Eutectic system. A phase diagram for a fictitious binary chemical mixture (with the two components denoted by A and B) used to depict the eutectic composition, temperature, and point. (L denotes the liquid state.)

Curves representing the Fusion curve (liquid/solid barrier, also known as freezing/melting), the Vaporization curve (liquid/vapor barrier, also known as evaporation/condensation), and the Sublimation curve (solid/vapor barrier)) can be seen in the diagram.

Conversely, when a well-mixed, eutectic alloy melts, it does so at a single, sharp temperature. The various phase transformations that occur during the solidification of a particular alloy composition can be understood by drawing a vertical line from the liquid phase to the solid phase on the phase diagram for that alloy. Some uses include:

Updated September 28, 2015. Definition: For a given substance, it is possible to make a phase diagram which outlines the changes in phase (see image to the right). Generally temperature is along the horizontal axis and pressure is along the vertical axis, although three-dimensional phase diagrams can also account for a volume axis.

In the Al-Au phase diagram, for example, it can be seen that only two of the phases melt congruently, AuAl 2 and Au 2 Al, while the rest peritectically decompose. Eutectic calculation. The composition and temperature of a eutectic can be calculated from enthalpy and entropy of fusion of each components.

The coordinates defining a eutectic point on a phase diagram are the eutectic percentage ratio (on the atomic/molecular ratio axis of the diagram) and the eutectic temperature (on the temperature axis of the diagram).
