mechanism; Zr alloy; EBSD; crystal plasticity; plastic deformation 1 Introduction Zr alloys are widely used in nuclear reactors because of their excellent mechanical properties, good corrosion resistance... slip and twinning modes are critical inputs in crystal plasticity models in order to accurately predict the deformation behavior. The previous review showed that the CRSS values strongly depend......
