COST 507 - Repositório Aberto da Universidade do Porto

Introduction
It is the aim of this study to determine experimentally thermodynamic properties of
liquid and solid ternary aluminium and magnesium alloys. The results contribute to
understand their thermodynamics and make it feasible with available literature data to
evaluate or reevaluate the corresponding phase equilibria. The enthalpy of mixing of
liquid Al-Cu-Mg, Al-Mg-Zn, Cu-Mg-Y, Cu-Mg-Si, Al-Cu-Zr and Al-Cu-Li alloys has
been determined calorimetrically. The enthalpy of formation at room temperature of
ternary intermetallic compounds in the system Al-Fe-Si have been deteimined
calorimetrically. All investigations are performed in collaboration with other partners
within COST 507-2 [Al-Cu-Mg, Effenberg (D 12), Spencer (D3); Al-Mg-Zn, Effenberg
(D12), Lukas (D4); Cu-Mg-Y, Ipser (A2), Spencer (D3); Cu-Mg-Si, Ipser (A2),
Spencer (D3); Al-Cu-Zr, Hämäläinen (SF1); Al-Cu-Li, Hämäläinen (SF1); Al-Mg-Si,
Lukas (D4), Kolby (NI); Al-Fe-Si, Rogl (Al)]. The COST 507-2 action has given the
opportunity to carry out this work in good collaboration and continous discussion with
the european partners. The results of the different systems are presented in detail as
publications.
