Book Description
The use of thermodynamic databases permits the calculation of equilibrium phase diagrams of many important industrial systems. An assessed thermodynamic database based on the results of decades of conducting experiments and calorimetric measurements is at the core of all industrial and scientific enquiries. An internally consistent database is assessed (built) by using the thermochemical (calorimetric) data in producing the results of phase equilibrium experiments. The procedure is usually referred to as the Calphad method. In equilibrium calculations, the temperature and composition variables are standard but the inclusion of the important variable pressure requires more complicated models for equations of state. The latter require pressure–volume–temperature data on materials that are not so common. Similarly, while there is ample data on binary and some ternary solutions, the multicomponent and multisite models become very cumbersome to deal with. Existing thermodynamic data permit us to draw many interesting phase diagrams such as the binary silicides (Mn–Si, W–Si), and carbothermal reduction of silica and iron at extreme pressures. Many of the currently existing phase diagrams are not based on actual in situ crystal structures at the appropriate temperature or pressure. An example of Al–Fe is given.

Book Description
This textbook deals with the theoretical basis of chemical equilibria and chemical changes and emphasizes the properties of phase diagrams. The author treats the field from a modern perspective. He takes into account the dramatic changes in the methods of applying thermodynamics caused by the development both of computer operated programs for sophisticated equilibrium calculations and of extensive databases containing thermodynamic parameter values for individual phases from which all thermodynamic properties may be calculated. This new situation has inspired a new approach to the teaching of basic thermodynamics. Illustrative examples of thermodynamic modeling are also given, and the book contains many exercises and worked solutions. This modern text will be of value to undergraduate and graduate students in materials science and chemistry.

Book Description
J.-P. CALISTE, A. TRUYOL AND J. WESTBROOK The Series, "Data and Knowledge in a Changing World", exemplifies CODATA's primary purpose of collecting, from widely different fields, a wealth of information on efficient exploitation of data for progress in science and technology and making that information available to scientists and engineers. A separate and complementary CODATA Reference Series will present Directories of compiled and evaluated data and Glossaries of data-related terms. The present book "Thermodynamic Modeling and Materials Data Engineering" discusses thermodynamic, structural, systemic and heuristic approaches to the modeling of complex materials behavior in condensed phases, both fluids and solids, in order to evaluate their potential applications. Itwas inspired by the Symposium on "Materials and Structural Properties" held during the 14th International CODATA Conference in Chambery, France. The quality of the contributions to this Symposium motivated us to present" a coherent book of interest to the field. Updated contributions inspired by Symposium discussions and selections from other CODATA workshops concerning material properties data and Computer Aided Design combine to highlight the complexity of material data issues on experimental, theoretical and simulation levels Articles were selected for their pertinence in three areas. Complex data leading to interesting developments and tools such as: • new developments in state equations and their applications, • prediction and validation of physical and energy data by group correlations for pure compounds, • modeling and prediction of mixture properties.

Book Description
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.

Book Description
"The phase diagram and thermodynamic properties of the Al2O3-CaO-FeO-Fe2O3-MgO-MnO-Mn2O3-SiO2-Ti2O3-TiO2 system are important in various applications such as steelmaking, refractories, advanced ceramics, petrology and geochemistry. In the present work, the available thermodynamic database for the Al2O3-CaO-FeO-Fe2O3-MgO-SiO2 system was expanded toward the Mn and Ti oxide systems to develop an accurate thermodynamic database for the ten-component system. For this purpose, a complete literature review, critical evaluation and thermodynamic optimization of the phase diagrams and thermodynamic properties of related systems at 1 atm was performed. As part of the thermodynamic study, key phase diagram experiments were performed in the Fe-Ti-O, Mn-Ti-O, Al-Ti-O, Fe-Mn-Ti-O, Mg-Mn-Ti-O, Mn-Si-Ti-O, and Mn-Al-Ti-O systems in air to obtain unknown phase equilibria between the liquid phase and complex solid solutions and resolve any inconsistencies among existing experimental data in the literature.Phase diagram experiments were performed using the classical equilibration and quenching technique. Phase analysis was performed using Electron Probe Microanalysis (EPMA) and X-ray Diffraction (XRD) on all the quenched samples. In the Al-Ti-O system, the solubility of Al2O3 in the rutile (TiO2) solid solution was measured at high temperature. In the Fe-Ti-O system, the liquidus, solubility of Fe2O3 in the rutile (TiO2) solution, and the homogeneity ranges of Fe2O3-FeTiO3 ilmenite and Fe2TiO5-Ti3O5 pseudobrookite solutions were determined at high temperature. In the Mn-Ti-O system, the liquidus, MnO solubility in rutile and the homogeneity range of Mn3O4-Mn2TiO4 spinel were measured. In the Mg-Mn-Ti-O, Fe-Mn-Ti-O and Mn-Si-Ti-O systems, the complex phase equilibria between liquid and solid solutions were experimentally elucidated for the first time in air atmosphere. For the thermodynamic optimization, the liquid phase was described using the Modified Quasichemical Model considering short-range ordering in the molten oxide and the Gibbs energies of the complex solid solutions pseudobrookite, ilmenite and spinel were described using the Compound Energy Formalism considering the crystal structure of each solid solution. Using the thermodynamic models with optimized model parameters in binary and ternary systems, the phase diagrams and thermodynamic properties of higher order systems in the Al2O3-CaO-FeO-Fe2O3-MgO-MnO-Mn2O3-SiO2-Ti2O3-TiO2 system were well calculated. The database containing the optimized model parameters in this study is compatible with the other FactSage thermodynamic databases and can be used to calculate any unexplored phase diagram and thermodynamic properties within the ten-component system. The database can be used for the complex thermodynamic calculations applicable to pyrometallurgy and advanced ceramics and used for the optimization of industrial processes and the development of new materials.

Book Description
This advanced comprehensive textbook introduces the practical application of phase diagrams to the thermodynamics of materials consisting of several phases. It describes the fundamental physics and thermodynamics as well as experimental methods, treating all material classes: metals, glasses, ceramics, polymers, organic materials, aqueous solutions. With many application examples and realistic cases from chemistry and materials science, it is intended for students and researchers in chemistry, metallurgy, mineralogy, and materials science as well as in engineering and physics. The authors treat the nucleation of phase transitions, the production and stability of technologically important metastable phases, and metallic glasses. Also concisely presented are the thermodynamics and composition of polymer systems. This innovative text puts this powerful analytical approach into a readily understandable and practical context, perhaps for the first time.
