Thermodynamic assessments of the Cu-Sn-Zn and Cu-Pb-Zn systems are presente
d. For this work the evaluations of the binary Cu-Zn, Cu-Pb, Sn-Zn and Pb-Z
n subsystems have been taken from the SGTE database [86Ans], for the Cu-Sn
system the data [96Shi] were used. The results of phase equilibrium calcula
tions in the ternary systems are shown in appropriate diagrams and tables a
nd compared with published experimental data.
