| Abstract Scope |
Spatially Resolved Acoustic Spectroscopy (SRAS) is an emerging technology within the materials science community. Briefly, SRAS integrates state-of-the-art lasers, optical components, sensors, and other measurement devices to induce a surface acoustic wave (SAW) and record its position and velocity. Currently, these SAW maps can identify regions of microstructural variation, including local grain orientations. We have built upon the theoretical foundations of SRAS, and have developed a new algorithm to convert SAW data to quantitative orientation data and stiffness data. This approach enables obtaining orientation data outside conventional methods, such as electron backscatter diffraction, which is more constrained in build size and surface roughness than SRAS. Testing stiffness data from the built part allows stiffness tensor determination large, real parts, thus furthering the efforts to bridge the state-of-the-art in non-destructive evaluation with the state-of-the-art in advanced materials and processes in an industrially relevant way. |
