Abstract : Alloying Cd, In, and Sn with Ag increases the density of stacking faults in these cold worked alloy filings with respect to pure Ag. Corresponding to the increase in stacking fault frequency as a function of alloying, there is a significant decrease in the effective particle sizes and the domain size in the plane of the stacking fault. Using the relative changes in lattice parameter calculated from the individual reflections, both deformation fault probability and lattice parameter of a deformed material can be determined. After cold working there was a detectable decrease in lattice parameter of the Sn but not the In alloys. Values of the faulting density obtained from asymmetry and peak maxima measurements were consistent with the ones obtained from anisotropic particle size measurements. (Author)
