The processing and characterization of aluminum boride flake-reinforced aluminum matrix composites
AlB$\sb2$ flakes in an aluminum matrix offer the potential for greatly increased composite mechanical and wear properties because of their high aspect ratio, very high mechanical properties and good wetting to the aluminum matrix. This thesis describes, for the first time, an approach to the …

Temperature-dependent tensile and shear response of graphite/aluminum
… of unidirectional P100 graphite fiber/6061 aluminum matrix composites (v<sub>f</sub> = 0.47) was investigated at four temperatures: -150°F, +75°F, +250°F and +500°F, using test methods developed at Virginia Tech. Two types of tests, off-axis tension and Iosipescu shear, were used to obtain …

An investigation of the mechanical properties of warm rolled aluminum-17.5 weight percent copper alloy
An aluminum-17 . 5 weight percent copper alloy was warm rolled to achieve refinement of the microstructure . This refined microstructure consisted of finely dispersed intermetallic Al^Cu particles with an average size of 1.2 microns in an aluminum matrix. This led to improved room temperature …

Fabrication and Characterization of Aluminum Nano-Carbon Composites and Investigation of Their Electrical Conductivity
Incorporating nano-carbon phases into metal-matrix composites is a promising strategy for simultaneously enhancing electrical conductivity and mechanical properties of metals. Here, we describe the manufacture of novel nano-carbon-aluminum composites by an electro-charge-assisted process (EAP) that …

Recycling of aluminum scrap through direct Hot Rolling Process
Aluminum, with its unique blend of properties, has risen to become one the most abundant structural metal. In terms of industrial-scale production, it ranks second only to iron and steel. Aluminum can be produced from raw materials, referred to as primary aluminum, or by recycling scraps (secondary …

Evaluation of Arsenic and Selenium Quantitation in Marcellus Shales and Flowback Saline Waters using Thiol Cotton Fibre-Graphite Furnace Atomic Absorption Spectroscopy and Diffusive Gradient in Thin Film Techniques
… salinity aqueous media is difficult due to the matrix interferences which can either suppress or enhance the analyte signal. The objective of this proposed study has been to apply and/or modify inexpensive, simple, and interference-free analytical methods for the sub-ppb to ppb quantification of …
