Figure 6: Mono-segregation behavior of (a) Ca, (b) Zn and (c) Al solutes at the dislocation. Upper row: Atomistic simulations; lower row: Interaction energy fields between the solute modeled as an elastic dipole and the strain field of the dislocation. A negative value of ΔEseg indicates that segregation is energetically favorable. (d) Distribution of ΔEseg for Ca, Zn and Al solutes with data grouped into bins of 2 meV. (e) Statistics of ΔEseg as a function of distance to the center of the dislocation core. Negative distances correspond to the tensile stress region, whereas positive distances indicate the compressive stress region. Data is divided into bins of 2 Å.
