  "abstract": "Defect–grain boundary interactions have been proven essential for the development of tailored microstructures for high-performance materials. We aim to unravel the mechanical response of grain boundaries by investigating dislocation activity in the vicinity of a tensile twin boundary (TB) in Mg–Y. A combined approach of quasi in-situ nanoindentation, electron channeling contrast imaging (ECCI), and HR-EBSD was employed to induce localized deformation and analyze the resulting TB response. Indentation in the parent grain near the TB produced distinct pop-ins, indicating deformation events close to the boundary. Observed slip included non-basal activity in the twin and prismatic slip in the parent grain. Dislocation pile-ups caused TB bulging rather than transmission, consistent with low slip transmission factors. However, limited slip transmission is observed. Peach–Koehler force calculations based on HR-EBSD measurements confirm stress-induced TB motion.",
