Abstract

The serial sectioning method was used to study self-diffusion in cerium metal. In the fcc γ phase, D=0.6e-36600RT cm2 sec-1, and in the bcc δ phase, D=1.2×10-2e-21500RT cm2 sec-1. The diffusion parameters in the fcc structure are compatible with a normal vacancy mechanism. The high diffusivities and low activation energy in the bcc phase are characteristic of diffusion behavior in anomalous bcc metals. Similarities with self-diffusion in bcc ε-plutonium are stressed.
