| Abstract Scope |
Typically, many of the polycrystalline materials found in nature and those created using different manufacturing processes consist of multiple phases. Careful nondestructive characterization of these materials is of fundamental importance. The work presented here aims to provide a better understanding of the propagation and scattering of elastic waves in two-phase solids. Traditional ultrasonic theories are modified such that they can be applied to synthetic three-dimensional microstructures to determine the scattering responses numerically. Different volume fractions of the two-phase polycrystalline material of copper and iron (Cu-Fe) are considered for this study. DREAM.3D is used to simulate 30 realizations of synthetic microstructures representative of each volume fraction. Ultrasonic phase velocity and attenuation values are calculated for all the synthetic microstructures. The synthetic results are then compared with the microstructures of samples made from binary mixtures of pure copper and pure iron.
