English abstract:
High resolution 3D imaging of heterogeneous metals is performed by high energy magnified synchrotron tomography using Kirkpatrick-Baez focusing optics achieving voxel sizes of (50-60 nm)³. Absorption and phase contrast are exploited applying holotomographic reconstructions. Microstructural features as small as ~ 180 nm are detected in ternary eutectic Al-Mg2Si-Si, SiC particle reinforced AlCu4, near b Ti-10V-2Fe-3Al, and in TiB reinforced a+b Ti-6Al-4V. The phase retrieval procedure yields enough contrast to segment the individual phases and analyze their shapes and 3D architecture.
