The sum-rule relation among phenomenological transport coefficients and its consequences in the analysis of collective diffusion problems†
Abstract
In this paper, we discuss the sum-rule that relates the phenomenological coefficients in the multicomponent random alloy system in the case where the isolated vacancy mechanism is operating. We present applications of this sum-rule to intrinsic diffusion in multicomponent alloys, intrinsic diffusion in mixed alkali halides and demixing of multicomponent transition metal
