Book Description
Over recent years the understanding of grain boundaries, interphase boundaries and free surfaces has advanced greatly, leading to a clear recognition that these discontinuities make a significant contribution to the physical and mechanical properties of materials from multiphase metals and alloys to electronic materials. Grain Boundaries -Their Microstructure and Chemistry discusses the interrelationship between microstructure and chemistry of the grain boundary, with particular emphasis on the influence of the environment (air, liquid and liquid metal) and composition (bulk and impurity). This highly practical volume presents a brief background to interphase and grain boundaries, before considering in detail grain boundary composition and composition changes, and how grain boundary composition affects material properties. Very recent advances in techniques such as electron energy loss spectroscopy, high-resolution transmission electron microscopy and atom probe, and the facinating new insights into grain boundary, microstructure that they have revealed, are also discussed. Grain Boundaries - Their Microstructure and Chemistry is an indispensable text for design and safety engineers in many industries, including power and aerospace, as well as for materials scientists and engineers in academia and research institutes.

Book Description
The challenges of space exploration are a great stimulus to our technologies today. Development of successful aerospace programs has required the best efforts of the scientist and engineer in almost every discipline. Not so long ago, it truly could be said that designers are trying to develop tomorrow's vehicles with yesterday's materials. Unfortunately, we find that the situation remains nearly the same today. The purpose of this conference was to identify materials, proces ses, and methods that show the greatest potential in future space technology and to define the gap between mission requirements and materials application. Of the many properties of materials, the one in which the largest gap between fundamental understanding and practical application appears to exist is the mechanical property, particularly of crystalline materials. The emphasis on crystalline materials is a natural one. It is these materials which are used primarily when demands are placed on mechanical strength, especially at elevated temperatures. The advent of space exploration requires the utilization of materials in environments and under conditions that are a challenge to the resourcefulness and ingenuity of the scientist and engineer. The scientist can, as a result of the past thirty years' work, relate mechanical properties to the formation, motion, and interaction of individual crystalline defects, such as vacancies, interstitials, and dislocations. Furthermore, he can, by controlled preparation of his materials, confine his studies to those cases in which the concentration of crystal defects is conveniently low.

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.
