摘要

Crack healing in liquid-phase-pressureless-sintered SiC-AIN composites was investigated by introducing cracks into specimens and subsequently heat-treating the specimens. It was observed that cracks were healed and the strength was recovered. Cracks were filled with silica or mullite produced by the oxidation of the composites. It was shown that the healing temperature could be fixed in the range 1100-1300 °C and that large cracks up to about 300 mu m could be healed completely. Our results imply that a simple oxidation heat-treatment can improve the reliability of silicon carbide-aluminum nitride components.
