Abstract
The general linear response expressions for isothermal matter transport simplify for the random alloy model with the vacancy mechanism because the jump rates are independent of the local configuration of atoms on the lattice. It is shown that in consequence there are n exact relations between the non-equilibrium thermodynamic phenomenological coefficients for isothermal transport in a random alloy of n atomic components in addition to the Onsager reciprocal relations. These new relations are satisfied by earlier approximate theories. They are advantageous in Monte Carlo simulations of the model.
