Sintered Metallic And Ceramic Materials

Sintering is one of the most important industrial techniques for optimizing the capabilities of different materials and this book deals exclusively with the state-of-the-art on the processing of sintered materials, both metallic and ceramic. Emphasis is placed on on the relationship between the composition of the material, the powder processing techniques used and the properties of the materials and the applications of end products. Materials covered include: ferrous (low and high alloy steels) and nonferrous (light and heavy) alloys, rare earth intermetallics, ceramics (oxide and nonoxide) and cermets. The various applications of sintered materials in the automotive, aerospace and defence, machine tool and power industries and in magnetic, electrical, and electronic applications are discussed in the final chapter. This book will be used by engineers working with sintering techniques and sintered materials and by engineering students studying powder metallurgy. The author is internationally renowned for his work on sintering and sintered materials.

The book covers new sintering techniques on ceramic materials, metals and composites as well as reprocessed PTFE. The book covers theoretical as well as experimental aspects on Spark Plasma Sintered (SPS) Porous copper, development of cutting blades with high hardness and resistance to cracking and wear, increased microhardness of austenitic steel ? TiB2 composites obtained with high pressure - high temperature sintering, Al2O3 porous body with cotton as the template and excellent thermal insulation with direct application for refractories as well as Metal matrix composites added nanostructured tantalum carbide and an overview of different sintering techniques used in powder metallurgy. Finally recycling of PTFE scrap materials using ram extrusion and compression molding is described.

The chapters covered in this book include emerging new techniques on sintering. Major experts in this field contributed to this book and presented their research. Topics covered in this publication include Spark plasma sintering, Magnetic Pulsed compaction, Low Temperature Co-fired Ceramic technology for the preparation of 3-dimesinal circuits, Microwave sintering of thermistor ceramics, Synthesis of Bio-compatible ceramics, Sintering of Rare Earth Doped Bismuth Titanate Ceramics prepared by Soft Combustion, nanostructured ceramics, alternative solid-state reaction routes yielding densified bulk ceramics and nanopowders, Sintering of intermetallic superconductors such as MgB2, impurity doping in luminescence phosphors synthesized using soft techniques, etc. Other advanced sintering techniques such as radiation thermal sintering for the manufacture of thin film solid oxide fuel cells are also described.

Ceramics are, in a general definition, materials that consist of man-made, inorganic, non-metallic solid material - either existing in a crystalline state or non-crystalline state (i.e., glasses). Materials characterization techniques are used to ensure the structural and surface integrity of ceramics for their use in a wide variety of applications, from thermal resistance to advanced electronic and optical technologies like fiber optics to structural uses. This book presents those techniques along with views on future trends in ceramics processing and advanced characterization technologies particularly appropriate to ceramics materials. Readers will find more on: Ceramic Materials preparation routes, including powder preparation by solution techniques and gas-phase techniques Formation techniques for ceramic films and coatings, thick films and bulk ceramics A review of ceramic microstructure, reactions, phase behavior, mechanical properties and electronic and magnetic ceramics

As the field's premiere source, this reference is extensively revised and expanded to collect hard-to-find applications, equations, derivations, and examples illustrating the latest developments in ceramic processing technology. This book is concerned primarily with the processing of polycrystalline ceramics and focuses on the widespread fabrication of ceramics by the firing of consolidated powders forms. A brief treatment of sol-gel processing is also included. Ceramic Processing and Sintering, Second Edition provides clear and intensive discussions on colloidal and sol-gel processing, sintering of ceramics, and kinetic processes in materials. From powder synthesis and consolidation to sintering and densification behavior, this latest edition emphasizes the impact of each processing procedure on ceramic properties. The second edition also contains new and extended discussions on colloid stability, polymer growth and gelation, additives in ceramic forming, diffusion and defect strucutre, normal and abnormal grain growth, microwave sintering, Rayleigh instability effects, and Ostwald ripening. Illustrating the interconnectedness between the various steps in the overall fabrication route, Ceramic Processing and Sintering, Second Edition approaches the fundamental issues of each process and show how they are applied to the practical fabrication of ceramics.

Silicon carbides have major industrial uses as high temperature structural ceramic materials. These two volumes are translated from the Japanese and provide a comprehensive account of the seminal work going on in Japan.
