Microtexture tracking in hot-deformed polycrystalline aluminium: Experimental results

Optimal polyhedral description of 3D polycrystals: Method and application to statistical and synchrotron X-ray diffraction data

“…This is at the expense of morphology simplification (as opposed to direct meshing [27,28]); however, for the materials under investigation, a good agreement was obtained with an intersection rate of about 90%, comparable to experimental uncertainties. This level of agreement would somewhat drop for more complex (non-convex) grain shapes as those generally encountered in more highly alloyed metals [57]. Another advantage of the present method is that the tessellations are the best convex, Laguerre-type approximations of the polycrystal, which can be seen as "cleaned up" descriptors that can be meshed with higher control on element size [26].…”

“…Other, destructive techniques combine optical or electron microscopy to serial sectioning [49,54,55]. Of course, 2D-only characterizations are also often used [56,57]. All of these techniques provide raster images, i.e.…”

Deformation-induced orientation spread in individual bulk grains of an interstitial-free steel

“…The presently characterised intragranular orientation spread extends over 3-5. It therefore corresponds to the long-range orientation gradients generally observed by EBSD [60,61] and also obtained from finite-element-based [62,63] and fast-Fourier-transformation-based [64] crystal plasticity simulations. In particular, the 3-5 intragranular orientation spread found in the present study compares with a 2-4 value reported in the finite element study of misorientation evolution by Dawson et al [62].…”

A method to correct coordinate distortion in EBSD maps

“…With EBSD, individual grain orientations, local texture, and point-to-point orientation relationships can be determined routinely on the surfaces of bulk samples. In the last decade this technique has frequently been used for in-situ and ex-situ studies, from which dynamic information of microstructural evolution during thermal-mechanical processing has been reported [4][5][6][7][8][9][10].…”
