| Abstract Scope |
Large scale microstructure statistics based on polished two-dimensional metallographic sections have been invaluable for describing microstructure correlations associated with deformation twinning. However, these 2D analyses cannot explicitly capture microstructure characteristics that are inherently three-dimensional, such as: individual grain/twin size and morphology, misorientation and boundary plane normal of grain boundary, twin domain facets, and full neighborhood effects. We have developed a new method for generating 3D datasets coupling polarized light microscopy (PML) with electron backscatter diffraction (EBSD) for 3D serial sectioning of ~mm3 volumes with ~300nm spatial resolution. In addition, we have developed a 3D graph theory based tool to analyze twinning statistics from these data sets and others such as 3D-EBSD generated using focused ion beam (FIB) based techniques. Based on these two capabilities, we will demonstrate 3D microstructure effects on deformation twinning in high-purity titanium. |
