| The
liquidus lines on a phase diagram is the locus of all system states that
represent the boundary between a single liquid phase and the two phase
(liquid + solid) zones on the diagram. For the copper-silver binary phase
diagram shown a liquidus line exists between the liquid phase and (a
+L), and also between the
liquid phase and (b +
L).
These states represent the conditions for the first appearance of solidification as a material of given composition is coled in equilibrium (or the last states at which solid can exist as the material is heated in equilibrium). |
