The theory of how metals conduct electronically had for a long time been confined to metals that are crystalline with the constituent atoms in regular arrays. The discovery of how to make solid amorphous alloys led to an explosion of measurements of the electronic properties of these new materials, and the emergence of a range of interesting low temperature phenomena. This 1995 book describes in physical terms the theory of the electrical conductivity, Hall coefficient, magnetoresistance and thermopower of disordered metals and alloys. The author begins by showing how conventional Boltzmann theory can be extended and modified when the mean free path of the conduction electrons becomes comparable with their wavelength and interionic separation. The consequence of this is explored and the theory tested by application to experimental data on metallic glasses. Designed as a self-contained review, the book will appeal to non-specialist physicists, metallurgists and chemists with an interest in disordered metals.

This book provides an in-depth treatment of the instrumentation, physical bases and applications of X-ray photoelectron spectroscopy (XPS) and static secondary ion mass spectroscopy (SSIMS) with a specific focus on the subject of polymeric materials. XPS and SSIMS are widely accepted as the two most powerful techniques for polymer surface chemical analysis, particularly in the context of industrial research and problem solving. In this book, the techniques of XPS and SSIMS are described and in each case the author explains what type of information may be obtained. The book also includes details of case studies emphasising the complementary and joint application of XPS and SSIMS in the investigation of polymer surface structure and its relationship to the properties of the material. This book will be of value to academic and industrial researchers interested in polymer surfaces and surface analysis.

This book describes the properties and device applications of hydrogenated amorphous silicon. It covers the growth, the atomic and electronic structure, the properties of dopants and defects, the optical and electronic properties which result from the disordered structure and finally the applications of this technologically very important material. There is also an important chapter on contacts, interfaces and multilayers. The main emphasis of the book is on the new physical phenomena which result from the disorder of the atomic structure. The book will be of major importance to those who are researching or studying the properties and applications of a-Si:H. It will have a wider interest for anyone working in semiconductor physics and electronic engineering in general.

This book addresses the issue of designing the microstructure of fiber composite materials in order to obtain optimum performance. Besides the systematic treatment of conventional continuous and discontinuous fiber composites, the book also presents the state-of-the-art of the development of textile structural composites as well as the nonlinear elastic finite deformation theory of flexible composites. The author's experience during twenty years of research and teaching on composite materials is reflected in the broad spectrum of topics covered, including laminated composites, statistical strength theories of continuous fiber composites, short fiber composites, hybrid composites, two- and three-dimensional textile structural composites and flexible composites. This book provides the first comprehensive analysis and modeling of the thermo-mechanical behavior of fiber composites with these distinct microstructures. Overall, the inter-relationships among the processing, microstructures and properties of these materials are emphasized throughout the book. The book is intended as a text for graduate or advanced undergraduate students, but will also be an excellent reference for all materials scientists and engineers who are researching or working with these materials.

The aim of this 1981 book, designed for senior undergraduates, postgradutes and professionals, is to draw together in one unified presentation a number of the phenomena associated with polymer surfaces. The author begins by describing the theory of surface tension in terms of intermolecular forces and then goes on to consider the practical problem of the factors involved when a liquid wets a polymeric surface and forms a bond to it. An account of polymeric adhesives and their different spheres of application follows, and an examination of the mechanism of failure of adhesive joints leads to a discussion of joint design for optimum strength and environmental resistance. A chapter on friction is closely related to that on adhesion, and the final chapter is devoted to specific frictional mechanisms associated with high hysteresis polymers as well as an introductory discussion of wear.

The nature of the solid-liquid interface, the mechanism associated with its movement, and its preferential morphologies, impose important boundary conditions on the technology of crystal growth from the melt. This 1973 book sets out to describe these basic physical changes which underlie all of the important range of melt growth techniques irrespective of the special problems of individual materials and particular experimental techniques. It will be of particular value to senior undergraduates and graduate students of the science of materials. Dr Woodruff begins by considering Gibbs's 1878 work on the basic thermodynamics of an interface, and moves on to examine experimental aspects of the solid-liquid interfacial free energy. The theory of the morphological stability of the interface is also studied, along with the kinetics of crystal growth, and there is a useful chapter on eutectic growth. Throughout, the macroscopic properties of the materials under discussion are linked to relevant theory.

