Abstract
Ultrasonic attenuation has been measured for a range of ceramic polycrystals. An extreme‐value approach for attenuation analysis has been developed, based on numerical scattering cross sections and an extreme‐value characterization of the microstructure. A good correlation between predicted and measured attenuation has been obtained in each case. The implications of the analysis for ultrasonic failure prediction and microstructural characterization have been explored.Keywords
