Microstructure Characterization


Microstructure Figure A majority of our ultrasonic scattering research is devoted to wave propagation through polycrystalline materials with various microstructures.

Material microstructure is more complex than grain size alone and we are developing models of the complete scattering process so that ultrasonic measurements can be used to quantify grain size, grain elongation, grain microstructure (i.e., duplex) and material texture.

These measurements can be used to quantify grain size, grain elongation, and material texture
