Characterizing polycrystalline microstructures by reconstructing grain boundaries and velocity map from ultrasonic surface wave field
An ultrasonic material characterization method is proposed to reconstruct the polycrystalline microstructures from the field-measurement of ultrasonic surface waves. Two wavenumber-frequency domain filters are developed to extract specific wave components for the reconstructions. One is the evanesce...
