The stacking fault probabilities and lattice spacings of silver-rich Ag−Pd−Cd alloys

  • S. K. Rhee


The deformation stacking fault parameter, α, has been determined from X-ray peak shift measurements on filings of silver-rich Ag−Pd−Cd solid solutions. In the Ag−Cd binary alloys, α increases exponentially with the cadmium content, from 3×10−3 for pure silver to 19×10−3 for 80Ag−20Cd. As palladium is added to the Ag−Cd binary alloy, α decreases in such a manner that the effect of cadmium is counter-balanced by palladium until both are present in equal proportions and, thereafter, α remains constant. The results are compared with previous determinations on other binary alloys. The lattice parameter,a, also has been measured on annealed samples.a increases linearly with cadmium up to 20 at. pct Cd. As palladium is added to the Ag−Cd alloy,a decreases more rapidly than it increases with cadmium. The rate of decrease becomes less rapid when palladium is present in excess of cadmium.
