Key Engineering Materials
Concrete is, both practically and metaphorically, one of the major civil-engineering materials supporting modern society. But both concrete technology, and its structures, face daunting challenges arising from environmental erosion and other natural, and man-made, hazards.
This collection is the result of bringing together scientists from various countries in order to combine their knowledge concerning the latest analytical, experimental and numerical developments in the fields of Strength of Materials, Fracture Mechanics and Fatigue.

The Bioceramics 21 Proceedings includes a section which is devoted to theoretical modelling; an important and new issue which involves several fields of knowledge. This trend is reflected by the high number of papers involving both biological and materials sciences. Following the evolution of regenerative medicine, a third generation of bioceramics is represented in these Proceedings by the variety of papers on tissue engineering, nanotechnology and smart materials.
Advanced high-temperature materials are key players in the emerging new technologies which are pushing forward the structural-aerospace, propulsion-system, defense, nuclear, thermal and chemical industries. Accelerating efforts have been directed towards increasing the operating-temperature limits of existing material systems and developing new material compositions such as advanced ceramics, UHTCs, intermetallics and CMCs. Understanding and controlling the behavior of the microstructures and properties of such materials have become key elements in these research activities. Since processing may itself engender various unique microstructural configurations and properties, the routes taken when obtaining optimum structures are also of primordial importance.
The present volume comprises a collection of peer-reviewed papers covering innovations and practical experience regarding manufacturing automation education; current and developing manufacturing automation; advanced manufacturing technology including flexible manufacturing, virtual manufacturing, Green manufacturing and re-manufacturing, and web-based manufacturing; computer-integrated manufacturing systems; CAD/CAE/CAPP/CAM; product life-cycle management (PLM); computerized numerical control systems and flexible manufacturing systems; industrial robotics; process monitoring and quality control of manufacturing systems; group technology (GT); PDM, ERP, logistics and supply chains.
This book presents contributions covering the more recent applications of Sol-Gel science. Ceramics and films produced from gels were among the first applications developed by early sol-gel researchers. The possibility of tailoring the structure, and controlling particle growth, has permitted ever more advanced materials to be obtained. Several other potential applications were foreseen fifteen to twenty year ago, but their realization became possible only after extensive research on precursors had enabled progress towards the preparation of new pre-forms.
Abrasive technology concerns manufacturing processes that involve the use of abrasives in various forms. It has a long history; originating right from the first discovery of minerals. With increasingly stringent requirements for the production of high-precision and high surface-quality components, in applications such as silicon wafers for the semiconductor industry and optical lenses for the precision instrument industry, abrasive technology is becoming an increasingly important factor in precision manufacturing. An understanding of the mechanisms of abrasive technology ensures the soundness and integrity of current component manufacture, as well as leading to the development of new and effective techniques.
Japan is currently the most active country among those carrying out research into the rapidly expanding sphere of Electroceramics; a field that holds tremendous promise for expanding or opening-up a wide range of high-tech applications.
This volume is made up of contributions from researchers in 22 countries. It aims to promote exchange of the latest experimental and theoretical results on structural integrity, durability and failure analysis; with the emphasis on fracture and damage mechanics.
All components and mechanical parts have surfaces which are either exposed to a particular environment or are in contact with other components. Consequent corrosion and/or wear of the surface may then lead to destructive failure. A so-called “bad” surface is a favoured spot for crack initiation, resulting in a decrease in the fatigue, tensile properties and even toughness of materials. Although the development of new materials can improve the surface properties, this can also lead to a change in the properties of the substrate. For example, increasing the carbon content significantly improves the wear resistance of steels, but toughness has to be sacrificed. Increased cost is another major concern. Moreover, for some components, such as gears, a ductile substrate and a hard surface are required. In this case, surface treatment remains the only choice. Surface modification, also termed surface treatment, has thus been recognised as being a major emergent manufacturing technology for improving the surface properties, with minimal alteration of the substrate.
