... In addition to the 3-phase coexistence regions, there are regions of Fig. 3 that show the coexistence of two different phases. The phase rule dictates two degrees of freedom for 2-phase equilibrium (F = 1 − 2 + 3 = 2). After specifying the temperature, this leaves a single degree of freedom. Thus, t ...
