Lattice dynamical calculations are performed on Ta-W alloys with bee structure in various concentrations. We assume ion-ion interaction through the improved third-neighbor Clark-Gazis-Wallis (CGW) model. The theory has been applied to compute the dispersion curves, frequency spectra and lattice specific heat of the studied alloys. The obtained results are in good agreement with the available experimental ones. (c) 2007 Elsevier B.V. All rights reserved.
