Equilibrium phase diagram of the Ag–Au–Pb ternary system

Abstract

The phase diagram of the ternary system Ag–Au–Pb has been established using differential thermal analysis and X-ray powder diffraction analysis. Four vertical sections were studied: X Pb = 0.40, X Au/ X Pb = 1/3, X Ag/ X Au = 4/1 and X Ag/ X Au = 1/1. Two ternary transitory peritectics and one ternary eutectic were characterized. A schematic representation of the ternary equilibria is given.
