Book Description
This edition has been greatly enlarged and updated to provide both scientists and engineers with a clear and comprehensive understanding of composite materials. In describing both theoretical and practical aspects of their production, properties and usage, the book crosses the borders of many disciplines. Topics covered include: fibres, matrices, laminates and interfaces; elastic deformation, stress and strain, strength, fatigue crack propagation and creep resistance; toughness and thermal properties; fatigue and deterioration under environmental conditions; fabrication and applications. Coverage has been increased to include polymeric, metallic and ceramic matrices and reinforcement in the form of long fibres, short fibres and particles. Designed primarily as a teaching text for final-year undergraduates in materials science and engineering, this book will also interest undergraduates and postgraduates in chemistry, physics, and mechanical engineering. In addition, it will be an excellent source book for academic and technological researchers on materials.

Book Description
In the past twenty years, new experimental approaches, improved models and progress in simulation techniques brought new insights into long-standing issues concerning dislocation-based plasticity in crystalline materials. During this period, three-dimensional dislocation dynamics simulations appeared and reached maturity. Their objectives are to unravel the relation between individual and collective dislocation processes at the mesoscale, to establish connections with atom-scale studies of dislocation core properties and to bridge, in combination with modelling, the gap between defect properties and phenomenological continuum models for plastic flow. Dislocation dynamics simulations are becoming accessible to a wide range of users. This book presents to students and researchers in materials science and mechanical engineering a comprehensive coverage of the physical body of knowledge on which they are based. It includes classical studies, which are too often ignored, recent experimental and theoretical advances, as well as a discussion of selected applications on various topics.

Book Description
Dislocations deals with the main properties of dislocations, including motion, climb, and vacancies. Topics covered include the elastic theory of dislocations, imperfect dislocations, and crystal growth, along with dislocation networks, annealing, and grain boundaries. The interaction of dislocations with other defects is also discussed. This book is comprised of 17 chapters and begins with an overview of the general properties of dislocations, with emphasis on perfect and real crystals and the general case for translation dislocations. The reader is then introduced to the motion of dislocations, including glide; vacancies and interstitial atoms; dislocation climb; imperfect dislocations and surfaces of misfit; and crystal growth, including growth from a liquid phase. The next section is devoted to the more or less complex networks of dislocations that can be formed in crystals, and to the plastic properties corresponding to these arrays. The remaining chapters explore the interactions of dislocations with other crystalline defects, primarily impurity atoms. This monograph is intended for physicists, metallurgists, materials scientists, research and engineering students, and research engineers.

Book Description
The subject of mechanical behavior has been in the front line of basic studies in engineering curricula for many years. This textbook was written for engineering students with the aim of presenting, in a relatively simple manner, the basic concepts of mechanical behavior in solid materials. A second aim of the book is to guide students in their laboratory experiments by helping them to understand their observations in parallel with the lectures of their various courses; therefore the first chapter of the book is devoted to mechanical testing. Another aim of the book is to provide practicing engineers with basic help to bridge the gap of time that has passed from their graduation up to their actual involvement in engineering work. The book also serves as the basis for more advanced studies and seminars when pursuing courses on a graduate level. The content of this textbook and the topics discussed correspond to courses that are usually taught in universities and colleges all over the world, but with a different and more modern approach. It is however unique by the inclusion of an extensive chapter on mechanical behavior in the micron and submicron/nanometer range. Mechanical deformation phenomena are explained and often related to the presence of dislocations in structures. Many practical illustrations are provided representing various observations encountered in actual structures of particularly technical significance. A comprehensive list of references at the end of each chapter is included to provide a broad basis for further studying the subject.

Book Description
The proposed existence of the edge and screw dislocation in the 1930s, and the subsequent work showing that dislocation theory could explain the plastic deformation of crystals, represent an important step in developing our understanding of materials into a science. The continued work involved with characterization of dislocations and linking them to a variety of physical properties in both single and poly crystals have made enormous progress over the past 50 years. It is rare to find a technical application involving a material with any crystal structure that is not impacted by dislocations; mechanical properties, massive phase transformations, interphases, crystal growth, electronic properties, the list goes on. In many systems the properties is controlled by the formation of partial dislocations separated by a stacking fault; for example plastic deformation via deformation twinning. And finally, giant strides have been made in characterization and modeling of systems containing dislocations. The Special Issue on “Crystal Dislocations” is intended to provide a unique international forum aimed at covering a broad range of results involving dislocations and their importance on crystal properties and crystal growth. Scientists working in a wide range of disciplines are invited to contribute to this cause.Dr. K. Peter D. Lagerlof, Associate Professor of CeramicsGuest Editor

Book Description
This is a very special book for two reasons. First, it is a tribute to Professor Sir Peter Hirsch from his students, colleagues and friends. Second, it is a collection of specially written review articles by world-class scientists that take the readers from the origins of modem materials science through to the cutting edge of the subject in the twenty- first century. The book will be a valuable resource for all researchers in materials science, particularly those specialising in electron microscopy and diffraction, and in the mechanical properties of materials. The front and back covers of this book are coloured images of historic electron micrographs depicting the first observation in the world of moving dislocations. The pictures were taken by Mike Whelan, then a research student of Peter Hirsch. The image on the front cover is before some dislocations have moved, and the back cover image is after the movement. See if you can spot the difference! This book had its genesis in a symposium organised by Mike Goringe, John Hutchison and myself to mark the retirement of Peter Hirsch from the Isaac Wolfson Chair of Metallurgy at Oxford. This symposium brought together a large number of Peter's former students and colleagues. Some of the most distinguished of these have now written the chapters in this book. The opening chapter, by Professor Ugo Valdre, provides a fascinating biographical sketch of Peter Hirsch from his early career in Cambridge to his retirement in Oxford. It contains many illuminating insights into the personality of Peter, both as a scientist and as a man. The next two chapters focus on the development of electron microscopy and diffraction. Professor Mike Whelan gives an eye-witness account of the seminal early work of Peter and his colleagues at Cambridge on the first observation of dislocations and their movements, using trans-mission electron microscopy. Professor Archie Howie extends this account to the present day, describing nanometer-scale resolution in scanning electron microscopes and atomic scale resolution in the scanning tunnelling microscope.
