Abstract

The solute diffusivities of gold and silver have been measured in f.c.c. γ‐and b.c.c. δ‐cerium using the serial sectioning method. The results can be expressed as follows: In f.c.c. γ‐cerium: D^Au = 4.4 × 10⁻³ exp (−14900/RT) cm²/s, D^Ag= 2.5 × 10⁻² exp (− 21100/RT) cm²/s; in b.c.c. δ‐cerium: D^Au = 9.5 × 10⁻² exp (− 20500/RT) cm²/s, D^Ag = 1.2 × × 10⁻¹ exp (− 22200/RT) cm²/s. Comparison with self‐diffusion in cerium indicates that the solute diffusion of the noble metals takes place via a different mechanism, most likely the dissociative diffusion mechanism.
