Lattice and Grain Boundary Self-Diffusion in Silver
Abstract
The lattice and grain boundary self-diffusion coefficients of high purity silver have been measured over extended temperature ranges. It has been found that the lattice diffusion coefficients are described by the equation, DL=0.895 exp(-49500/RT) cm2sec-1 and are independent of the thermal history of the crystals within wide limits. The absolute grain boundary diffusion coefficients fit the equation, DB=0.03 exp(-20,200/RT) cm2 sec-1 and are independent of the grain size of the specimens.
