Compression and tension tests were performed on liquid-phase-sintered β-SiC fabricated by hot-pressing, using ultrafine powders, at 1973-2048 K in an N2 atmosphere. Amorphous phases were observed at the grain boundaries and at multigrain junctions in the as-sintered material. Strain hardening was observed under all experimental conditions. Stress exponents in the compression test were 1.7-2.1 in the temperature range 1973-2023 K. A maximum tensile elongation of 170% was achieved at the initial strain rate of 2×10-5 s-1 at 2048 K.
