The structures of a liquid eutectic alloy and one corresponding to the near-equatomic concentration in the phase diagram are investigated at different temperatures. The structure factors and pair correlation functions have been analyzed and interpreted. The temperature dependences of main structure parameters determined from these functions allowed us to suppose that the atomic distribution in both alloys is characterized by a tendency to the interaction of like-kind atoms. In addition, the structure data and the results on the density and surface tension are analyzed as well.
