectic between W and W2C at 2735 C, and a eutectic between W5C3 and C at 2765 C. The W2C lattice accommodates 72 and 74 atomic per cent W at 2475 degrees and 2735 C, respectively. Carbon solubility is evident only at 2540 C, the eutectoid temperature. A new phase, W5C3, was discovered which is stable only above 2540 C. WC decomposes at 2730C into W5C3 and C.

Download or read book Lecture Notes on Equilibrium Point Defects and Thermophysical Properties of Metals written by Yaakov Kraftmakher and published by World Scientific. This book was released on 2000 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the significant progress in the study of point defects in metals, some important problems still do not have unambiguous solutions. One of the most practically important questions relates to equilibrium defect concentrations. There exist two opposite viewpoints: (1) defect contributions to physical properties of metals at high temperatures are small and cannot be separated from the effects of anharmonicity; the equilibrium defect concentrations at the melting points are in the range of 10(-4) to 10(-3); (2) in many cases, defect contributions to the specific heat of metals are much larger than nonlinear effects of anharmonicity and can be separated without crucial errors; the equilibrium concentrations at the melting points are of the order of 10(-3) in low-melting-point metals and 10(-2) in high-melting-point metals. This book discusses the experimental results and theoretical considerations favoring each claim. At present, the majority of the scientific community hold the first viewpoint. Regrettably, the data supporting the second viewpoint have never been displayed and discussed together, and the criticism of this viewpoint has never included a detailed analysis. Important arguments supporting this viewpoint have appeared in the last decade. It may turn out that just calorimetric determinations provide the most reliable values of equilibrium defect concentrations in metals. In this book, the main attention is paid to equilibrium point defects in metals and their relation to thermophysical properties of metals. Along with a discussion on experimental data and theoretical estimates now available, some approaches are proposed that seem to be most suitable for settling thequestion.

Download or read book Chemical Thermodynamics For Metals And Materials (With Cd-rom For Computer-aided Learning) written by Hae-geon Lee and published by World Scientific Publishing Company. This book was released on 1999-10-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of thermodynamic books claiming to be original in both presentation and approach have been published. However, thermodynamics is still a confusing subject for uninitiated students and an “easy-to-forget” one for graduate engineers. In order to solve these problems, this computer aided learning package — textbook and CD-ROM — takes a new approach.This package is unique and beneficial in that it simulates a classroom lecture: it actually writes important equations and concepts on a virtual board, underlines, draws circles, places ticks to emphasise important points, draws arrows to indicate relationships, uses colours for visual effect, erases some parts to write new lines, and even repeats some parts of the lesson to stress their importance. This realistic simulation is made possible by the employment of the multimedia capabilities of the modern-day computer. Readers are not just passively presented with thermodynamics, they can also interactively select and repeat any particular topic of interest as many times as they want. This flexibility allows readers to choose their own pace of presentation. This complementary set is in many important respects better than the books that are currently available on the subject.

This book was released on 2007-01-01 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: George Lai's 1990 book, High-Temperature Corrosion of Engineering Alloys, is recognized as authoritative and is frequently consulted and often cited by those in the industry. His new book, almost double in size with seven more chapters, addresses the new concerns, new technologies, and new materials available for those engaged in high-temperature applications. As we strive for energy efficiency, the realm of high-temperature environments is expanding and the need for information on high temperature materials applications was never greater. In addition to extensive expansion on most of the content of the original book, new topics include erosion and erosion-corrosion, low NOx combustion in coal-fired boilers, fluidized bed combustion, and the special demands of waste-to-energy boilers, waste incinerators, and black liquor recovery boilers in the pulp and paper industry. The corrosion induced by liquid metals is discussed and protection options are presented.

Download or read book Chemical Equilibria in Hot Air with Moisture, Salt, and Vaporized Metal Contaminants written by John Zinn and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes computations of thermodynamic equilibrium chemical species conentrations in hot (300-6000 K) air with and without moisture, salt, and metallic contaminants. The importance of the salt and metal vabors stems form the fact that small concentrations can lead to greatly enhanced levels of ionization. Estimated thermodynamic functions are tabulated for 46 different complex molecular and polyatomic ions, and these ions are included in the equilibrium computations. The thermodynamic parameters are used for generating reaction rate coefficients for otherwise uninvestigated reactions which are ther everses of known reactions.

Download or read book High Temperature Phase Equilibria and Phase Diagrams written by Chu-Kun Kuo and published by Elsevier. This book was released on 2017-10-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: High temperature phase equilibria studies play an increasingly important role in materials science and engineering. It is especially significant in the research into the properties of the material and the ways in which they can be improved. This is achieved by observing equilibrium and by examining the phase relationships at high temperature. The study of high temperature phase diagrams of nonmetallic systems began in the early 1900s when silica and mineral systems containing silica were focussed upon. Since then technical ceramics emerged and more emphasis has been placed on high temperature studies. This book covers many aspects, from the fundamentals of phase diagrams, experimental and computational methods, applications, to the results of research. It provides an excellent source of information for a range of scientists such as materials scientists, especially ceramicists, metallurgists, solid-state physicists and chemists, and mineralogists.

Download or read book Wettability at High Temperatures written by N. Eustathopoulos and published by Elsevier. This book was released on 1999-11-24 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to bring together current scientific understanding of wetting behaviour that has been gained from theoretical models and quantitative experimental observations. The materials considered are liquid metals or inorganic glasses in contact with solid metals or ceramics at temperatures of 200-2000oC. Wetting has been a significant scientific concern for the last two centuries and reference will be made to classical work by nineteenth century scientists such as Dupré, Laplace and Young that was validated by observations of the behaviour of chemically inert ambient temperature systems.In attempting to achieve the aims of the book, the text has been divided into ten Chapters that can be grouped into four stages of presentation. The first stage comprises two Chapters that review established and newly developed models for their relevance to wetting behaviour at high temperatures, including recent models that encompass the role of chemical reactions at the solid/liquid interfaces. Attention is paid both to equilibrium wetting behaviour (Chapter 1) and to the factors that control the approach to equilibrium (Chapter 2). Then follow Chapters concerned with experimental techniques for scientific measurement of the extent of wetting (Chapter 3) and with the surface energy data for both metals and non-metals that are essential for quantitative interpretation of wetting behaviour (Chapter 4). Descriptions of experimentally determined and quantified wetting behaviour are presented and interpreted in the third part comprising five Chapters dealing with the characteristics of metal/metal, metal/oxide, metal/non-oxide, metal/carbon and molten glass/solid systems. The book concludes with a Chapter commenting on the role of wetting behaviour in joining similar and dissimilar materials by liquid route techniques.

High Temperature Differential Thermal Analysis written by H. D. Heetderks and published by . This book was released on 1965 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high sensitivity differential thermal analysis apparatus, capable of operating to temperatures of 3600 C under controlled time-temperature conditions, is described. Measurements on binary and ternary carbide systems revealed a number of previously undetected phase reactions. Wth the exception of V2C, all subcarbides of the refractory transition metals undergo isothermal phase changes at high temperatures. The lower temperature stability limits of the high temperature phases in the systems Mo-C and W-C were determined. Similar to the corresponding system with oxygen, the a-modification of hafnium is stabilized to higher temperatures by carbon additions, while the alpha-beta- transformation in titanium and zirconium is affected to a moderate extent only. The application of DTA-techniques to the investigation of non-variant equilibria involving a liquid phase and to the study of reaction kinetics (disproportionation of solid solutions, reactions along non-equilibrium paths, reactions involving order-disorder phenomena) is discussed and examples are given.
