A detailed X-ray Fourier line shape analysis has been performed on three compositions of Al–Zn alloys viz. Al–3 55 wt% Zn, Al–14 7 wt% Zn and Al–19 3 wt% Zn in
fcc phase. It has been found that deformation stacking faults, both intrinsic 𝛼' and extrinsic 𝛼'' are absent in the cold worked state and twin fault 𝛽 is found to be slightly present in the deformed lattice of the two initial compositions of the alloys. Similar to the effect of solute germanium and copper, respectively in Al–Ge and Al–Cu systems, hexagonal zinc also fails to impart faulting infcc Al–Zn system. This corroborates the fact that aluminium has high stacking fault energy.
