Properties and Texture Evolution of DD6 Single Crystal Alloy Based on CPFEM
The crystal plasticity finite element method(CPFEM)was employed to investigate mechanical properties of DD6 single crystal alloy under high temperature conditions.The results indicate that under certain loading rates,the(223)[110]orientation exhibits the highest yield stress and elastic modulus among different orientations.The activation levels of different slip systems also vary for different orientations,resulting in different values of maximum accumulated shear strain.Grains with all orientations suffer grain rotation,where the(001)[110]orientation exhibits the largest deviation angle.Under the constant orientation condition,strain rate has little influence on the elastic modulus,while the yield stress shows a positive correlation with strain rate.
