Our work is aimed to investigate the deformation behavior of Ag‐17vol.%SnO2 metal matrix composites under a hot extrusion process which causes extraordinarily large plastic deformations and recrystallization. The micro‐macro integrated axisymmetric finite element simulation is preferred for the first study, since it costs less calculation effort compared to 3D calculations, presents the mechanical variables in all 3D dimensions and the measured microstructure can be directly applied as the cross section. Due to that the volume (area) fraction of the particle phase in the selected 2D real microstructures often deviate from the real one, we show a numerical method to modify the EBSD‐images in order to match the 3D composition. This modification should be useful for FE simulations with a geometry based on a real microstructure. Considering that the tomograms are actually 2D images with a given distance in the 3rd dimension, such a modification with a further extension in the algorithm can also be applied for 3D microstructures based on tomograms to match the real composition.
