Electron microscopy has a lot to offer materials scientists in helping them to understand the dependence of mechanical and electrochemical properties on the microstructures resulting from phase transformations in dental alloys. A coherent phase diagram gives us effective information as an aid to developing improved dental alloys. This brief article describes the process of construction of a coherent phase diagram for the Aux−(Ag0.24Cu0.76)1−x section of the gold-copper-silver ternary system, which is the essential system of dental gold alloys, using conventional transmission electron microscopy coupled with selected area electron diffraction.
