In the current study, crystal plasticity based finite element model is proposed to predict the flow stress behavior of the BCC α-Fe. The deformation behavior of the single crystal is predicted from crystal plasticity simulations and compared with experimental results on BCC α-Fe from the literature. Further, the flow stress behavior of polycrystalline BCC α-Fe is obtained using a simple four-grain model. Insights into interaction effects between grains due to different orientations on the global deformation behavior of bi-crystal are also presented. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
