Tracking the abnormal grain growth by LabDCT

Abnormal Grain Growth (AGG), where a small number of grains grow significantly faster than the surrounding microstructures, is a crucial concept in the study of polycrystalline materials because it can significantly impact their mechanical properties. In this study, we utilized laboratory x-ray diffraction contrast tomography (LabDCT) to collect 3D microstructural maps of high-purity Ni polycrystals before and after annealing and observed AGG. Thanks to the non-destructive nature of LabDCT, we were able to track the evolution of abnormal grains over time.
