Thermodynamic descriptions of the Cu-Zn system

摘要

Cu-Zn is an important binary alloy system. In the interested temperature range from 300 to 1500 K, there are eight phases, liquid, Cu, β, β', γ,δ, ∈, and Zn phases. The thermodynamic descriptions of the Cu-Zn system are reassessed using the CALPHAD method. A new description of liquid phase and simplified description of body-centered cubic (bcc) phase are proposed. Good agreement has been found among the calculated thermodynamic properties, phase diagram, and the experimental information.
