Li0.5Na0.5, Li0.5K0.5, Li0.5Rb0.5 and Li0.5Cs0.5 to second order in local model potential is discussed in terms of real-space sum of Born von Karman central force constants. The local field correlation functions due to Hartree (H), Ichimaru-Utsumi (IU) and Sarkar et al. (S) are used to investigate influence of the screening effects on the aforesaid properties. Results for the lattice constants i.e.С11, С12, С44, С12 – С44, С12/С44 and bulk modulus Å obtained using the Hartree (H) local field correction function has higher values in comparison with the results obtained for the same properties using Ichimaru-Utsumi (IU) and Sarkar et al. (S) local field correction functions. The results for the Shear modulus (С′), deviation from Cauchy’s relation, Poisson’s ratio σ, Young modulus Y, propagation velocity of elastic waves, phonon dispel-rsion curves and degree of anisotropy A are highly appreciable for the four lithium alloys.
