Self-Diffusion of Silver in Silver—Palladium Alloys

Abstract
The self‐diffusion of silver has been studied in alloys containing 0.00, 1.49, 3.69, 9.87, and 21.84 atom percent palladium at four temperatures: 715.4, 799.4, 861.8, and 942.0°C. The rate decreases with increasing palladium atom fraction according to the relation: DAg=0.270e—8.20Xe—43, 700/RT. An alternative expression is DAg=0.270e—17.75T m/T. Within experimental error, the activation energy is independent of palladium content. The rate of self‐diffusion of silver is related to the solidus line of the silver‐palladium phase diagram, and a simple corresponding states explanation is given.
