| Abstract Scope |
Additively manufactured parts often have microstructural textured regions (MTR). Quantification of these material regions is important because the properties are directly related to material deformation and overall longevity. Apart from defect detection, ultrasonic scattering has been used to characterize the microstructure of polycrystals. This numerical study is focused on predictions of microstructural textures and the related ultrasonic sensitivity to different microstructural textured regions. DREAM.3D is used to create synthetic microstructures having different cubic textures (cube, brass, goss) with a varying distribution width. Ultrasonic properties such as wave velocity, attenuation and backscatter are numerically calculated for all the synthetics using the discretized ultrasonic scattering model. The goal of this study is to determine optimum ultrasonic measurements to estimate microstructural textures. The findings of this study can be used to create experimental setups that can be implemented for in-situ characterization of additively manufactured cubic materials. |
