situ X-ray diffraction experiments were performed on six samples of the ternary Au-Ag-Pd alloys (with A1 structure) having different compositions using a Cu-target. The integrated intensity data obtained in the temperature range of 373-1200 K was utilized to determine the lattice parameters and the thermal parameters like Einstein's temperatures (Theta(E)), the mean-square amplitudes (u(2)(T)) and the coefficients of thermal expansion with a high accuracy. The lattice parameter showed a small negative deviation from the Vegard's rule. It is also found that the mean-square amplitudes are independent of the static displacements. The mean-square amplitudes of vibration and the linear thermal expansion follow the classical Gruneisen relationship in these alloys. (c) 2006 Elsevier B.V. All rights reserved.
