Microstructural Characterization of a Proprietary Ceramic Armor.
Abstract
As-polished and polished-and-etched sections of a proprietary ceramic armor material were examined by light microscopy in an effort to characterize the microstructure. Regions representing the bulk of the material and random volumes of low X-ray radiographic density were studied. Silicon, silicon carbide, and boron carbide were identified in the bulk of the material whereas titanium monoboride and silicon triboride, in addition to the aforementioned components, were found in the volume of low radiographic density. All of these components could be differentiated in the unetched condition. It is apparent that liquid silicon reacts with boron carbide to form silicon carbide. The latter tends to be transparent. It is suggested that the presence of titanium in the form of TiB is responsible for the low radiographic density. (Author)