Now in paperback, this comprehensive book is the first text devoted to the problem of understanding the electrical properties of metals and alloys. Dr Rossiter, well-known for his work on the electrical resistivity of alloys, has written a book which blends results and theory, but does not rely on a strong grounding in quantum mechanics. After an introduction to the basic ideas, the concepts of atomic and magnetic correlations and their microstructural consequences are explained. Later chapters then deal with the effects of such correlations on electrical resistivity. Examples and applications of the concepts derived are given in discrete sections, allowing the uninterrupted development of theory for each specific problem, and enhancing the value of the book for a wide range of readers from theoretical and experimental solid state physicists to metallurgists and materials scientists. Anyone with an interest in the electrical conduction process or in the application of resistivity measurements to the study of alloy configuration will find this essential reading.

This is an advanced text for higher degree materials science students and researchers concerned with the strength of highly brittle covalent-ionic solids, principally ceramics. It is a reconstructed and greatly expanded edition of a book first published in 1975. The book presents a unified continuum, microstructural and atomistic treatment of modern day fracture mechanics from a materials perspective. Particular attention is directed to the basic elements of bonding and microstructure that govern the intrinsic toughness of ceramics. These elements hold the key to the future of ceramics as high-technology materials - to make brittle solids strong, we must first understand what makes them weak. The underlying theme of the book is the fundamental Griffith energy-balance concept of crack propagation. The early chapters develop fracture mechanics from the traditional continuum perspective, with attention to linear and nonlinear crack-tip fields, equilibrium and non-equilibrium crack states. It then describes the atomic structure of sharp cracks, the topical subject of crack-microstructure interactions in ceramics, with special focus on the concepts of crack-tip shielding and crack-resistance curves, and finally deals with indentation fracture, flaws, and structural reliability.

Metal matrix composites constitute a new class of materials, now starting to make a major industrial impact in fields as diverse as aerospace, automotives and electronics. This book gives a comprehensive, integrated coverage of these materials, including the background to analytical-, experimental-, production and application-oriented aspects. Clear pictorial descriptions are given of the basic principles governing various properties and characteristics; these encompass mechanical, thermal, electrical, environmental and wear behaviour. Coverage also extends to material processing and component fabrication aspects and to a survey of commercial usage. This book is aimed primarily at scientists, engineers, production managers and all those involved in research on new materials in general, and metal matrix composites in particular, but may also be suitable for use as a text in beginning graduate and advanced undergraduate courses.

This book is an introduction to polymers and focuses on the synthesis, structure and properties of the individual molecules that constitute polymeric materials. It approaches polymeric materials from a molecular basis on the belief that there is a common core of knowledge and principles concerning polymer molecules that can be set out in an introductory work. Subjects treated include an introductory overview of synthesis, an introduction of the concept and definition of molecular weight and its distribution, experimental methods for measuring molecular weight, a more detailed view of polymerization including kinetics and mechanism, and the three-dimensional architecture of polymers as determined by conformation and stereochemistry. The statistical description of the conformational disorder of the molecules is covered and then built upon in treating rubber elasticity and polymer solutions.

This book is a comprehensive introduction to the mechanical properties of ceramics, and is designed primarily as a textbook for undergraduate and graduate students in materials science and engineering. Over the past 25 years ceramics have become key materials in the development of many new technologies as scientists have been able to design these materials with new structures and properties. An understanding of the factors that influence their mechanical behavior and reliability is essential. This book will introduce the reader to current concepts in the field. It contains problems and exercises to help readers develop their skills. Although designed principally as a textbook for advanced undergraduates and graduate students, this book will also be of value as a supplementary text for more general courses and to industrial scientists and engineers involved in the development of ceramic-based products, materials selection and mechanical design.

The field of matter transport is central to understanding the processing of materials and their subsequent mechanical properties. While thermodynamics determines the final state of a material system, it is the kinetics of mass transport that governs how it gets there. This book, first published in 2000, gives a solid grounding in the principles of matter transport and their application to a range of engineering problems. The author develops a unified treatment of mass transport applicable to both solids and liquids. Traditionally matter transport in fluids is considered as an extension of heat transfer and can appear to have little relationship to diffusion in solids. This unified approach clearly makes the connection between these important fields. This book is aimed at advanced undergraduate and beginning graduate students of materials science and engineering and related disciplines. It contains numerous worked examples and unsolved problems. The material can be covered in a one semester course.
