| Abstract Scope |
Hexagonal closed-packed (HCP) metals have been extensively used in various industrial sectors. Understanding the deformation mechanisms of HCP metals at the grain-scale is a necessity for developing predictive models that can be used for the performance or failures analysis of engineering components. One of the common deformation mechanisms in HCP metals is deformation twinning. In this study, average grain stresses and size of the tensile twins are investigated with respect to their parent grains. In-situ three-dimensional X-ray diffraction (3D-XRD) is used for capturing grains center-of-masses (COMs), orientations, strains, and volumes. The evolution of stresses in twin and parent pairs are studied in detail, both at the early stages of plasticity and further into plastic zone. |
