- •
We provide in situ atomic-scale deformation process of Ag NWs (d < ∼10 nm).
- •
Plastic deformation mechanism of Ag NWs is different from high SF energy metal.
- •
There is a transition from extend dislocation to SF for [5
4] and [001] NWs.- •
There is a transition from full dislocation to {111} planes slip in [
11] NWs.- •
Plastic deformation is impacted by size, SF energy and loading direction.
