“…Therefore, theoretical approaches serve as an efficient instrument for investigations in this area. One of them is the square-well (SW) model, which is actively applied to liquid metals and their alloys [21][22][23][24][25][26][27][28][29].…”

The recently developed by us semi-analytical representation of the mean spherical approximation in conjunction with the linear trajectory approximation is applied to the quantitative study of self-diffusivities in liquid Cu, Ag and Au at different temperatures. The square-well model is employed for the description of the interatomic pair interactions in metals under study. It is found that our theoretical results are in good agreement with available experimental and computer-simulation data and can be considered as a prediction when such data are absent.

“…[1], we expanded our SW-MSA approach to binary systems. Here, the binary liquid metal alloy is repre-sented as an SW mixture and the formalism under question is applied to calculate the structure of the equiatomic Na-K alloy at T =373 K. Previously, descriptions of binary liquid metal alloys within the SW model [7][8][9][10] and the SW model with a repulsive SW barrier [11,12] have been performed in the framework of the random phase approximation (RPA) [13,14]:…”

Abstract:The procedure suggested previously for the description of the square-well (SW) fluid within the framework of the mean spherical approximation is applied to calculate the structure factors of pure Na, pure K, and 0.5Na-0.5K alloy in liquid state. It is shown that our variations of the SW depth and SW width enable us to achieve a good agreement between calculated and experimental structure factors. The procedure under consideration gives more accurate results than the random phase approximation for the same values of the SW parameters.PACS (
