Influence of microstructural morphology on ultrasonic scattering in polycrystalline media
Elastic wave scattering at grain boundaries in polycrystalline media can be quantified to determine microstructural properties. Attenuation and diffuse-field scattering events have been extensively studied, showing a clear dependence on both grain morphology and material texture (i.e., macroscale anisotropy). Models used to quantify scattering experiments are often developed under the assumption of equiaxed grains and a single effective grain diameter throughout the sample. In this dissertation, previous attenuation and single scattering response models are modified to account for grain elongation and grain size distributions. (Abstract shortened by ProQuest.)^
