Cu Zn Phase Diagram

The phase diagram shows in pressuretemperature space the lines of equilibrium or phase boundaries between the three phases of solid liquid and gas. Congruent transformation is one where there is no change in composition like allotropic transformations eg a fe to g fe or melting transitions in pure solids.
