Two of the binaries making up this
ternary phase diagram have a eutectic
point. The third shows complete
solid solubility. There is a eutectic valley
linking the two eutectic points.

This ternary phase diagram has a
ternary eutectic point. This is the
lowest melting point in the system where
L → α + β + γ.

Each of the sides of the ternary are
binary phase diagrams containing
binary eutectics.
