Abstract Scope |
Modern 3D characterization techniques acquire extremely high-fidelity microstructural data, but are often limited to small volumes with typically only hundreds of grains. This restricts analysis of extreme microstructural events crucial for understanding phenomena like material failure. This work presents an unprecedented 3D dataset of a single-phase Ti-7Al alloy, comprising roughly 520 mm3 and containing over 1 million grains. Collected using serial sectioning and computational polarized light microscopy, this dataset enables investigation of rare microstructural features and their influence on material properties. We discuss the experimental techniques used to collect this data set, the specialized analysis approaches built to process the voluminous amount of data, and the resulting statistical features of this extremely large polycrystalline aggregate. This large-scale dataset provides new opportunities for understanding microstructure-property relationships and advancing materials design. |
