In the original publication of the article, Eqs. (2) and (3) are provided in the incorrect form. The corresponding correct equations are provided below.
Equation 2
The resulting force acting on the dislocation line is given by the Peach–Koehler equation (Peach and Koehler 1950):
where F l is a force acting on a unit length of a dislocation line l; σ is the applied stress tensor resulting from straining the cell and b is the Burgers vector.
Equation 3
Accounting for a change in dissociation width R in various metastable configurations with respect to that in the stable dislocation core, the associated energy increase ∆W should scale with the following expression (Hirth and Lothe 1982):
where ∆W/L is the increase in energy per dislocation unit length with respect to the equilibrium configuration characterized by a dissociation width \( R_{\text{SF}}^{\text{eq}} ; \) R SF is the extension of a perfect stacking fault between the two partials; µ is the anisotropic shear modulus; ν is the Poisson ratio; b i and l i are the partial Burgers vectors and the dislocation line vectors, respectively.
