This book was released on 1993 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A centrifugally cast A356 aluminum-matrix composite reinforced with silicon carbide (SiC) particles was thermo-mechanically processed by rolling and the resulting properties were studied. Tensile testing, hardness testing and optical microscopy were conducted. This study included evaluations of the mechanical properties of the composite following rolling at varying strains, temperature, strain per pass and aging treatments. The effects of both single and multi-step rolling processes were evaluated, and the composites were tested following solution treatment. Testing revealed that the ductility was associated with progressive homogenization of the particulate distribution at increasing strain levels. It was found that rolling just under the solvus temperature produced poorer mechanical properties for the composite than for those rolled at a temperature significantly above or below the solvus temperature. Strain per pass was found to have insignificant effect on the final properties, with total strain being the controlling factor. For equal strength conditions, the underaged composite was more ductile than the overaged composite.

This book was released on 2012-12-06 with total page 427 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 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination 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 concerned if the printing and distribution of the volumes were handled by an international 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 Corporation 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 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 1996-06-01 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discontinuous reinforced aluminum (DRA) composites are attractive as structural materials because of their desirable stiffness and strength to weight ratios and relative ease of manufacture. However, they typically display low tensile ductility and fracture toughness. In this work, the impact of post- fabrication deformation processing and heat treatment on the fracture properties of a 17.5 vol. % SiCsubp reinforced Al 6092 matrix composite is investigated. Process temperature, total strain and strain rate during extrusion were varied in order to explore the feasibility of obtaining Particle Stimulated Nucleation (PSN) of recrystallization during processing, with the goal of refining the matrix grain size. Additionally, various combinations of solution and aging treatments were investigated with the aim of obtaining a number of stable matrix microstructural conditions with varying levels of composite strength and fracture toughness. A preliminary investigation of fracture mechanisms and their dependence on the matrix aging state has also been carried out using optical and scanning electron microscopy (SEM) and differential scanning calorimetry (DSC), and is reported here.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal Matrix Composites (MMCs) are now attracting enormous interest, because of their superiority in strength, stiffness, wear resistance, elevated temperature strength or other engineering properties. Parallel to commercialisation, there are research centres throughout the world that are actively researching further development and exploitation of net or near net shape fabrication process. In this book, the production and characterisation of SiC particles reinforced Al alloy matrix composites produced by squeeze casting are investigated. The effects of volume fraction of SiC on microstructure, mechanical properties are examined as well.

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.
