Abstract
Phonon dispersion curves for fcc Cu-25% Zn alloy were calculated using deLauney angular force model, the analysis being limited to the secon d neighbour interactions only. In the present calculations the elastic constants of Cu and Zn in fcc and hcp phases, respectively, were used to evaluate the force constants of the alloy system. Satisfactory agr eement between theory and experiment is obtained.
