Abstract
A comparison is made between the free energies of activation for boundary migration during normal grain growth, grain-boundary self-diffusion, and liquid self-diffusion. The equality of these, within the accuracy of experiment and analysis, supports the assumption of identical elementary processes in the three cases. A detailed discussion is given regarding the various constants used in the equations from which the free energies of activation of the above-mentioned processes are derived.Keywords
