## Description

- description: Synchrotron X-ray multiscale tomography is a 3D imaging technique that
    integrates microtomography and nanotomography, enabling high spatial resolution
    analysis across a broad field of view. This approach allows for tracking 3D microstructural
    changes at multiple length scales in processes such as powder compaction, sintering,
    and ceramic microfracture. The heterogeneity, complexity, diversity, and hierarchical
    nature of powder compacts give rise to various defect types that influence product
    quality, reliability, and lifespan. In spark plasma sintering, defect formation
    and elimination are influenced by applied external stress, while internal stresses
    generated during differential and constrained sintering also play a critical role.
    Furthermore, the intricate subsurface crack networks formed by Vickers indentation
    highlight how heterogeneous microstructures contribute to toughening mechanisms.
