Abstract
In the present reevaluation of the Cu-Zn system, the ordering in the β phase is described using a two sublattice model, whereas four sublattices are used to model theγ phase. A self-consistent set of coefficients has been obtained, allowing both the equilibrium phase diagram and the thermodynamic properties to be calculated in close agreement with experimental observations.
