If Ω < 0 and the number of A—B bonds is greater than this, the solution is said to contain short-range order (SRO). The degree of ordering can be quantified by defining a SRO parameter s such that s= PAB − PAB (random) PAB (max) − PAB (random) where PAB(max) and PAB(random) refer to the maximum number of bonds possible and the number of bonds for a random solution, respectively. 19 illustrates the difference between random and short-range ordered solutions. 5, PAB ~ 100, S = 0. 32. In solutions with compositions that are close to a simple ratio of A: B atoms another type of order can be found as shown schematically in Fig.

27 (a) Alloy X0 has a free energy G1 as a mixture of α1 + β1. (b) At equilibrium, alloy X0 has a minimum free energy Ge when it is a mixture of α e + βe. 31 Thermodynamics and Phase Diagrams α and β phases until the compositions αe and βe are reached, Fig. 27b. The free energy of the system Ge is now a minimum and there is no desire for further change. Consequently the system is in equilibrium and αe and βe are the equilibrium compositions of the α and β phases. This result is quite general and applies to any alloy with an overall composition between αe and βe: only the relative amounts of the two phases change, as given by the lever rule.

Is the change in energy when 1 mol of B with the α-structure dissolves in A to make a dilute solution. Therefore Q is just the enthalpy change, or heat absorbed, when 1 mol of B with the β-structure dissolves in A to make a dilute solution. ΔHB is the difference in entropy between β-B and α-B and is approximately independent of temperature. Therefore the solubility of B in α increases exponentially with temperature at a rate determined by Q. It is interesting to note that, except at absolute zero, X Be can never be equal to zero, that is, no two components are ever completely insoluble in each other.
