摘要：
Fragments of phase diagrams Al-Cu-Zn-Mg and Al-Cu-Zn-Mg-Fe-Si-(Mn) in a temperature range (%) 4–6 Cu, 2–4 Zn, 0.5–2.0 Mg, 1.5–2.0 Fe, and 1.5–5.0 Si are constructed and the composition of the solid solution for a series of alloys of the Al-Cu-Zn-Mg-Fe-Si-(Mn) system at temperatures near the solidus is calculated by the results of thermodynamic calculations using the ThermoCalc software package. The thermodynamic calculations are verified by electron probe microanalysis. This verification shows the satisfactory convergence of the calculated and experimental data. It is revealed that, with the ratio of iron and silicon concentrations Fe/Si = 0.5 for alloys of the Al-Cu-Zn-Mg-Fe-Si-(Mn) system, it is possible to obtain a maximally doped solid solution.
