Summary

SiC-polycrystalline fiber-bonded ceramics (SA-Tyrannohex™) showed good fracture energy, high-temperature capability, very excellent thermal conductivity and low density. The fracture strength of the notched SA-Tyrannohex at room temperature was described fairly well by the net stress criterion. This result indicates that SA-Tyrannohex is not sensitive to the notch and can be used safely. SA-Tyrannohex with post heat treatment in air showed an excellent oxidized-resistance at the wide temperature ranges from 800°C to 1500°C. And the initial high strength of SA-Tyrannohex at room temperature was preserved even at 1500°C. The relatively high yielding point (about 130MPa) of SA-Tyrannohex were maintained up to 1500°C.
