Summary

STEM and SANS analyses were used to identify and quantify microcracks and cavities that were produced during thermal cycling and creep tests on α-SiC, Si3N4, and ZrO2. The surface and internal defects thus characterized were related to specific failure modes at different temperatures and stresses.
