Book Description
In addition, the indentation crack healing and strength behavior of an Al2O3-SiC nanocomposite (Al2O3 + 5 vol% 0.2 mum SiC particles) has been studied as a function of crack size and the annealing environment. Results showed that annealing treatments can significantly increase the indentation strength. The annealing atmosphere was found to have a profound influence on the extent of crack healing and the degree of strength recovery. Annealing in argon resulted in a strength increase of 50%, whereas annealing in air yielded a 3-fold improvement in the indentation strength. SEM observation showed that healing of indentation cracks occurred in both environments, with the greater degree of healing taking place during annealing in air.

Book Description
Ceramic nanocomposites have been found to have improved hardness, strength, toughness and creep resistance compared to conventional ceramic matrix composites. Ceramic nanocomposites reviews the structure and properties of these nanocomposites as well as manufacturing and applications.Part one looks at the properties of different ceramic nanocomposites, including thermal shock resistance, flame retardancy, magnetic and optical properties as well as failure mechanisms. Part two deals with the different types of ceramic nanocomposites, including the use of ceramic particles in metal matrix composites, carbon nanotube-reinforced glass-ceramic matrix composites, high temperature superconducting ceramic nanocomposites and ceramic particle nanofluids. Part three details the processing of nanocomposites, including the mechanochemical synthesis of metallic–ceramic composite powders, sintering of ultrafine and nanosized ceramic and metallic particles and the surface treatment of carbon nanotubes using plasma technology. Part four explores the applications of ceramic nanocomposites in such areas as energy production and the biomedical field.With its distinguished editors and international team of expert contributors, Ceramic nanocomposites is a technical guide for professionals requiring knowledge of ceramic nanocomposites, and will also offer a deeper understanding of the subject for researchers and engineers within any field dealing with these materials. - Reviews the structure and properties of ceramic nanocomposites as well as their manufacturing and applications - Examines properties of different ceramic nanocomposites, as well as failure mechanisms - Details the processing of nanocomposites and explores the applications of ceramic nanocomposites in areas such as energy production and the biomedical field

Book Description
Increasingly stringent structural and electronic packaging requirements have exceeded the capabilities of traditionally used metallic materials in many applications. Metal matrix composites (MMCs) are potential replacements. Silicon-carbide particle-reinforced aluminum (SiCp/Al) is an attractive candidate because of its excellent mechanical properties, tailorable coefficient of thermal expansion (CTE) and high thermal conductivity. At present, there is very limited property data available for this material. This paper presents material properties of selected SiCp/Al composites, evaluated at the General Electric Astro Space Division, including a discussion of the test methods used in their evaluation.

Book Description
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.
