Sub-micrometer synchrotron tomography of multiphase metals using Kirkpatrick–Baez optics
High-resolution three-dimensional (3-D) imaging of heterogeneous metals was performed by high-energy magnified synchrotron tomography using Kirkpatrick–Baez focusing optics, achieving voxel sizes of (50–60 nm) 3. Holotomographic reconstructions were created based on absorption and phase contrast. Mi...

3. Holotomographic reconstructions were created based on absorption and phase contrast. Microstructural features as small as ∼180
nm were detected in ternary eutectic Al–Mg
2Si–Si, SiC-particle-reinforced AlCu4, near-β Ti–10V–2Fe–3Al, and in TiB-reinforced α

β Ti–6Al–4V. The phase-retrieval procedure yielded enough contrast to segment the individual phases and analyze their shapes and 3-D architecture. |
