Abstract
We applied the crystal plasticity finite element method (CPFEM) based on a rate sensitivity model to examine the subgrain texture evolution of FCC metals under shear deformation. We used two kinds of microstructure models with the same orientation distribution function (ODF) but different spatial arrangements or misorientation distributions (MDs). One contained a great high frequency around low misorientation angles and the other a great high frequency near high misorientation angles. Different misorientation angles among neighboring crystals caused different interactions among them, particularly at the subgrain scale. The difference in MD affected the evolution of texture and average misorientation angles during deformation. The average misorientation angles of the subgrain boundaries increased with shear strain.
