Abstract
The change of the vibrational entropy at high temperature due to the disordering of an ordered alloy has been calculated for the linear chain and the square lattice within a harmonic model of nearest-neighbour interactions. For the two-dimensional lattice a step-wise numerical procedure was used. The change in vibrational entropy turned out to be of a similar magnitude to the change in configurational entropy.Keywords
