On the temperature dependence of the enthalpies of mixing in liquid binary (Ag, Cu, Ni)–Sn alloys

Density studies of liquid alloys SnAg and SnZn with near eutectic compositions

“…It means that the interaction between similar atoms predominates in the melts. This can be confirmed by the phase diagram of eutectic type and the positive heat of mixing for dilute liquid Sn\Ag alloys [14]. The investigated melts remain a microheterogeneous system at elevated temperatures and do not reach the state of true solution even at 1270 K. The absence of anomalies, hysteresis and changes of slope at d(t) curves prove the idea.…”

The Effect of Sb Addition on Sn-Based Alloys for High-Temperature Lead-Free Solders: an Investigation of the Ag-Sb-Sn System

“…Direct reaction calorimetry has been employed by different scientists to measure the mixing enthalpy for the Ag-Sn system: Wittig and Gehring 13 in the composition range 0.072 < x Sn < 0.931 at 975°C, Castanet 14 in the range 0.05 < x Sn < 0.95 at 1000°C, and Rakotomavo 15 in the range 0.02 < x Sn < 0.934 at 1100°C. Recently, Flandorfer 16 carried out calorimetric measurements at five temperatures in the interval of 500°C to 1250°C, mainly in the Sn-rich side, and at 1250°C for the Ag-rich side. The data published up to 1973 have been assessed by Hultgren.…”

Calorimetric studies and thermodynamic properties of liquid Ag–Ca alloys

“…The drop calorimetric technique is well established [15,16] and in the case of two component (Ag-Ca system) the measured enthalpy is the integrated heat flow at constant pressure and follows this equations:…”
