In the paper are presented the results of thermodynamic analysis of Cu-Al-Zn
ternary system, which belongs to a group of copper-based shape memory
materials. General solution model was used for calculation of thermodynamic
properties in the temperature interval from 1373 to 2173 K, in sections from
Cu, Al and Zn corner, respectively, with following ratios of 1:3, 1:1 and
3:1. Also, on the basis of the obtained results, ternary interaction
parameters were determined using Mathematical Modeling System (MLAB).
