- The well-known model potential is used to investigate the longitudinal and transverse phonon dispersion curves for six Ni-based binary amorphous alloys, viz. Ni$\text{}_{31}$Dy$\text{}_{69}$, Ni$\text{}_{33}$Y$\text{}_{67}$, Ni$\text{}_{36}$Zr$\text{}_{64}$, Ni$\text{}_{50}$Zr$\text{}_{50}$, Ni$\text{}_{60}$ Nb$\text{}_{40}$, and Ni$\text{}_{81}$B$\text{}_{19}$. The thermodynamic and elastic properties are also computed from the elastic limits of the phonon dispersion curves. The theoretical approach given by Hubbard-Beeby is used in the present study to compute the phonon dispersion curves. Five local field correction functions proposed by Hartree, Taylor, Ichimaru-Utsumi, Farid et al. and Sarkar et al. are employed to see the effect of exchange and correlation in the aforesaid properties.
