; ;
This paper presents recent correlations of nondestructive evaluation (NDE) and fractography results to establish the relative effectiveness of various NDE techniques in detecting and identifying failure-causing flaws in hot-pressed Si/sub 3/N/sub 4/. Ultrasonic and low-kV x-ray data are compared with fractography results by means of digital image-processing techniques.
