FEC: Pxy (Phase) Diagrams - University of Pittsburgh Definition: Tie lines are the name given to lines that bridge the "coexistence space" in a phase diagram. In the example above the lens-shaped region between the line and the curve is a "no mans land" that separates the vapor phase compositions from the liquid phase compositions.

Equilibrium Diagrams - Christian Brothers University An xy diagram like this may be constructed from a Txy diagram by picking a temperature, reading the corresponding y and x and plotting them against each other.
