Polycrystalline materials, both dense and porous, are traditionally fabricated from ceramic, metal or composite powders via powder technology routes that include shaping and sintering steps. During shaping a compact body is formed from the granular raw material, while sintering leads to strengthening of this compact and coarsening. In this collection, the authors summarize the basic concepts and classical models used for describing solid state sintering processes. Following a brief introduction, in the second section a historical overview of early sintering theory is given, followed in the third section by an explanation of the driving force of solid state sintering. Following this, grain boundary is analyzed to discern how the spatial orientation of grains themselves may be defined generally and exactly. Additionally, one can easily understand that there is a correlation between the change in the grain orientation and grain deformation and this correlation was mathematically demonstrated. Finally, the authors interpret the quantity of grain orientation corresponding with the experimental measured value, the analysis of local deformation could be performed experimentally on the basis of their results. In closing, following an outline describing the historical development of ECAS and related techniques, the principle of ECAS is briefly described, current opinions concerning sintering mechanisms are summarized, and the problem of carbon contamination is discussed in some detail.

This book presents a physical approach to the diffraction phenomenon and its applications in materials science. An historical background to the discovery of X-ray diffraction is first outlined. Next, Part 1 gives a description of the physical phenomenon of X-ray diffraction on perfect and imperfect crystals. Part 2 then provides a detailed analysis of the instruments used for the characterization of powdered materials or thin films. The description of the processing of measured signals and their results is also covered, as are recent developments relating to quantitative microstructural analysis of powders or epitaxial thin films on the basis of X-ray diffraction. Given the comprehensive coverage offered by this title, anyone involved in the field of X-ray diffraction and its applications will find this of great use.

The book is best used in the following sequence. (1) The radiation and method of recording are selected in accordance with the data of Chapters 1 and 2; the detailed param eters for the recording are defined. (2) The patterns are indexed with the assistance of the graphs and tables of Chapter 3. (3) The measured intensities are compared with the values found from the tables of Chapter 4. (4) The particular problem at hand (determi nation of stresses, phase analysis, and so on) is solved with the aid of the tables and nomo grams given in the second part of the book. The nomograms can be enlarged for use if necessary. This is not the only mode of use; in particular, the material in the appropriate chapter may be sufficient for a particular type of routine analysis. I have had the benefit of valuable advice from workers in various laboratories (Moscow State University, Moscow Steel Institute, the Institute of Crystallography, the Central Research Institute for Ferrous Metallurgy, the Technological Research Institute of the Automobile Industry, the Karpov Institute of Physical Chemistry, the All-Union Hard Alloys K~search Institute, and so on). In addition, I am deeply indebted for much assistance to Professor Ya. S. Umanskii (scientific editor), Professor V. I. Iveronova, Professor A. I. Kitaigorodskii, G. A. Gol'der, and V. I. Rydnik. I recognize that this work cannot be free from deficiencies, and I should like to thank in advance workers in x-ray laboratories who may offer criticisms.

This practical book shows how an understanding of structure, thermodynamics, and electrical properties can explain some of the choices of materials used in microelectronics, and can assist in the design of new materials for specific applications. It emphasizes the importance of the phase chemistry of semiconductor and metal systems for ensuring the long-term stability of new devices. The book discusses single-crystal and polycrystalline silicon, aluminium- and gold-based metallisation schemes, packaging semiconductor devices, failure analysis, and the suitability of various materials for optoelectronic devices and solar cells. It has been designed for senior undergraduates, graduates, and researchers in physics, electronic engineering, and materials science.

In an attempt to meet the demand for new ultra-high strength materials, the processing of novel material configurations with unique microstructure is being explored in systems which are further and further from equilibrium. One such class of emerging materials is the so-called nanophased or nanostructured materials. This class of materials includes metals and alloys, ceramics, and polymers characterized by controlled ultra-fine microstructural features in the form oflayered, fibrous, or phase and grain distribution. While it is clear that these materials are in an early stage of development, there is now a sufficient body of literature to fuel discussion of how the mechanical properties and deformation behavior can be controlled through control of the microstructure. This NATO-Advanced Study Institute was convened in order to assess our current state of knowledge in the field of mechanical properties and deformation behavior in materials with ultra fine microstructure, to identify opportunities and needs for further research, and to identify the potential for technological applications. The Institute was the first international scientific meeting devoted to a discussion on the mechanical properties and deformation behavior of materials having grain sizes down to a few nanometers. Included in these discussions were the topics of superplasticity, tribology, and the supermodulus effect. Lectures were also presented which covered a variety of other themes including synthesis, characterization, thermodynamic stability, and general physical properties.

After a brief introduction into crystal plasticity,the fun- damentals of crystallographic textures and plastic anisotro- py, a main topic of this book, are outlined. A large chapter is devoted to formability testing both for bulk metal and sheet metal forming. For the first time testing methods for plastic anisotropy of round bars and tubes are included. A profound survey is given of literature about yield criteria for anisotropic materials up to most recent developments and the calculation of forming limits of anisotropic sheet me- tal. Other chapters are concerned with properties of workpieces after metal forming as well as the fundamentals of the theory of plasticity and finite element simulation of metal forming processes. The book is completed by a collection of tables of international standards for formability testing and of flow curves of metals which are most commonly used in metal forming. It is addressed both to university and industrial readers.
