| Abstract Scope |
Many materials used in marine applications (e.g. nickel aluminum bronze, stainless steels) consist of multiple phases. Accurate nondestructive measurement of microstructure is essential because material properties and performance depend on it. In addition, new components created with material gradients must be verified. Ultrasonic scattering has shown promise for characterizing microstructural features such as grain size, orientation, phase fractions etc. This study focuses on numerically quantifying ultrasonic scattering from multiphase materials. DREAM.3D, a synthetic microstructure generation tool is used to create multiphase synthetic microstructures having different phases and different phase fractions. Traditional ultrasonic scattering models are used in a voxelized form for this purpose. Ultrasonic phase velocity, attenuation, and scattering for different measurement modes are calculated for all the synthetic microstructures. The results show the most sensitive measurements that can be used to estimate the microstructures of multiphase materials. |
