Ultrasonic Scattering from Voids and Inclusions in Model Polycrystalline Ceramics
Scattering of ultrasound from voids and inclusions in glass and cystallized glass is compared. The scatterers have diameters <100 μm. Crystallized glass has small crystallites which affect the sound field around a defect as the grains of a ceramic might. The effects of these crystallites on the sound field at the defect and at the water-sample interface is discussed.
