X-ray Imaging
Division 8.5
The X-ray Imaging division is your point of contact for non-destructive three-dimensional testing of components using X-rays.
We offer a unique palette of experimental techniques to characterize the micro- and meso-structures over a large spectrum of materials (light alloys, steels and superalloys, ceramics, composites).
We focus on the microstructure-property relationships, linking the 2D and 3D quantitative analysis of defects and internal features to stress distributions and phase-specific mechanical properties.
We use simulation and analysis tools that support the interpretation of our experimental data. We continuously develop solutions for quantitative microstructural analysis. Finally, we offer comprehensive service to industry and academic partners.
