Webslip vector is close to (-1.0, 0.5, 0.5) which is actually the leading Shockley partials of>@211. So in fact, this part can be identified as Burgers vector of the leading Shockley partial dislocation. The slip vectors of atoms in the dislocation core are not in such good agreement with the expected full Burgers vectors.

(c) The Burgers vector of the Burgers circuit surrounding a … WebIn materials science, a partial dislocation is a decomposed form of dislocation that occurs within a crystalline material. An extended dislocation is a dislocation that has dissociated into a pair of partial dislocations. The vector sum of the Burgers vectors of the partial dislocations is the Burgers vector of the extended dislocation.
