Abstract:

Development of appropriate algorithms for fast and reliable creation of digital representations of dual phase (DP) microstructures is described in the paper. Modified Voronoi tessellation and cellular automata grain growth algorithms are described first to highlight difficulties in a realistic description of the DP morphology by artificial numerical approaches. To solve the presented limitations a modified Monte Carlo algorithm dedicated to creation of 2D and 3D virtual representations of DP steel is proposed. Details of the developed approach as well as examples of obtained results are presented within the work. Finally, obtained 3D digital representations of dual phase steel are subjected to numerical simulations of cold cube compression tests to investigate differences occurring in the two phases during plastic deformation.
