Abstract

For clarification of the grain boundary energy and the structure of magnesium [11̄00] symmetric tilt boundaries, the atomic structure was obtained by molecular dynamics simulations. The results are summarized as follows. The grain boundary energy of [11̄00] symmetric tilt boundary depends on misorientation angle. There is a large energy cusp at the angle which corresponds to (112̄2) Σ11 symmetric tilt boundary. The boundary is one of the twins. It was found that (112̄4) Σ10 and (112̄2) Σ11 boundaries consist of single structural units, while (112̄6) Σ35b, (224̄6) Σ59 and (224̄2) Σ35a boundaries consist of two different structural units, respectively.
