ABSTRACT:
The invention relates to subjecting boron carbide to a heat treatment at a temperature within a range of 1250.degree. C. to less than 1800.degree. C. prior to infiltration with a molten metal such as aluminum. This method allows control of kinetics of metal infiltration and chemical reactions, size of reaction products and connectivity of B.sub.4 C grains and results in cermets having desired mechanical properties.
