A new method for computing grain boundary energies for arbitrary misorientation and inclination angles was proposed, based upon an atomistic approach (molecular statics) and using a semi-empirical atomic potential (2NN MEAM). The procedure was applied to the [110] symmetrical tilt boundary energy of pure Al. It was shown that the computed grain-boundary energy, and especially its misorientation dependence, were in good agreement with the experimental literature. The stacking-fault energy was calculated to be 141mJ/m2. Computation of Grain Boundary Energies. B.J.Lee, S.H.Choi: Modelling and Simulation in Materials Science and Engineering, 2004, 12[4], 621-32
