Book excerpt: A method of growing silicon carbide whiskers, especially in the .beta. form, using a heating schedule wherein the temperature of the atmosphere in the growth zone of a furnace is first heated to or beyond the growth temperature and then is cooled to or below the growth temperature to induce nucleation of whiskers at catalyst sites at a desired point in time which results in the selection.

This book was released on 19?? with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beta silicon carbide whiskers in the form of long staple wool (1 - 10 microns diameter by 1/2 in. 1 in. length) have been grown by flowing a H2, CO, CH4, and N2 gas mixture through a reactor containing a silica source, and five pounds of the output whisker product have been delivered. Growth studies have been made in the temperature range of 2300 to 2800F in growth times ranging from 4 to 24 hours. The reactor consisted of a 20 KW furnace containing a quartz muffle. Gas composition, collector geometry, and materials have been studied to enhance the type and quantity of silicon carbide wool produced. The whiskers appear to grow by a vapor-liquid-solid mechanism. The wool formed has a cotton-like texture and is amenable to forming into yarns. The wool varies in color from buff to dark green presumably because of trace impurities. The whiskers are triangular in cross section and X-ray analysis has identified the material as beta silicon carbide. Tensile tests on the product have measured average rupture strengths in excess of one million psi and elastic modulus in the range of 92-95 million psi. Engineering design and scale-up studies at the level of 100 pounds per year of whisker wool have been conducted in a furnace with a 15-foot growth zone designed.

Download or read book Dispersion and Blending of SiC Silicon Carbide Whiskers in RSP Aluminum Powders written by and published by . This book was released on 1986 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal matrix composites (MMC's) of research quality are required to establish reliable relationships between material properties, composition, and processing parameters. Systematic variation of composition and consolidation parameters is necessary to determine their effect on composite mechanical and physical properties. To address the problems of material availability, lack of control of material processing parameters, and nonuniform whisker distribution, a program was instituted to develop a technique for producing a uniform blend of metal powders and whiskers for subsequent consolidation and characterization. An ultrasonic method has been developed for separating silicon carbide (SiC) whiskers in the clusters which are typically found in the as-received SiC whiskers made from rice hulls. The method has also been used to disperse the whiskers uniformly in a -325 mesh rapidly solidified (RSP) aluminum powder. Scanning electron microscopic examination of the separated whiskers and the whisker/aluminum powder blend indicate that the whiskers retain a high length to diameter ratio after processing. Fully dense compacts produced by hot isostatic pressing of the blend exhibit a uniform whisker distribution.

This book was released on 1989 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon carbide whiskers have excellent mechanical and chemical properties, making them very desirable as a reinforcement for structural ceramic and other composite materials. Los Alamos has developed a laboratory-scale batch process for producing very high quality SiC whiskers by the vapor-liquid-solid (VLS) method which is an active candidate for technology transfer involving significant scale-up. The process, however, involves quite complex chemical/physical and parametric relationships and has not as yet lent itself successfully to modeling. An expert computer system was therefore developed to facilitate the transfer of this technology to industry. Optimum conditions were determined by relating the many process parameters to product results to establish a set of rules for running the process. These are incorporated in a two-phase expert system designed to guide inexperienced users. In Phase 1, an expert consultant program provides the user with information that enables him to set up the run. This information is incorporated into the rule base that makes up Phase 2 -- the control system. At present, the operator functions as the controller by responding to the decisions of the expert system; automation can be added later. 13 refs., 16 figs.

This book was released on 2011-04-04 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we explore an eclectic mix of articles that highlight some new potential applications of SiC and different ways to achieve specific properties. Some articles describe well-established processing methods, while others highlight phase equilibria or machining methods. A resurgence of interest in the structural arena is evident, while new ways to utilize the interesting electromagnetic properties of SiC continue to increase.
