A unique plastic deformation mechanism in penta-twinned Ag nanowires is revealed through a combined experimental-computational approach. The coherent twin boundaries within the nanowires lead to size-dependant nucleation controlled plasticity for which thiner nanowires are found to exhibit a remarkable combination of high strength and ductility accompanied by distributed plastically deformed regions along the nanowires composed of stacking fault decahedron chains.
