Advances in Nanocarbon Metals: Fine Structure

Abstract

This study is an investigation of the structure and some properties of silver, copper, and aluminum alloy covetics. Covetics can incorporate large amounts of carbon (C) in a nanoscale form to alter physical and mechanical properties of the base metal or alloy. Once the C has been incorporated into the matrix, it is highly stable and remains dispersed in the material after remelting and resolidification. Characterization of the thin film and bulk covetics was accomplished using X-ray diffraction, Raman spectroscopy, and transmission electron microscopy. Interesting property changes were detected for the different covetic materials. However, the samples always had nonuniformity of the C incorporation. Going forward, it is important to develop a method that will give rise to a more uniform distribution of the C so that a correlation between C content and properties can be obtained.
