摘要：

The generalized stacking fault energies of magnesium and their alloys have been calculated using density functional theory. It is shown that the deformation tendency caused by partial dislocations emission varies with alloying elements. Three slip systems have been considered: (0001)[1120], {1 (1) over bar 00}[(1) over bar(1) over bar 20] and (0001)[1100]. It has been shown that Pb and Sn strongly change the generalized stacking fault energy of Mg, thus reducing the stacking fault energy. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd.
