| Abstract Scope |
The acquisition of high-fidelity 3D grain maps is essential for advancing our understanding of the micromechanical behavior of polycrystalline materials. Grain orientations, grain boundary misorientations, and grain shapes play a significant role in important phenomena such as slip transfer, corrosion, and grain growth. The past few years have seen considerable advances in the acquisition of high-reliability grain maps using laboratory-based Diffraction Contrast Tomography (LabDCT). Additionally, the microstructures of challenging sample geometries have become more accessible at the lab scale with recent developments in advanced Lab DCT acquisition strategies, such as helical phyllotaxis scanning and forward-based reconstruction. In this paper, we present the state-on-the-art of lab-scale DCT. The important strides over the years as well as challenges and opportunities will be presented. The use of machine-learning based techniques for rapid acquisition and high throughput will be discussed. |
