A novel approach of the grain structure modelling in the framework of polycrystalline specimen and EBSD experiment simulation
Abstract
In this work the influence of the grain structure model in polycrystalline specimen on the results of the simulated EBSD experiment is studied. In the framework of EBSD experiment simulation the improved model of the polycrystalline with the grains in form of ellipses is used. Such a model is proposed to describe structural features of the real specimen more elaborately than one with grains as circles. Matching the improved polycrystalline model with the initial one is performed by comparison of the texture entities, restored from the EBSD measurements of specimens, with reference ones, calculated for modelled specimens. The EBSD experiment simulation is conducted for both specimens models under varying of the experiment parameters: a scanning step and a tolerance angle.
