Key Engineering Materials
The continuing growth of PM parts in a great number of applications has resulted in intense world-wide research and development efforts in the field. Recent advances in powder technology are presented in the areas of synthesis and processing of various ceramics, including electroceramics, biometarials and nanocomposites; powder production and compaction, sintering, processing and characterization of important alloys and metal matrix composites. Properties of particular interest are corrosion, mechanical and magnetic properties.
The light metals (aluminum, magnesium and titanium) are important for many applications, but are most critical for transportation where weight savings results in a plethora of benefits including reduced fuel consumption, higher speed and longer range, improved performance/handleability, etc. This applies whether we are dealing with automobiles, airplanes, space vehicles, bicycles or even submarines – witness the titanium alpha class submarine in “Hunt for Red October”.
Fracture, Fatigue and Strength are among the most important properties of engineering materials. The present volume covers all aspects of Fracture Mechanics, Computational Mechanics, Dynamic Fracture, Damage Mechanics, Fracture Physics, Fatigue and Creep of advanced materials, special emphasis being placed on Polymer and Polymer Composites, Metal Matrix and Ceramic Matrix Composites, Advanced Ferrous and Nonferrous Alloys and Nonmetallic Materials. Also covered are various Structural Aspects, Welding and Joining Properties, Stress Corrosion, Dynamic Loading Effects and other aspects limiting the Application of High-Tech Materials.
Electroceramics are among the most interesting and useful materials for electronic devices, and various other high-technology applications. The present volume discusses dielectric, piezoelectric, semiconductive, ionically conducting and superconductive materials. Special emphasis is placed on the characterization of these materials, including computer simulations, and on the fabrication procedures for bulk and thin film ceramics on the submicronmeter scale. Important results are reported on grain boundary phenomena and the effects of various crystal and surface structures on the technologically important properties of electroceramics.
From the early industrial revolution, metal working has been the major driving force for the development of many manufacturing technologies. “Advances in Engineering Plasticity” reports on recent developments in the field of metal forming and plasticity research from both the fundamental science and industrial application perspective.
This work represents a new approach to ceramics research. The mechanical properties of ceramics and ceramic-based composites are well understood and have been studied extensively in the past. This more profound understanding of physical properties, such as particularly low or high thermal conductivities, radiation penetration depth, electrical and magnetic responses etc., can now lead to the development of new materials having improved properties.
Recent research on the creep and fracture of engineering materials is presented, with particular emphasis being placed on: mechanisms of high-temperature deformation and fracture, materials for high-temperature service, the behavior of single and polycrystals, components and structures, grain boundaries and interfaces, and superplasticity.
This book presents the latest research results on conductive ceramics; dielectrics; piezo-electric ceramics; ZnO semiconducting ceramics; insulators; batteries and cells; and memory devices.
Understanding the manner in which damage evolves in engineering materials, systems or structures is currently the focus of extensive research. The object of the present book is to report recent advances in the areas of damage detection, assessment and quantification.
The application of ceramic materials is currently expanding into a wide range of areas, e.g. gas turbine assembly, engine components, electronic devices, bio-materials etc. But because ceramics pose problems with respect to their brittleness and low reliability, due to their intrinsic nature and/or processing defects, research related to the deformation and fracture of ceramics is still a subject of high priority.
