Changes in Edislo-GB(d) and ΔE*(d); Edislo-GB(d) is the interaction energy between a screw dislocation and GB. ΔE*(d) is the change in potential energy due to GB-dislocation interaction and has the same units as the GB energy. Edislo-GB(d) of Σ7 (filled red circle), Σ37 (filled blue triangle), and Σ3 (filled orange square) are plotted on the left axis, and ΔE*(d) of Σ7 (open red circle), Σ37 (open blue triangle) and Σ3 (open orange square) are plotted on the right axis.
