METALURGY & PLASTICITY

Texture of metals is linked to specific physical properties, so the need to characterize it down to nanometer scale. Orientation and phase mapping with ASTAR technique of various steels , alloys and their corrosion products reveal their texture and help to understand their properties. Strain maps around thin layers and dislocations shed light to intrinsic material properties. The combination of ASTAR with 3D diffraction tomography enables to fully structurally characterize all main & secondary phases in steel and alloys.
