The
two component (C
= 2) Copper
- Nickel system will be used to illustrate application of the Gibbs
phase rule to binary alloys.
· Points (a) and (b) are in single phase regions of the two component system. C = 2, P = 1, p = Constant, Fp = [C - P + 1]p= 2 Both composition (% Ni) and temperature (T) are independent variables. · For (c) in the two-phase zone : C = 2, P = 2, p = Constant, giving: Fp = 1 · If either T or the Composition is specified, the other is fixed. |
