In this study, a dislocation density based constitutive model with two phase, dislocation cell wall and cell interior, is proposed. Equations including twin volume fraction and twin thickness are added to consider not only slip but also twinning mechanism. In addition, incompatibility stress induced by insufficient slip system of hcp (hexagonal closest packing) structure material is also included. For the application of the model simple compression test of CP-titanium (grade 2) at various strain rate was performed and microstructure (specially, the evolution of twinning) were analyzed by optical microscope (OM) and electron backscatter diffraction (EBSD). Based on the parameters obtained by the test, the finite element method (FEM) simulation of the forging process with high pressure was compared with the experiment.
