Silver - Gold - Copper

Introduction

This important ternary system, acting as the basic phase diagram for an understanding of gold dental alloys, has been studied for the past 75 years. A detailed assessment of the literature has been made with respect to the liquidus and solidus surfaces, the solvus surface arising from the solid-state miscibility gap in the Ag-Cu system, and the ternary equilibria at low temperatures arising from the ordered phases in the Au-Cu system.
