The purpose of this work is to achieve thermodynamic assessment of the Cu–Pb–Zn system. The latter was earlier assessed by [10] but that description could not be adopted directly due to the earlier fixed strategy [11], [12] of applying the simple substitutional solution model for the gamma phase (see Chapter 2). Also the binary data used for the …
