摘要	Dislocations < 1 1 0 >/2 are usually dissociated into two < 1 1 2 >/6 partials with a stacking fault in face centered cubic metals. Their behavior depends strongly on the stacking fault width (SFW) in plastic deformation. However, there is no quantitative study to correlate the SFW with the dislocation configuration when these dislocations are grouped together. In this work, the SFW for different dislocation arrays is analyzed within the framework of the elasticity theory of dislocations and then verified by atomistic simulations. The results demonstrate that the spacing of dislocation arrays has to be taken into account for the SFW variation besides the dislocation character. In addition, the SFW variation with the dislocation spacing seems to be independent to temperature. Our approach can also provide a basis for the accurate estimate of the influence of stacking faults on cross-slip, the competition between slip and twinning during plastic deformations in face centered cubic metals.
