| Abstract Scope |
With the emergence of a wide range of 3D characterization techniques, it is critical to understand the key differences in the fingerprint of a material’s microstructure when reconstructed in 2D and 3D. To this end, we performed a structural comparison of twin domain networks in high purity Ti using 3D and 2D electron backscatter diffraction. Insights into the topology of the networks are facilitated by combining statistical analysis of twin crystallography with a novel analysis of graph abstractions of the networks. We demonstrate that compared to 3D, conventional 2D views of twinning miss key aspects of the microstructure including the high interconnectivity of domains into scaffolds that span the full reconstruction volume. Critically, our study reveals that twin transmission and contact between different twin chains drives the high complexity observed in the network and plays a far greater role in network evolution, in comparison to isolated nucleation, than previously expected. |
