Abstract

The compression and the tension tests of liquid-phase sintered β-SiC fabricated by hot-pressing using ultra fine powders were performed at 1973 K approx. 2048 K in N2 atmosphere. Amorphous phases were observed at the grain boundaries and at multi-grain junctions in the assintered material. Strain hardening was observed under all experimental conditions. Stress exponents in the compression test were from 1.7 to 2.1 in the temperature ranging from 1973 K to 2023 K. A maximum tensile elongation of 170% was achieved at the initial strain rate of 2 X 10-5 s-1 at 2048 K.
