Methods For Phase Diagram Determination

Phase diagrams are "maps" materials scientists often use to design new materials. They define what compounds and solutions are formed and their respective compositions and amounts when several elements are mixed together under a certain temperature and pressure. This monograph is the most comprehensive reference book on experimental methods for phase diagram determination. It covers a wide range of methods that have been used to determine phase diagrams of metals, ceramics, slags, and hydrides. * Extensive discussion on methodologies of experimental measurements and data assessments * Written by experts around the world, covering both traditional and combinatorial methodologies* A must-read for experimental measurements of phase diagrams

This collection of papers is from Materials Week '93 held in Pittsburgh, Pennsylvania, October 17-21, 1993. Phase diagrams are a construction of phase equilibria data that have applications in both science and technology. The diagrams are available in handbooks for most binary and selected ternary systems and have long been used by materials engineers in alloy and process design. Diagrams for higher order systems are not normally available, which requires engineers to infer the behaviour of complex industrial systems.

This well-written text is for non-metallurgists and anyone seeking a quick refresher on an essential tool of modern metallurgy. The basic principles, construction, interpretation, and use of alloy phase diagrams are clearly described with ample illustrations for all important liquid and solid reactions. Gas-metal reactions, important in metals processing and in-service corrosion, also are discussed. Get the basics on how phase diagrams help predict and interpret the changes in the structure of alloys.

Studies in Modern Thermodynamics, 3: Phase Theory: The Thermodynamics of Heterogeneous Equilibria focuses on the processes, methodologies, principles, and approaches employed in the determination of the thermodynamics of heterogeneous equilibria. The publication first elaborates on thermodynamic background, phase rule, and general relations for binary equilibria. Discussions focus on linear contributions, G-curves and phase diagram, function changes, Clapeyron's equation, derivation of phase rule, pressure and temperature, heat capacity, enthalpy, and Gibbs energy. The manuscript then examines demixing, isothermal liquid-vapor equilibria, isobaric equilibria between two mixed states, and isobaric equilibria between unmixed solid and mixed liquid state. Topics include phase diagrams, pure solid component with liquid mixture, equilibrium between two ideal states, calculation of phase diagrams, and types of phase diagram. The text ponders on the interpretation of TX phase diagrams and retrograde equilibrium curves, including retrograde solubility, regions of demixing, excess parameters, and eutectic systems. The publication is a valuable reference for researchers wanting to dig deeper into the thermodynamics of heterogeneous equilibria.

Computational tools allow material scientists to model and analyze increasingly complicated systems to appreciate material behavior. Accurate use and interpretation however, requires a strong understanding of the thermodynamic principles that underpin phase equilibrium, transformation and state. This fully revised and updated edition covers the fundamentals of thermodynamics, with a view to modern computer applications. The theoretical basis of chemical equilibria and chemical changes is covered with an emphasis on the properties of phase diagrams. Starting with the basic principles, discussion moves to systems involving multiple phases. New chapters cover irreversible thermodynamics, extremum principles, and the thermodynamics of surfaces and interfaces. Theoretical descriptions of equilibrium conditions, the state of systems at equilibrium and the changes as equilibrium is reached, are all demonstrated graphically. With illustrative examples - many computer calculated - and worked examples, this textbook is an valuable resource for advanced undergraduates and graduate students in materials science and engineering.

The Boundary Theory of Phase Diagrams and Its Application -- Rules for Phase Diagram Construction with Phase Regions and Their Boundaries presents a novel theory of phase diagrams. Thoroughly revised on the basis of the Chinese edition and rigorously reviewed, this book inspects the general feature and structure of phase diagrams, and reveals that there exist actually two categories of boundaries. This innovative boundary theory has solved many difficulties in understanding phase diagrams, and also finds its application in constructing multi-component phase diagrams or in calculating high-pressure phase diagrams. Researchers and engineers as well as graduate students in the areas of chemistry, metallurgy and materials science will benefit from this book. Prof. Muyu Zhao was the recipient of the 1998 Prize for Progress in Science and Technology (for his work on the boundary theory of phase diagrams) awarded by the National Commission of Education, China, and many other prizes.

The proceedings of the NATO Advanced Study Institute on title], held in Rhodes, Greece, June-July 1992, comprise invited and contributed papers that focus on recent experimental, theoretical, and computational developments in the study of phase alloy transformations. The coverage is in three parts:

This monograph acts as a benchmark to current achievements in the field of Computer Coupling of Phase Diagrams and Thermochemistry, often called CALPHAD which is an acronym for Computer CALculation of PHAse Diagrams. It also acts as a guide to both the basic background of the subject area and the cutting edge of the topic, combining comprehensive discussions of the underlying physical principles of the CALPHAD method with detailed descriptions of their application to real complex multi-component materials. Approaches which combine both thermodynamic and kinetic models to interpret non-equilibrium phase transformations are also reviewed.
