Book Description
A technique was developed for orienting silicon carbide whiskers in a metal matrix which involves the preparation of a liquid slurry of the whiskers and matrix metal powder followed by the extrusion of the slurry through a fine orifice die. The technique was further developed for the fabrication of aluminum alloy-silicon carbide whisker composites with oriented whiskers. The fabrication of such shapes as strip, tubes, bushings, and cones with oriented whiskers was demonstrated. Mechanical properties of the aluminum alloy-silicon carbide whisker composites were measured at room temperature and at 204 to 427C. The effect of silicon carbide whisker loading, whisker type, and metal powder particle size was studied. (Author).

Book Description
This program deals with determining factors that influence strength, ductility, fracture toughness, and elongation to failure in Silicon Carbon Whisker/Aluminum alloy composites. Specifically, a microstructural study is being made in an attempt to define extrinsic and intrinsic factors that control fracture and thus influence properties. One of the more important products produced by ACMC from SiCw/Al composites has been the rolled sheet. The response of the material to secondary processing and thermo-mechanical treatment is of utmost importance with respect to material quality. The present study emphasizes microstructural-mechanical property characterization of the rolled material (JES).

Book Description
A compilation of data collected and maintained for many years as the property of a large aluminum company, which decided in 1997 to make it available to other engineers and materials specialists. In tabular form, presents data on the tensile and creep properties of eight species of wrought alloys and five species of cast alloys in the various shapes used in applications. Then looks at the fatigue data for several alloys under a range of conditions and loads. The data represent the typical or average findings, and though some were developed years ago, the collection is the largest and most detailed available. There is no index.

Book Description
`Metal-Matrix Composites' are being used or considered for use in a variety of applications in the automotive, aerospace and sporting goods industries. This book contains sixteen chapters, all written by leading experts in the filed, which focus on the processing, microstructure and characterization, mechanics and micromechanics of deformation, mechanics and micromechanics of damage and fracture, and practical applications of a wide variety of metal composites.A particularly noteworthy feature of this authoritative volume is its collection of state-of-the-art reviews of the relationships among processing, microstructural evolution, micromechanics of deformation and overall mechanical response.

Book Description
The effects of mechanical working on SiC whisker-reinforced aluminum alloys were investigated. The effects of pressing, extruding, and rolling on whisker dispersion, L/D ratio, and orientation were determined by examination of polished cross sections using conventional optical microscopy and by examination of replicas with a transmission electron microscope. These results were correlated with the mechanical properties of the composite. It was found that mechanical working of the composites significantly degrades the whiskers, particularly the L/D ratio. Extrusion and rolling, however, do impart an orientation to the whiskers in the direction of working. It was also found that clumping observed in the unworked billets is carried through both the extrusion process and rolling. These SiC-rich areas apparently lead to the formation of porosity in the composites during working. The high level of mechanical properties found in the worked composites suggests that optimization of the secondary working parameters (in such a manner as to minimize whisker damage) may result in the realization of a truly unique structural material.
