Popis:	The short-range-order structure of complex eutectic In-Sb-Sn, In-Sb, and Al-Sb-Bi melts is examined. The investigations are carried out on a high-temperature x-ray diffractometer. The curves of intensity of coherent x-ray scattering are used to plot the radial atom distribution functions (RADF). The RADF are analyzed for various different models of the structure of the fluids under investigation. It is established that the most acceptable model for the structure of In-Sb-Sn melts is the complex “quasieutectic” distribution corresponding to atom coordination in fused InSb and in fluid In and Sb. In a eutectic alloy of the Th-Sb system there are microinhomogeneous regions enriched with InSb atom complexes and with pure antimony in the total fusion region. A doped type of structure is characteristic of the Al-Sb-Bi melt. As the temperature rises the melts under investigation have a tendency to form a homogeneous solution.
