| Popis: | The topic of reconstruction of polycrystalline microstructures is briefly reviewed. An example is given of using orientation maps to reconstruct digital microstructures with a representation of a polycrystal structure that includes crystallographic orientation information. The method uses packing of ellipsoids to approximate the grain structure, coupled with Voronoi tessellation. For the example of hot rolled commercial purity aluminum that was chosen, the highly elongated grain shapes required stretching of the tessellation in order to match the observed aspect ratios. |
