Thermodynamics of Ordering-Disordering Transformation in Cu-Zn Alloy System

Abstract

Abstract: The α and β phases in Cu-Zn alloy system were regarded as regular solutions at elevated temperature, the results calculated from the experimental data have showed that the value of the interaction parameter of components Cu and Zn in the α phase ECuZnα varied obviously with decreasing component Zn. Substituting the function relation between ECuZnα and XZn obtained through curve-fitting into expression of free-energy variation of the system, the calculated martensitic transformation temperature Ms was in good agreement with experimental curve, so as to have more comprehensive information for fully making use of binary Cu-base functional materials.
