Xiamen Univ, Dept Mat Sci & Engn, Xiamen 361005, Peoples R China 电子邮件地址: [email protected] thermodynamic database on the phase equilibria of the copper base alloys, including Cu-X binary system and Cu-Fe, Cu-Ni, Cu-Cr base ternary systems has been developed by the Calculation of Phase Diagrams (CALPHAD) method. The thermodynamic parameters describing Gibbs energies of the different phases have been evaluated by optimizing experimental data of phase equilibria and thermodynamic properties. The present thermodynamic database can provide much information such as stable and metastable phase equilibria, phase fraction, liquidus projection and various thermodynamic quantities and so on, which is expected to play an important role in the design of copper base alloys.

Univ Sofia, Fac Chem, Sofia 1164, Bulgaria 电子邮件地址: [email protected] ternary system of Cu-Ni-Zn has been thermodynamically analyzed based on extensive experimental information and reasonable thermodynamic modeling work by using the CALPHAD approach. A self-consistent set of thermodynamic parameters has been obtained, and the experimentally determined phase equilibria in the whole composition range except for the Zn-rich portion have been critically reproduced. The thermodynamic description established in this work can be used in predicting the phase relationships and thermodynamic properties in the Cu-Ni-Zn system. (c) 2004 Elsevier Ltd. All rights reserved
