B 4 C-SiC-Si-TiB 2 composites were synthesized by a two step process. TiB 2 particles in the size range 2-5 m were generated in situ in the first step and were distributed in the residual silicon present in the reaction bonded boron carbide, in the second step. The composites were characterized by X
The formation and oxidation resistance of surface oxide layers formed on carbon-B&-Sic composites with two different B,C-SIC ratios were investigated at elevated temperatures in dry and moist atmospheres. From SEM observation, X-ray diffraction analysis, EPMA, and ESCA measurements of the samples b
