Abstract
The development of a database for the ultrasonic NDE of advanced-ceramic components is described. High frequency (≤100 MHz), high power transducer development was involved and the probes are used to examine model spherical inclusions (voids (≥20 μm), ZrO2, MgO, V2O5 and Pt inclusions (≥30 μm)) in model matrices (glass, crystallized glass and partially stabilized zirconia). Actual frequency spectra obtained from these defects as a function of defect size are compared with their calculated spectra based on scattering theory and very good agreement is obtained.
