Abstract

The thin layer sectioning technique has been used to measure the self-diffusion and solute diffusion coefficients of lanthanum, holmium and indium in body-centred cubic praseodymium. The diffusivities can be expressed as: Self-diffusion of Pr D = 8.7 × 10⁻² exp (−29400/RT) cm²/sec. Solute diffusion of La D = 1.8 × 10⁻² exp (−25700/RT) cm²/sec. Solute diffusion of Ho D = 9.5 × 10⁻³ exp (−26300/RT) cm²/sec. Solute diffusion of In D = 9.6 × 10⁻² exp (−28900/RT) cm²/sec. The relatively low activation energy and high self-diffusion coefficients in praseodymium were interpreted as indicating that this metal should be classified among the anomalous b.c.c. metals.
