Self-diffusion in Au along isolated dislocations

The complete solution of dislocation-pipe diffusion is applied to self-diffusion data of gold from the literature. The diffusivities reported herein are based on a fitted dislocation density of 10⁹-10¹⁰ lines/cm². The resulting diffusivities are D=0.07exp[-(1.73 eV)kT] for the bulk and Dₚ=2×10^-3exp[-(1.24 eV)kT] for the dislocation pipes. The calculated radius of the pipes is a=(1.5±1.0)×10^-6 cm.
