| Abstract Scope |
Characterizing microstructure of metals is a necessary process in metallurgical manufacturing for determining material properties of an object. Spatially Resolved Acoustic Spectroscopy (SRAS) is a method for non-destructively characterizing microstructure providing similar information to that which you get from Electron Backscatter Diffraction (EBSD). The primary differences between these techniques come from the use of lasers and surface acoustic waves in SRAS vs electron diffraction in EBSD. SRAS has the advantages of being fully non-destructive, requiring little to no surface preparation, being performed in open air as opposed to vacuum, and being able to scan entire objects in a matter of hours. In this work we introduce the fundamentals of the technique and discuss improvements to established SRAS methodology using an array of instrumentation not currently discussed in the literature. These improvements in instrumentation are focused on improving the speed, resolution, and versatility of SRAS for applications in metallurgical manufacturing. |
