Available in PDF, EPUB and Kindle. Book excerpt: Ceramic composites exhibiting increased fracture toughness are produced by the simultaneous codeposition of silicon carbide and titanium disilicide by chemical vapor deposition. A mixture of hydrogen, methyltrichlorosilane and titanium tetrachloride is introduced into a furnace containing a substrate such as graphite or silicon carbide. The thermal decomposition of the methyltrichlorosilane provides a silicon carbide matrix phase and the decomposition of the titanium tetrachloride provides a uniformly dispersed second phase of the intermetallic titanium disilicide within the matrix phase. The fracture toughness of the ceramic composite is in the range of about 6.5 to 7.0 MPa.sqroot.m which represents a significant increase over that of silicon carbide.

Available in PDF, EPUB and Kindle. Book excerpt: Discovered by Edward G. Acheson about 1890, silicon carbide is one of the oldest materials and also a new material. It occurs naturally in meteorites, but in very small amounts and is not in a useable state as an industrial material. For industrial require ments, large amounts of silicon carbide must be synthesized by solid state reactions at high temperatures. Silicon carbide has been used for grinding and as an abrasive material since its discovery. During World War II, silicon carbide was used as a heating element; however, it was difficult to obtain high density sintered silicon carbide bodies. In 1974, S. Prochazka reported that the addition of small amounts of boron compounds and carbide were effective in the sintering process to obtain high density. It was then possible to produce high density sintered bodies by pressureless sintering methods in ordinary atmosphere. Since this development, silicon carbide has received great attention as one of the high temperature structural ceramic materials. Since the 1970s, many research papers have appeared which report studies of silicon carbide and silicon nitride for structural ceramics.

Book excerpt: It has been three decades since the last significant book was published on SiC ceramics (other than those books that specifically focus on SiC semiconductors). Thirty years has been a long time in the world of SiC ceramics. In the early 1990s, SiC was still a relatively obscure ceramic even within the materials community, prominent only as an industrial abrasive (carborundum), and a refractory (Chapter 7). This has all changed dramatically in the 21st century. For example, As a semiconductor, SiC greatly surpasses silicon in performance, especially in high-power systems. Its market penetration since its launch in 2001 has been exponential. Single-crystal SiC semiconductors are covered in Chapter 3 Millions of military and paramilitary personnel have globally been protected with lightweight SiC body armour, since the late 1990s. Body armour is covered in Chapters 4 and 5 SiC–SiC is a composite material close to commercialization that makes possible high-temperature load-bearing applications hitherto only able to be hypothesized: from ultra-high-temperature jet turbine blades to advanced nuclear fuel encapsulation, the possibilities are very promising. Aerospace applications are covered in Chapter 9 Other key areas that are addressed are blast-resistant SiC vehicle/vessel armour in Chapter 8 and wear-resistant SiC ceramics in Chapter 6 Silicon Carbide Ceramics will be an essential reference resource for academic and industrial researchers and materials scientists and engineers working in ceramic materials for the semiconductor, defence, aerospace, wear resistance and refractory fields Presents an extensive review of the history, production and properties of SiC ceramics, including their characterization and applications Discusses classical and state-of-the-art sintering technologies for SiC ceramics Focuses on the future of ceramic manufacturing and advanced ceramic additive technologies
Download or read book Superalloys Supercomposites and Superceramics written by John K Tien and published by Elsevier. This book was released on 2012-12-02 with total page 789 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superalloys, Supercomposites and Superceramics reviews the state of superalloy technology and some of the more salient aspects of alternative high temperature systems such as superceramics and supercomposites. Superalloy topics range from resource availability to advanced processing such as VIM, VAR, and VADAR, along with investment casting and single crystal growth, new superplastic forming techniques and powder metallurgy, structure property relationships, strengthening mechanisms, oxidation, hydrogen embrittlement, and phase predictions. This book is comprised of 22 chapters that explore key issues of high temperature materials in a synergistic manner. The first chapter reflects on the growth of the superalloy industry and its technology over the past 40 years. The discussion then turns to some of the trends in superalloy development, focusing on what is understood to be meant by the term strategic materials and the current status of resources and reserves in the United States. Particular attention is given to the supply sources and availability of strategic materials. The results achieved from the research program undertaken by NASA Lewis Research Center named Conservation Of Strategic Aerospace Materials (COSAM) are also presented. The chapters that follow explore alternative high temperature systems such as intermetallics, fiber reinforced superalloys, and the processing and high temperature properties of ceramics and carbon-carbon composites. This book will be a valuable resource for professionals and graduate students interested in learning about superalloys, supercomposites, and superceramics.

This book was released on 2018-10-23 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructural characterization of two reaction-formed silicon carbide ceramics has been carried out by interference layering, plasma etching, and microscopy. These specimens contained free silicon and niobium disilicide as minor phases with silicon carbide as the major phase. In conventionally prepared samples, the niobium disilicide cannot be distinguished from silicon in optical micrographs. After interference layering, all phases are clearly distinguishable. Back scattered electron (BSE) imaging and energy dispersive spectrometry (EDS) confirmed the results obtained by interference layering. Plasma etching with CF4 plus 4% O2 selectively attacks silicon in these specimens. It is demonstrated that interference layering and plasma etching are very useful techniques in the phase identification and microstructural characterization of multiphase ceramic materials.

Book excerpt: The high expectations set on ceramic materials in recent years have always been balanced by the very considerable difficulties seen in reaching the required levels of reproducibility and cost. Indications of the significant progress, which can be seen in the papers presented in this volume, coupled with the recognition that considerable problems still lie between the state of the art and the full and confident exploitation of the many merits of ceramics, provide a healthy basis for the profitable selection of future research directions. The mastery of ceramic processing and the imaginative matching of the properties of these materials to diverse applications remain among the most promising sectors for technological development.
