Abstract Scope |
Adequate experimental statistics is essential for improving and validating microstructural simulations to ensure the handshake between modelling and experiment. Here we present the next generation of lab-based diffraction contrast tomography (DCT), introducing advanced scanning schemes to seamlessly acquire data and reconstruct grain maps of longer, larger, high aspect ratio samples. This unlocks access to massive sample volumes – up to three orders of magnitude larger than traditional 3D-EBSD methods – and delivers true sample representivity. Additionally, due to its non-destructive operation, lab-based DCT enables tracking the evolution of microstructure through processes such as annealing or grain growth. The technique and examples will be presented highlighting the use of large volume, large grain statistics. |
