Abstract Scope |
Texture tomography is a recently developed framework for reconstructing three dimensional maps of the crystallographic texture of polycrystalline samples from scanning-beam experiments using synchrotron x-rays equivalent to X-ray diffraction computed tomography (XRD-CT) and scanning-beam x-ray diffraction (s3S-XRD).
Texture tomography is a compliment to these other techniques that works well for small-grained and textured samples, where the individual grains are not resolved by the experiment and for highly deformed microstructures where the grains are resolved but the process of peak-finding is difficult due to significant overlap of diffraction peaks from different grains.
We present the results of the first in-situ experiment using texture tomography to characterize a 3D-printed steel sample displaying twinning induced plasticity (TWIP). We obtain grain-maps from the bulk of the same sample at before and after deformation as well as measure the development of twinning. |
