Modeling Texture Evolution of Pure FCC Alloy During Annealing

Abstract

During the annealing process of deformed materials, static recrystallization is an important phenomenon which can lead to significant texture changes in pure FCC alloy. In this paper, an integrated model was developed to describe the deformation and annealing process. The deformation process was firstly simulated in ABAQUS/Explicit, where crystal plasticity model was implemented into the FE package by developing the user subroutine. Then, a phase field model was proposed to simulate grain growth and texture evolution during annealing process. The outputs parameters of the deformation simulation, such as the orientation and deformation energy of each individual grain, were used as the inputs for phase field models. The nucleation of new grains was assumed to take place at grains which have the lowest deformation energy. This integrated model was applied to calculate the texture distribution of pure FCC sheet after annealing. The predicted texture distribution qualitatively matches the experimental results.
