Summary

Composites have been prepared by the directed reaction of a liquid metal with boron carbide to yield platelet-reinforced carbide matrix materials. Dense bodies with less than 1% porosity in sizes up to 8 in. in diameter and 1-2 in. thick have been prepared to near net shape. The preparation and processing of these materials are discussed with specific examples in the zirconium system. The observed microstructures of these materials are also presented together with a discussion of methods for tailoring the microstructure, and thus the properties, of the composite by varying the processing conditions.
