| Abstract Scope |
Deformation twinning has been extensively studied as it plays a dominant role in the plastic deformation and strengthening in hexagonal closed packed (HCP) metals. Twin-twin interactions, twin-boundary interactions, and other characteristic features of twin networks have been studied extensively via electron backscatter diffraction (EBSD) in two dimensions (2D). However, the 2D characterization techniques fail to capture some of the important aspects of how three-dimensional neighborhoods influence twin network evolution. In this study, we utilized plasma-FIB (PFIB) based 3D-EBSD to capture the 3D evolution of twin networks in high-purity titanium compressed to several strain levels. Statistical analysis is performed to identify the characteristic features (e.g. twin chains, twin junctions) that govern the evolution of the 3D microstructure as a function of applied strain. One of the findings suggests that twin chain in 3D is much longer than we previously thought. |
