摘要
The Ag-Pb-Sn ternary system is an important material system for both electronic packaging and thermoelectric applications. However, there is no experimental phase equilibria information of the ternary system. Ag-Pb-Sn alloys are prepared and their phase equilibria at various temperatures were determined. The focus was on the 500, 350, and 200 degrees C isothermal sections. Additional information was also obtained for 400, and 300 degrees C. Several samples were studied by DSC studies. No ternary compounds were found in the ternary system. The Ag-Sn binary compounds, Ag3Sn(epsilon) and Ag4Sn(zeta) at 350 degrees C and Ag4Sn(zeta) at 500 degrees C, exhibit very small Pb solubility. The thermodynamic assessment of the ternary Ag-Pb-Sn system was carried out using the above mentioned exper-imental data.
