Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide (SiC) whiskers have great potential, some already realized, in reinforcing ceramic matrix composites to give significant improvements in toughness and strength. Los Alamos has been developing the vapor-liquid-solid (VLS) process to grow single crystal BETA-SiC fibers having relatively few defects and diameters of from 3 to 5 .mu.m and lengths up to 100 mm. These whiskers have superb mechanical properties-strengths up to 16 GPa (2.3 Msi) and elastic modulus of 580 GPa (84 Msi) - and should have excellent stability at high temperatures. Two basic synthesis routes were investigated: 1) in situ SiO generation and 2) external gaseous Si source. Process 1) had a much more extensive prior developmental history and has been developed at Los Alamos to the point where significant and reproducible yields of prime whiskers can be obtained and scaleup could be considered. What we have learned about this process and its product will be the subject of this paper. 14 refs., 17 figs., 31 tabs.

This book was released on 1991 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Type C SiC whiskers showed a more obvious toughening effect for Si$\sb3$N$\sb4$ ceramics than the commercial Tokamax SiC whiskers. This might be due to the effect of interfacial bonding and/or the effect of the morphology and size of the whiskers.

Download or read book Development of the VLS Process for SiC Whisker Growth written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Our whisker work involves preparation of whisker samples, whisker characterization, and process scaleup. Sample whiskers are used for composite preparation and for whisker characterization work, while modelling of the production process is itself proving useful. The approach to scaleup recognizes the importance of a full understanding of the process variables. Hence our work in this area is proceeding with studies of the chemistry of the process gases and investigation of the growth mechanism.

Download or read book Materials Science of Carbides Nitrides and Borides written by Yury G. Gogotsi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of current research on a wide range of carbide, nitride and boride materials, covering the general issues relevant to the development and characterisation of a variety of advanced materials. Topics include structure and electronic properties, modeling, processing, high-temperature chemistry, oxidation and corrosion, mechanical behaviour, manufacturing and applications. The volume complements more specialised books on specific materials as well as more general texts on ceramics or hard materials, presenting a survey of materials research as a key to technological development. After decades of research, the materials are being used in electronics, wear resistant, refractory and other applications, but numerous new applications are possible. Roughly equal numbers of papers cover theoretical and experimental research in the general field of materials science of refractory materials. Audience: Researchers and graduate students in materials science and engineering.

This book was released on 2012-12-06 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbide, Nitride and Boride Materials Synthesis and Processing is a major reference text addressing methods for the synthesis of non-oxides. Each chapter has been written by an expert practising in the subject area, affiliated with industry, academia or government research, thus providing a broad perspective of information for the reader. The subject matter ranges from materials properties and applications to methods of synthesis including pre- and post-synthesis processing. Although most of the text is concerned with the synthesis of powders, chapters are included for other materials such as whiskers, platelets, fibres and coatings. Carbide, Nitride and Boride Materials Synthesis and Processing is a comprehensive overview of the subject and is suitable for practitioners in the industry as well as those looking for an introduction to the field. It will be of interest to chemical, mechanical and ceramic engineers, materials scientists and chemists in both university and industrial environments working on or with refractory carbides, nitrides and borides.
