Modeling the micromechanical behaviors of Zircaloy-2 alloy under large deformation

The orientation distribution of grains (so-called texture) and its evolution almost decisively govern the in-service performance of a polycrystalline material, especially for materials with low crystallographic symmetry. As an important nuclear material, zirconium and its alloys have a hexagonal-close-packed (hcp) crystallographic structure and multiple plastic deformation mechanisms. Among them, deformation twinning, reorienting the basal …
