The serial sectioning method has been used to measure the solute diffusivities of copper in praseodymium. In the bcc phase the diffusivity of copper can be expressed by D=5.7×10-2 exp(-17 800/RT) cm 2/sec, and in the double-hcp phase by D=8.4×10-2 exp(-18 100/RT) cm2/sec. It is most likely that copper diffuses in praseodymium by means of the combined substitutional-interstitial mechanism, similar to the other noble-metal solutes. Comparison of the present results with the previously measured diffusivities of zinc indicates that the solute diffusivities increase with decreasing solute valence.
