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.

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.

Thin film mechanical behavior and stress presents a technological challenge for materials scientists, physicists and engineers. This book provides a comprehensive coverage of the major issues and topics dealing with stress, defect formation, surface evolution and allied effects in thin film materials. Physical phenomena are examined from the continuum down to the sub-microscopic length scales, with the connections between the structure of the material and its behavior described. Theoretical concepts are underpinned by discussions on experimental methodology and observations. Fundamental scientific concepts are embedded through sample calculations, a broad range of case studies with practical applications, thorough referencing, and end of chapter problems. With solutions to problems available on-line, this book will be essential for graduate courses on thin films and the classic reference for researchers in the field.

Written by a leading researcher in the field, this revised and updated second edition of a highly successful book provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, non-metals and composites. The author discusses the principles of cyclic deformation, crack initiation and crack growth by fatigue, covering both microscopic and continuum aspects. The book begins with discussions of cyclic deformation and fatigue crack initiation in monocrystalline and polycrystalline ductile alloys as well as in brittle and semi-/non-crystalline solids. Total life and damage-tolerant approaches are then introduced in metals, non-metals and composites followed by more advanced topics. The book includes an extensive bibliography and a problem set for each chapter, together with worked-out example problems and case studies. This will be an important reference for anyone studying fracture and fatigue in materials science and engineering, mechanical, civil, nuclear and aerospace engineering, and biomechanics.

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.

Mobile, wearable, and self-driving telephones are just a few examples of modern distributed networks that generate enormous amount of information every day. Due to the growing computing capacity of these devices as well as concerns over the transfer of private information, it has become important to process the part of the data locally by moving the learning methods and computing to the border of devices. Federated learning has developed as a model of education in these situations. Federated learning (FL) is an expert form of decentralized machine learning (ML). It is essential in areas like privacy, large-scale machine education and distribution. It is also based on the current stage of ICT and new hardware technology and is the next generation of artificial intelligence (AI). In FL, central ML model is built with all the data available in a centralised environment in the traditional machine learning. It works without problems when the predictions can be served by a central server. Users require fast responses in mobile computing, but the model processing happens at the sight of the server, thus taking too long. The model can be placed in the end-user device, but continuous learning is a challenge to overcome, as models are programmed in a complete dataset and the end-user device lacks access to the entire data package. Another challenge with traditional machine learning is that user data is aggregated at a central location where it violates local privacy policies laws and make the data more vulnerable to data violation. This book provides a comprehensive approach in federated learning for various aspects.
