TLDR
In this paper, partial heat of mixing was measured at 725 K for liquid Bi-Sn alloys using a liquid metal solution calorimeter and the experimental data were analyzed using the subregular model and the modified quasichemical model.Abstract:
Partial heats of mixing have been measured at 725 K for liquid Bi-Sn alloys using a liquid metal solution calorimeter. Integral heats of mixing were calculated and were found to be endothermic. The experimental data are analyzed using the subregular model and the modified quasichemical model.read more

Thermodynamic assessments of the Sn-In and Sn-Bi binary systems
TL;DR: In this paper, a thermodynamic evaluation of the Sn-ln and Sn-Bi system has been made by using thermodynamic models for the Gibbs energy of the individual phases, and an optimized set of thermodynamic parameters was obtained taking into consideration relevant experimental information.

Atomic-Scale Surface Demixing in a Eutectic Liquid BiSn Alloy
Oleg Shpyrko,Alexei Grigoriev,Reinhard Streitel,Diego Pontoni,Peter S. Pershan,Moshe Deutsch,Ben Ocko,Mati Meron,Binhua Lin +8 more
TL;DR: Resonant x-ray reflectivity of the surface of the liquid phase of the Bi(43)Sn(57) eutectic alloy reveals atomic-scale demixing extending over three near- surface atomic layers, revealing a near-surface domination of the attractive Bi-Sn interaction over the entropy.

Marian Kucharski,Przemysław Fima +1 more
TL;DR: In this article, the sessile drop method has been used to measure density and surface tension for pure Ag, Bi, Sn, and their mixtures, and a relatively good agreement is observed.

A “sub-regular” solution model and its application to some binary alloy systems
TL;DR: In this paper, the authors examined the thermodynamic properties of binary solutions whose excess free energy of solution is given by ΔF = A 1 x 2 y + A 2 xy 2 + RT (x ln x + y ln y) where x and y are the atomic fractions; the model may be termed a sub-regular solution.
