This volume contains the proceedings of Symposium F, "Nanophase and Nanocomposite Materials III," held November 29-December 2, at the 1999 MRS Fall Meeting in Boston, Massachusetts. This symposium is the third one of this series which began at the 1992 MRS Fall Meeting. The objective of this third symposium was to provide a forum to review the recent advances in nanophase and nanocomposite materials and to address the future prospects for these materials. Scientists from many parts of the world participated to present and discuss synthesis, processing, properties and applications of nanophase and nanocomposite materials. A total of about 240 papers from 23 countries were presented from academic institutions, government research organizations, and private industries. The 107 papers published in this proceedings have been refereed and presented as nine chapters.

One of the goals of materials science is to design alloys with pre-specified desirable technological properties. To achieve this goal, it is necessary to have a thorough understanding of the fundamental mechanisms underlying materials behavior. In particular, one must understand the effects on alloy properties caused by intentional changes in concentration and how the combinations of temperature, time and uncontrollable foreign impurities affect microstructure. In addition to the equilibrium phase information contained in phase diagrams, nonequilibrium dynamic processes and metastable phases are known to be crucial in determining materials properties. This volume brings together researchers working on various aspects of nonequilibrium processes in materials to discuss current research issues and to provide guidelines for future work. Particular attention was paid to understanding particle nucleation and growth, both experimentally and theoretically, solid-state reactions, nanosystems, liquid-solid transformations, and solidification and amorphization. On the theoretical side, fundamental principles governing nucleation and growth, and related phenomena such as coarsening and Ostwald ripening, are discussed. Progress is also reported on the phase field method and on Monte Carlo simulations.

Epitaxial growth has always been a marriage of convenience between film and substrate. More and more frequently, however, it is impractical to use the same material for both film and substrate because it is not available as large single crystals, it is prohibitively expensive, or its properties are ill-suited for the intended application. To meet these challenges, many strategies have been pursued to achieve highly oriented or single-crystal thin films via epitaxy. Crystalline films have been mechanically bonded to other materials to form composite substrates. Crystals have been cut and rewelded, patterned and regrown, buffer layered and repolished. Each strategy has met with fundamental challenges including lattice mismatch, chemical incompatibility, differences in thermal expansion, and structural dissimilarity. This book, first published in 2000, focuses on developments in novel substrate engineering which enable improved epitaxy. Topics include: biaxially textured substrates for high-Tc-coated conductors; surfaces for oxide epitaxy; wafer bonding and lift off; lattice mismatch engineering; substrate engineering and solid-phase recrystallization and epitaxy.

This volume, the fifth in a popular series, features papers related to the development and utilization of materials with novel electrical, optical or magnetic properties. The field has experienced tremendous growth in the past years, and this volume provides a forum for materials scientists, chemists, physicists and engineers to assess the progress. In particular, light-emitting materials for displays are showing great promise for widespread commercialization. Developments in molecular engineering and self assembly, as well as in conducting polymers, are enabling better performance and greater scientific understanding of the phenomena underlying these advances. Improvements in electro-optic, photorefractive and two-photon absorbing materials are also being realized and are addressed here.
