Abstract

TiB₂-TiC composites were prepared using TiB₂ and TiC powders as starting materials by a floating zone (FZ) method in Ar atmosphere. TiB₂-TiC was a binary eutectic system with the eutectic composition of 28TiB₂-72TiC (mol%) and showed a laminar texture. The Vickers microhardness of TiB₂-TiC eutectic composite was 23 to 26 GPa. The electrical conductivity was 5.0 × 10⁵ to 1.6 × 10 ⁶ S m^{- 1} at room temperature and decreased with increasing temperature. The thermal conductivity was 30 to 45 W K^{- 1} m ^{- 1} at room temperature and slightly decreased with increasing temperature.
