This presentation reports on an ongoing effort at Argonne National Laboratory to examine the correlation between NDE and fractography data obtained in Si3N4 containing seeded and naturally occurring flaws (Fe and Si inclusions, pores). Emphasis will be placed on the development of acoustic microscopy techniques for the detection of failure-initiating near-surface flaws in the tensile surface of modulus-of-rupture specimens. Fractography observations of failure-initiating flaw parameters and the attendant reduction in fracture strength will be discussed.
