Anisotropy of Self-Diffusion in Alpha Uranium

Abstract

Self-diffusion along the three principal crystallographic directions of alpha uranium has been measured on mosaic structured single crystals by the tracer-sectioning method. The diffusion coefficients at 625.5°C are D[100]=D[001]=1.95×10−13 cm2/sec,D[010]⩽10−14 cm2/sec. It appears that the mosaic structure has not affected the diffusion significantly.
