Calorimetric studies and thermodynamic calculations of the Ag-Mg system

The experimentally determined integral enthalpy of mixing of liquid Ag-Mg alloys has been presented. Three separate measurements have been made at 991, 1141, and 1272 K with the use of an MHTC 96 Line Evo line drop calorimeter. The values of integral molar mixing enthalpy are characterized by negative deviations from the ideal solutions in the entire concentration range. Based on the obtained calorimetric results and other thermodynamic data available in the literature, the Ag-Mg system has been re-optimized. Additionally, the mechanical properties of the Ag-Mg intermetallic phases have been calculated based on the ab initio calculations. (c) 2021 Published by Elsevier B.V.

Automated summary

The experimentally determined integral enthalpy of mixing of liquid Ag-Mg alloys showed negative deviations from ideal solutions throughout the concentration range. The Ag-Mg system was re-optimized based on calorimetric results and other thermodynamic data available in the literature, while the mechanical properties of Ag-Mg intermetallic phases were calculated using ab initio calculations.
