Structure of the ternary gallium-indium-tin eutectic system in the liquid state

An x-ray study has been made of the short-range structure of the ternary gallium-indium-tin eutectic system in the liquid state at T = 288, 308, and 368 °K. Intensity curves were compared with the diffraction reflections of the components. The radial distribution of atoms was calculated. This distribution is interpreted for model quasieutectic and statistical distributions of the scattering atoms. Near the melting point, the distribution of In, Ga, and Sn atoms in the alloy consisting of 62% Ga, 25% In, and 13% Sn (by weight) is quasieutectic, and a transition occurs to a homogeneous physical solution as the temperature is increased.Translated from Izvestiya VUZ.
