Metallography of Consolidated Thermites

摘要

A process to press aluminum-copper oxide and aluminum-iron oxide thermites into strong, high-density composites for use as chemical heat sources has been developed. Metallography of the consolidated thermites and their reaction products required careful preparation in sectioning, grinding, and polishing because of the extreme differences in hardness between the metal matrix and the oxides. Using metallography as an analytical tool, consolidated thermites of uniform density and composition have been evaluated. (ERA citation 07:054465)
