Abstract: The results of calculations of structure and some surface properties such as, isothermal compressibility, surface tension and viscosity for liquid 3d transition metals, Ti, Ni and V, near melting temperatures are presented. We used the parameters of the Wills-Harrison (WH) approximation in conjunction with the Bretonnet-Silbert (BS) local model pseudopotential, which is suggested separate description of the s- and d—electron states are calculated using Dubinin procedure [1]. Isothermal compressibility and surface tension properties of Ti, Ni and V are calculated using extended Mayer’s empirical formula in terms of hard sphere diameter and packing fraction which calculated using Waseca’s formula [2]. We have obtained in very good agreement near melting point with available experimental data.
