Abstract Scope |
Metals are known to deform inhomogeneously. In this work multimodal X-ray tomography, i.e. attenuation tomography (ACT) and diffraction contrast tomography (LabDCT), was applied to study plastic deformation of a fully recrystallized Al-4mass%Cu alloy in 3D. Several correlations were examined between the 3D grain structure visualized by LabDCT and the local plastic strain distribution measured by a microstructural feature tracking (MFT) method based on ACT images before and after tensile deformation. The advantage and potentials of non-destructive 3D characterization of plastic deformation by the combination of laboratory X-ray ACT and MFT are discussed, the spatial resolution of the strain distribution measurements are quantified, and the observed microstructure-strain correlations are presented. |
