Ab initio calculations of the generalized stacking fault energy in aluminium alloys
M. Muzyk , Zbigniew Pakieła , K.J. Kurzydlowski
AbstractThe generalized stacking fault energy for aluminium and some of its alloys have been calculated using density functional theory. It is shown that the deformation tendency caused by emission of partial dislocations varies with alloying element. The twinnability of aluminium is also modified by the presence of alloying element in the deformation plane. The results suggest that Al–Mg and Al–Ga alloys are the most susceptible for the deformation by partial dislocations and twining.
