| Abstract Scope |
Polycrystalline materials exhibit properties that are directly influenced by the morphology and crystallographic orientation of their constituent grains. In this work, we interrogate the 3D grain morphology and texture of polycrystalline materials (such as alpha titanium) via polarized light microscopy (PLM) within an automated serial-sectioning system. PLM leverages optical birefringence in anisotropic/uniaxial crystalline materials to assess crystal inclination relative to the incident polarized light beam, resulting in image contrast that reveals grain orientation. We introduce data processing and reconstruction techniques to rapidly determine the grain morphology and crystallographic texture in centimeter-scale volumes. Details of implementation and novel approaches to analysis will be presented. Applications to macroscale texture quantification and understanding mechanical properties in lower-symmetry and multi-phase systems will also be discussed. |
