This book was released on 1991 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: MgAl\sb2Si\sb4O\sb6N\sb4$, and the matrix and reinforcing phases. The fracture toughness appeared to be controlled by the ability of cracks to propagate along the intergranular phase.

Book Properties of Silicon Carbide Fiber Reinforced Silicon Nitride Matrix Composites

Download or read book Properties of Silicon Carbide Fiber Reinforced Silicon Nitride Matrix Composites written by Ramakrishna T. Bhatt and published by . This book was released on 1988* with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical properties of NASA Lewis Research Center developed SiC/RBSN composites and their thermal and environmental stability have been studied. The composites consist of nearly 30 vol % of aligned 142 um diameter chemically vapor-deposited SiC fibers in a relatively porous silicon nitride matrix. In the as-fabricated condition, the unidirectional and two-dimensional composites exhibited metal-like stress-strain behavior, graceful failure, and showed improved properties when compared with unreinforced matrix of comparable density. Furthermore, the measured room temperature tensile properties were relatively independent of tested volume and were unaffected by artificial notches normal to the loading direction or by thermal shocking from temperatures up to 1100C. The four point bend strength data measured as a function of temperature to 1400C in air showed that as-fabricated strength was maintained to 1200C. At 1400C, however, nearly 15 percent loss in strength was observed. Measurement of room temperature tensile strength after 100 hr exposure at temperatures to 1400C in a nitrogen environment indicated no loss from the as-fabricated composite strength. (JES).

Book High Temperature Mechanical Behaviour of Ceramic Composites

Download or read book High Temperature Mechanical Behaviour of Ceramic Composites written by Karl Jakus and published by Elsevier. This book was released on 1995-06-28 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Mechanical Behavior of Ceramic Composites provides an up-to-date comprehensive coverage of the mechanical behavior of ceramic matrix composites at elevated temperatures. Topics include both short-term behavior (strength, fracture toughness and R-curve behavior) and long-term behavior (creep, creep-fatigue, delayed failure and lifetime). Emphasis is on a review of fundamentals and on the mechanics and mechanisms underlying properties. This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective. Shanti Nair is Associate Professor at the Department of Mechanical Engineering at the University of Massachusetts at Amherst. Karl Jakus is Professor at the University of Massachusetts at Amherst.

Book SYNTHESIS AND CHARACTERIZATION OF SILICON CARBIDE WHISKERS AND THEIR APPLICATION IN SILICON NITRIDE MATRIX COMPOSITES SILICON CARBIDE SILICON NITRIDE

Download or read book SYNTHESIS AND CHARACTERIZATION OF SILICON CARBIDE WHISKERS AND THEIR APPLICATION IN SILICON NITRIDE MATRIX COMPOSITES SILICON CARBIDE SILICON NITRIDE written by Liya Wang and published by . 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.

Book Effects of Interface Coating and Nitride Enhancing Additive on Properites of Hi Nicalon SiC Fiber Reinforced Reaction bonded Silicon Nitride Composites

Download or read book Effects of Interface Coating and Nitride Enhancing Additive on Properites of Hi Nicalon SiC Fiber Reinforced Reaction bonded Silicon Nitride Composites written by Ramakrishna T. Bhatt and published by . This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong and tough Hi-Nicalon SiC fiber reinforced reaction-bonded silicon nitride matirix composites (SiC/RBSN) have been fabricated by the fiber lay-up approach. Commercially available uncoated and PBN, PBN/Si-rich PBN, and BN/SiC coated SiC Hi-Nicalon fiber tows were used as reinforcement. The composites contained ~24 vol % of aligned 14 ♯m diameter SiC fibers in a porous RBSN matrix. Both one- and two-dimensional composites were characterized. The effects of interface coating composition, and the nitridation enhancing additive, NiO, on the room temperature physical, tensile, and interfacial shear strenght properties of SiC/RBSN matrix composites were evaluated. Results indicate that all three coated fibers, the thickness of the coating decreased from the outer periphery to the interior of the tows, and that from 10 to 30 percent of the fibers were not covered with the interface coating.
