Abstract
Nachtrieb's Tm/T law for diffusion in solids under pressure is derived under the assumption that the melting curve of the solid can be described by Simon's melting equation. A necessary condition for the Tm/T law to hold is that the activation energy ΔH and volume ΔV obey an equation ΔH = AcΔV, where A and c are the Simon constants. This equation is substantiated by a comparison with the available experimental data.Keywords
