General notes: •A general rule is that single phase regions are always separated from each other by a two phase region that consist of the two single phases that it separates. •The solvus line is analgous to the solubility limit line in the sugar-water system. The solubility of Ag in Cu is limited at room temperature and.
19 Oct 2015 We have already seen the 'official' definition of a phase: Physically distinct, chemically homogenous and mechanically separable region of a system. . phase separation. Isomorphous with ordering. Complete Solubility in both liquid & solid states. Limited Solubility in both liquid & solid states. Eutectic.
Eutectic Phase diagram. ?In the eutectic system between two metals A and B, two solid solutions, one rich in A (?) and another rich in B (?) form. ?In addition to liquidus and solidus lines there are two more lines on A and B rich ends which define the solubility limits B in. A and A in B respectively. These are called solvus
A eutectic system from the Greek "??" (eu = easy) and "?????" (teksis = melting) describes a homogeneous solid mix of atomic and/or chemical species, forming a joint super-lattice, by striking a unique atomic percentage ratio between the components — as each pure component has its own distinct bulk lattice arrangement.
A two component system is the simplest of multicomponent systems. A condensed phase rule is the one used to represent the phase diagram of a condensed system, either liquid or solid. In such a case, for two or more components, the phase diagram becomes multidimensional. Look at, F = C – P + 2, for one phase, 2 – 1 +
Eutectic Systems. • The simplest kind of system with two solid phases is called a eutectic system. • A eutectic system contains two solid phases at low temperature. These phases may have different crystal structures, or the same crystal structure with different lattice parameters. • Examples: – Pb (FCC) and Sn (tetragonal)

reach full equilibrium, the solute in the solid phases must stay completely uniform throughout the cooling. However, in most systems, if the system is not cooled quickly, the phase diagram will give fairly accurate results. In addition, near the eutectic, the results become even closer to the phase diagram as the liquid solidifies
