Microstructure of dual phase (DP) steel consists of a hard martensite island surrounded by soft ferrite. Since DP steel consists of two phases with a large difference in strength, it undergoes complex microstructure evolution during deformation. Therefore, an understanding of the evolution of microstructure during deformation is very important in the design and application of DP steel. In this study, a numerical analysis of uniaxial deformation of a DP steel was performed using a crystal plasticity finite element model. A representative volume element was reconstructed from the serially measured EBSD data. The material parameters of each phase were optimized by utilizing the results of nanoindentation and tensile tests. Meanwhile, in-situ EBSD measurement was performed to observe the microstructure during tensile deformation. The experimental and numerical results were quantitatively compared.
