| Research Abstract |
We developed a new numerical simulation method by combining the crystal plasticity finite element method, the GPU-accelerated multi-phase-field method and the homogenization method in order to predict microstructure formations and mechanical properties of high strength multiphase steels, such as dual-phase (DP) steel. In this study, using the developed method, we systematically investigated the austenite-to-ferrite transformation from the hot-deformed austenite phase and the uniaxial tensile deformation behavior of the DP steel on the basis of the microstructural morphology simulated by the multi-phase-field method.
