▼a When an ultrasonic wave propagates in polycrystalline materials, the wave is scattered on grain boundaries and the scattered waves carry important information on material microstructure, e.g. grain size and texture. Using grain scattering inform |

▼a One objective of this dissertation is to provide a better understanding of ultrasonic propagation and scattering in textured polycrystyals. In this dissertation, general attenuation and scattering models are developed for polycrystals with arbit |

▼a The second major objective is to ultrasonically characterize the microtextured regions (MTRs) in Ti alloys which is a result of orientation clustering of crystallites and leads to a reduction of dwell fatigue properties of the material. The mode |

▼a The third objective of this dissertation is to establish an inversion methodology to robustly reconstruct material characteristics from ultrasonic attenuation and backscattering measurements. By using a combination of the attenuation-to-backscat |

▼a The experimental methodology and the system calibration method are described for the near field of the ultrasonic transducer measurements. Examples of measurements and application of inversion models to typical titanium alloy samples are given. |
