Abstract
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) cm2/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.This publication has 15 references indexed in Scilit:
