100 years after the first observation of ripening by Ostwald and 40 years after the first publication of a theory describing this process, this monograph presents in a self-consistent and comprehensive manner, all the bits and pieces of coarsening theories so that the main issues and the underlying mathematics of self-similar coarsening of dispersed systems can be understood. Rather than giving a complete survey of the field, it presents a careful derivation of the existing results and places them into some perspective.

The annealing of deformed materials is of both technological importance and scientific interest. The phenomena have been most widely studied in metals, although they occur in all crystalline materials such as the natural deformation of rocks and the processing of technical ceramics. Research is mainly driven by the requirements of industry, and where appropriate, the book discusses the extent to which we are able to formulate quantitative, physically-based models which can be applied to metal-forming processes.The subjects treated in this book are all active research areas, and form a major part of at least four regular international conference series. However, there have only been two monographs published in recent times on the subject of recrystallization, the latest nearly 20 years ago. Since that time, considerable advances have been made, both in our understanding of the subject and in the techniques available to the researcher.The book covers recovery, recrystallization and grain growth in depth including specific chapters on ordered materials, two-phase alloys, annealing textures and annealing during and after hot working. Also contained are treatments of the deformed state and the structure and mobility of grain boundaries, technologically important examples and a chapter on computer simulation and modelling. The book provides a scientific treatment of the subject for researchers or students in Materials Science, Metallurgy and related disciplines, who require a more detailed coverage than is found in textbooks on physical metallurgy, and a more coherent treatment than will be found in the many conference proceedings and review articles.

Crystal growth far from thermodynamic equilibrium is nothing but homoepitaxy - thin film growth on a crystalline substrate of the same material. Because of the absence of misfit effects, homoepitaxy is an ideal playground to study growth kinetics in its pure form. Despite its conceptual simplicity, homoepitaxy gives rise to a wide range of patterns. This book explains the formation of such patterns in terms of elementary atomic processes, using the well-studied Pt/Pt(111) system as a reference point and a large number of Scanning Tunneling Microscopy images for visualization. Topics include surface diffusion, nucleation theory, island shapes, mound formation and coarsening, and layer-by-layer growth. A separate chapter is dedicated to describing the main experimental and theoretical methods.

This volume contains the papers presented at the NATO Advanced Research Workshop on "Kinetics of Ordering and Growth at Surfaces", held in Acquafredda di Maratea, Italy, September 18-22, 1989. The workshop's goal was to bring together theorists and experimentalists from two related fields, surface science and thin-film growth, to highlight their common interests and overcome a lack of communication between these two communities. Typically surface scientists are only concerned with the microscopic (atomic) description of solids within one monolayer of the surface. Thin-film growers are usually considered more empirical in their approach, concerned primarily with the "quality of their product", and have not necessarily found it useful to incorporate surface science understanding into their art. This workshop aimed to counter at least in some measure these stereotypes. Its focus was on generating dialogue on the fundamental structural and kinetic processes that lead to the initial stages of film growth, from both the surface science and crystal growth perspectives. To achieve this, alternate days emphasized the view of surface science and thin-film growth, with considerable time for discussion, a format that appeared to succeed well. The success of the workshop is in large measure due to the efforts of the organizing committee, L. C. Feldman, P. K. Larsen, J. A. Venables, and J. Villain, whose advice on the constitution of the program was invaluable.

Decomposition of Alloys: The Early Stages contains the proceedings of the 2nd Acta-Scripta Metallurgica Conference held in Sonnenberg, Germany, on September 19-23, 1983. Contributors discuss the early stages of decomposition in alloys, placing emphasis on the unsolved problems of the field, rather than on the solved ones. This book has 36 chapters and opens with a discussion on developments in the theory of the kinetics of first-order phase transitions, followed by an analysis of metastability and spinodal nucleation; neutron scattering during decomposition of aluminum alloys; Ostwald ripening of precipitates; and phase stability under irradiation. The next chapters explore decomposition processes in Al-Zn alloys; thermal decomposition in Cu-Ni-Fe alloys; and the initial stages of discontinuous precipitation reactions. Other papers focus on the mechanisms of plate precipitate growth; spinodal decomposition and continuous ordering; and early stages of decomposition in Ni-Al single crystals. This monograph will be of interest to students and practitioners of physics and metallurgy.

The behavior of adjacent materials at the boundary where they meet is an essential aspect of creating new engineering materials. Grain Boundary Migration in Metals is an authoritative account of the physics of grain boundary motion, written by two highly respected researchers. They provide a comprehensive overview of current knowledge regarding the migration process and how it affects microstructure evolution, focusing their treatment exclusively on the properties and behavior of grain boundaries with well defined geometry and crystallography. With their emphasis on applications-such as the characterization of microstructure and texture, recrystallization, and grain growth-the authors effectively fill the gap between the physics of grain boundary motion and its engineering practicality. The need for better microstructural design motivates permanent thrust for research in the field, and continued rapid progress appears inevitable. Grain Boundary Migration in Metals provides a solid foundation in the phenomena and serves as a valuable reference for professionals in materials science, solid state physics, and any industry engaged in metals production and the heat treatment of metals and alloys.

Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceuticals, paints and oil industries. As end products, emulsions allow to avoid organic solvent in processing hydrophobic coatings. Emulsion technology is a suitable approach to vehicle viscous phases. It is also a remarkable mean of targeting actives or capturing specific species. The range of applications of emulsions progresses and their manufacturing becomes more and more sophisticated. Besides this broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physic and chem istry. Indeed, as a class of soft colloidal materials, emulsions science is linked to various aspects of these disciplines: phase transitions, surface forces and wetting, metastability and hydrodynamic instabilities, mechanical properties and flow. The aim of this book is to review the main important concepts governing emulsion science. In Chapter 2, repulsive interactions between liquid films are discussed as well as adhesive interaction related to wetting. In Chap ter 3, consequences of weak and strong attractions are presented, related to the well accepted liquid solid transition analogy. In Chapter 4, the basics of both bulk compressibility and shear elasticity are presented, the role of disorder being the most important aspect of the elastic behavior of these soft systems. In Chapter 5 the central question of the emulsion lifetime related to metastability is discussed.
