There has been a renaissance in glass science brought about by the development of concepts such as fragility index and the energy landscape with megabasins. Research on bulk metallic glasses has been explosive since their advent when MRS offered its first book on the topic. In 2000, a second book broadened the scope to include supercooled liquid, bulk glassy and nanocrystalline states. This book enhances the scope to include glass transition in diverse materials such as water, silicate and polymeric melts. Bringing these threads together in an interdisciplinary manner was fruitful and offers proof that while there is much common ground, gaps between various approaches to the glassy state remain to be bridged. Subjects include: the supercooled liquid; glass formability; structural relaxation and dynamics; structure determination and modeling; processing and applications of bulk metallic glasses; mechanical properties; mechanical properties - composites; crystallization; electronic and magnetic structure and properties; and nanoparticles and nonmetallic glasses.

In spite of the large amount of research activity in this subfield of materials science and engineering, there is no single book available that provides background information, methods of synthesis, characterization procedures, properties, and potential and existing applications.of bulk metallic glasses. Written in an easy-to-understand style by pioneering researchers in this field, Bulk Metallic Glasses is one of the first books to coherently discuss the synthesis, processing, properties, and applications of these unique materials. The book explores the differences between nanocrystalline, glassy, and amorphous solids as well as the thermodynamics and kinetics and various processing methods of glass formation. It critically compares the different criteria for glass formation, describes the advantages and limitations of experimental methods for synthesizing bulk metallic glasses in assorted sizes and shapes, and examines the kinetics of crystallization/devitrification and the mechanisms of transformations. It also covers the density, diffusivity, thermal expansion, electrical resistivity, specific heat, viscosity, corrosion resistance, mechanical behavior, and magnetic properties of bulk metallic glasses. After presenting a wide array of applications, the book concludes with a discussion on the future of these materials. The adoption of bulk metallic glasses into existing systems is besieged by many obstacles but due to their interesting combination of properties, future applications may be unlimited. A one-stop resource on all aspects of bulk metallic glasses, this book demonstrates the immense potential of these novel materials. It clearly elucidates the background, detailed methods of synthesis and characterization, structure, and properties of bulk metallic glasses.

Metallic glasses are very promising engineering and functional materials due to their unique mechanical, chemical, and physical properties, attracting increasing attention from both scientific and industrial communities. However, their practical applications are greatly hindered due to three main problems: dimensional limit, poor tension plasticity, and difficulty in machining and shaping. Therefore, further investigation of these issues is urgently required. This book provides readers with recent achievements and developments in the properties and processing of metallic glasses, including mainly thermoplastic forming of metallic glasses (Chapter 2), atomic-level simulation of mechanical deformation of metallic glasses (Chapter 3), metallic glass matrix composites (Chapter 4), and tribo-electrochemical applications of metallic glasses (Chapters 5 and 6).

Three properties of bulk metallic glasses were investigated: (1) atomic motions; (2) characteristics of bonding and electronic states; (3) fracture. Atomic motion in glassy PdNiCuP was investigated by NMR over a wide temperature range from below the glass transition temperature Tg to above the liquidus temperature Tliq. This study reveals the temperature in the supercooled liquid region, below which motions of different elements begin to diverge. It sheds light on the nature of the crossover temperature Tc proposed by mode coupling theory. Also, hopping was shown to persist below Tg. The electronic states of various metallic glasses were studied by NMR including CuZrAl, Ce-based, and Y-based alloys. Results established some correlation between the glass forming ability and the characteristics of electronic states. This sheds light on the structure and formation of metallic glasses. Finally, we studied the fracture surfaces of various bulk metallic glasses including the brittle Mg-based bulk metallic glass. We established a clear correlation between the fracture toughness and plastic process zone size for various glasses. The results indicate that the fracture in brittle metallic glassy materials might also proceed through the local softening mechanism but at different length scales.

In the fall of 1998, Prof. Sergey Firstov invited me to the Frantcevych Institute for Problems of Materials Science (IPMS) in Kyiv, Ukraine to discuss possible collaborations in the area of advanced metals research. During this visit, a strong mutual interest was evident in a broad range of structural metals technologies, and a quick friendship was established. Countless subsequent emails and a reciprocal visit to the U. S Air Force Research Laboratory by Prof. Firstov and a team of scientists from IPMS ensued to discuss and detail a broad collaboration in the area of structural metals. Two years after the initial visit, a major investment by the U. S. Air Force Office of Scientific Research (AFOSR) was established to pursue the technologies defined by these interactions. The annual reviews of the AFOSR Ukrainian Metals Initiative were held in late May, a most beautiful time in Kyiv when the lilacs are in bright display and the air is scented with the smell of falling blossoms from the chestnut trees that line the major streets and many parks. The sunny days and mild evenings provide a welcome break from winter, and on weekend evenings festive crowds spill onto the Khreshchatyk, Kyiv’s downtown boulevard, to listen to street musicians, watch jugglers and comedians, or simply to celebrate with friends. The annual reviews featured long days of intensive discussion of technical progress, followed in the evenings by the warm hospitality of the Ukrainian hosts.

This year's nitride symposium showed the scope of nitride-related advances spanning basic materials physics over process technology to high-performance devices. Progress was reported in bulk growth of GaN and AlN, growth on various substrates and substrate orientations, optical properties of InN, defect and doping analysis of p-doped GaN, and polarization properties. These led to new performance records in visible light emitter technology, i.e., higher efficiency/higher brightness, UV emitters with shorter wavelength, and UV and photo detectors. Advances in the development of nitride-based electronic devices with new heterostructure FET designs for RF power applications, including those on Si substrates and wafer fusion, are also reported. This book captures the exciting developments in this rapidly progressing field. Topics include: epitaxy - devices and defect reduction; defects and characterization; epitaxy - nonpolar orientations and alloys; optical properties; UV emitters and detectors; visible light emitters; electronic devices; characterization of defects and transport; and contacts, processing and p-type nitrides.

This book contains the proceedings of two symposia held at the 2002 MRS Fall Meeting in Boston. Papers from Symposium T, Crystalline Oxides on Semiconductors, bring together experts from different technology areas - high-k gate dielectrics, novel memories, and ferroelectrics, for example - to examine commonality among the fields. These papers offer an overview of the field, highlight interesting experimental results and device ideas, and feature innovative theoretical approaches to understanding these systems. Symposium V, Interfacial Issues for Oxide-Based Electronics, covers a wide range of topics involving the interfaces between electro-optical oxide layers and other materials. Overall, it is clear that a new generation of materials and heterostructures has been enabled by the increasing control of interfacial phenomena. Topics include: epitaxial oxide-silicon heterostructures; ferroelectric thin films on silicon; theory and modeling; crystalline oxides for gate dielectrics; transparent conducting oxides; transparent conducting oxides and oxide growth and properties; field effect devices and gate dielectrics; ferroelectrics, capacitors and sensors; organic devices and interfacial growth issues.
