Book Processing Microstructure and Mechanical Properties of Silicon Carbide Particulate Reinforced Aluminum Alloys

Download or read book Processing Microstructure and Mechanical Properties of Silicon Carbide Particulate Reinforced Aluminum Alloys written by Chikara Fujiwara and published by . This book was released on 1988 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: SiC particulate reinforced A1-2%Mg composites were produced at volume fractions 0.1, 0.2, and 0.3 by inert atmosphere ball milling followed by Hot Isostatic Pressing consolidation and extrusion. The SiC particulate sizes evaluated were 5 microns, 1 micron, and 0.2 microns. The processing sequences were carefully controlled to minimize oxygen contamination. The resulting microstructures of the as-extruded materials showed a very uniform distribution of particulates within the matrix. Ultimate strength, 0.2% yield strength, and modulus of elasticity increased with decreasing SiC particulate size: 1 micron SiC-A1 matrix showed the highest elongation. Fractures originated at inclusions rich in iron, chromium, and nickel. These contaminants seemed to come from the mill chamber and/or the hardened steel balls during ball milling. Keywords: Silicon carbide, Composites, Ball milling, Microstructure.

Book Dispersion and Blending of SiC Silicon Carbide Whiskers in RSP Aluminum Powders

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.

Book Structural Ceramics

Download or read book Structural Ceramics written by John Jr. Wachtman and published by Elsevier. This book was released on 2012-12-02 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Materials Science and Technology, Volume 29: Structural Ceramics presents an overview of structural ceramics. This book begins with a survey of potential uses, designs, and barriers of particular types of structural ceramics. The silicon carbide family, silicon nitride and sialon family, and transformation toughened ceramics are discussed in detail, followed by an analysis of the various processing routes of each family of structural ceramics. This publication concludes with a review of the tribology of structural ceramics, considering many applications for structural ceramics in heat engines and other machinery that involve moving parts which must often resist wear or erosion. This volume is recommended for engineers, scientists, and researchers concerned with structural ceramics.

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Users of this work can improve their knowledge of basic principles and gain a better understanding of process/structure/property relationships. With the convergence of nanotechnology, coating techniques, and functionally graded materials to the cognitive science of cemented carbides, cermets, advanced ceramics, super-hard materials and composites, it is evident that the full potential of this class of materials is far from exhausted. This work unites these important areas of research and will provide useful insights to users through its extensive cross-referencing and thematic presentation. To link academic to industrial usage of hard materials and vice versa, this work deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds.

Book Processing and Characterization of Zirconium Dioxide Dispersion Strengthened Al7068 Composites

Download or read book Processing and Characterization of Zirconium Dioxide Dispersion Strengthened Al7068 Composites written by Madhusudhan Mariswamy and published by . This book was released on 2018 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum metal matrix composites are a class of advanced engineering materials that have major applications in aerospace, automobile, and marine engineering domains because of their mechanical properties. The aluminum matrix is dispersion strengthened with hard ceramic particles like zirconia (ZrO2), silicon carbide, alumina, boron carbide, and so forth bringing about better wear protection and enhanced strength-to-weight ratios. In light of the advances in the size and morphology of the reinforcements, it is indeed a sensitive task to process the aluminum composite materials. Among the various processing methodologies, the traditional stir casting technique is an important fabrication methodology for delivering aluminum matrix composites, since it is generally reasonable and offers an extensive variety of material processing conditions. An endeavor has been made to manufacture Aluminum Matrix Composites (AMCs) with the Al7068 alloy as the matrix phase and ZrO2of a generalized particulate size of 25-40 ?m as the reinforcement phase dispersed with varying weight proportions in the range of 0 to 12 wt. % in intervals of 2 wt. % utilizing an indigenously created stir casting process. The homogeneous scattering of ZrO2 particles in the AMCs is distinctly observed from the optical micrographs. Mechanical characterization is effectively done, and the tensile, compression, hardness properties of the composites are taken into account, which gives major evidence that the characteristics of the AMCs improve with the addition of reinforcement particulates attributed to the fact that ZrO2 forms a solid solution with the Al7068 eutectic phases, resulting in improved densification and better toughness and load-bearing capabilities.
