N2 - The article studies the elastic properties of anisotropy and interatomic anharmonicity in a two-component Cu3Au alloy with positional order-disorder within the temperature interval of 4.2 K and 300 K. It provides calculations on velocities of purely transverse and longitudinal elastic waves, elastic moduli (Young’s, shear, adiabatic bulk moduli) and Poisson’s ratios based on the stiffness constants cij(T) of the crystal. Sound velocity values were employed for determining the temperature changes of Grüneisen parameter along the crystallographic directions [100], [110] and [111].
