Abstract

A careful investigation of the Sn-Ag-Cu phase diagram near the ternary eutectic composition was undertaken using annealed alloys and differential scanning calorimetry to settle some uncertainties in the eutectic composition. The eutectic composition was found to be 3.5 wt pct Ag, 0.9 wt pct Cu, and the balance Sn. The published eutectic temperature, 217 °C, was confirmed. A value of 217.2 °C was obtained in the present research.
