X‐ray peak‐shift, peak‐asymmetry and peak‐broadening analyses were performed on cold‐worked α‐phase Ag‐Al alloys containing 5.8, 9.2, 15.8 or 18.2at %Al. A detailed analysis of the profiles revealed quantitative estimates of microstructural parameters including the dislocation density and stacking-fault energy. The results indicated an increase in the stacking-fault density, primarily of intrinsic character, with increasing solute concentration. These were mainly responsible for the observed peak shifts and domain size broadening. A small asymmetry in the profiles was found to be due to the presence of extrinsic stacking faults which were relatively less in magnitude as compared with intrinsic ones. Deformation twin faults were almost absent. The stacking-fault energy for pure silver was estimated to be 6 to 9mJ/m2; lower than previously reported values.
