Abstract	The effect of Re on stacking fault (SF) nucleation under shear strain in Ni is investigated using the climbing image nudged elastic band method with a Ni-Al-Re embedded-atom-method potential. A parameter (Delta E-sf(b)), the activation energy of SF nucleation under shear strain, is introduced to evaluate the effect of Re on SF nucleation under shear strain. Calculation results show that Delta E-sf(b) decreases with Re addition, which means that SF nucleation under shear strain in Ni may be enhanced by Re. The atomic structure observation shows that the decrease of Delta E-sf(b) may be due to the expansion of local structure around the Re atom when SF goes through the Re atom.
