摘要：

The enthalpy of mixing of the ternary Cu -Sn-Zn system was measured using a Calvet-type calorimeter. The investigations were carried out along the three cross sections Cu: Sn = 1: 2, 1: 1, and 2: 1. Zn was added in the concentration range between 0 and 50 at.%. The calorimetric results were compared with EMF data investigated in an earlier work by Peng and Mikula [1]. The results of the calorimetric measurements show very good agreement in the copper-rich region, compared with the EMF measurements, but in the Cu: Sn = 1: 2 cross section the results do not fit perfectly. The difference between both measuring methods was at the most ΔH = 300 J/mol at the cross section Cu: Sn = 1: 1 and ΔH = 150 J/mol at the Cu: Sn = 2: 1 cross section. © 2006 Carl Hanser Verlag, München.
