Abstract

The energies of deformation fault (I2) and twin-like fault (T2) of thirteen binary Mg alloys were studied using density functional theory. It is shown that the faulted regions are energetically favorable for solute segregation, and the reduction of stacking-fault energy (SFE) was caused by charge redistribution. We define a charge redistribution factor, F, to quantify the solute-induced charge redistribution. An analytical model was established to calculate SFE from F.
