Self-Diffusion in Copper

Abstract

The self-diffusion coefficient of copper has been determined by tracer techniques through the use of a precision grinder and a precision lathe. The temperature dependence over the range 685-1062\ifmmode^\circ\else\textdegree\fi{}C is given by $D=0.468\mathrm{exp}(\ensuremath{-}\frac{47140}{\mathrm{RT}})$ ${\mathrm{cm}}^{2}$/sec.
