Directionally reinforced B4C–TiB2 eutectic alloys were produced from green powder compacts by floating zone melting. Their mechanical properties were studied over a wide range of temperatures (25–1600°C). The high-temperature strength of the reinforced B4C–TiB2 composites hardly changes with increasing temperature and reaches about 200 MPa at 1600°C. Mechanical grinding and subsequent spark plasma sintering were used to produce reinforced B4C–TiB2 composites with an isotropic eutectic microstructure. The microstructure of the bulk-reinforced ceramic samples was examined. The developed ceramics meet the requirements imposed on high-temperature creepresistant and oxidation-resistant materials for reusable hypersonic vehicles.
