Thermodynamic evaluations for highstrength, hotstrength and wrought aluminium alloys D3 Tatjana Jantzen, Suzana G Fries, Iñaki Hurtado, Michel H. G. Jacobs and Philip J. Spencer Lehrstuhl fur Theoretische Hüttenkunde, RWTH Aachen, Kopernukusstr.16, D52074 Aachen, Germany Abstract In this work, thermodynamic evaluations of the binary system CuSi and the ternary systems AlCuMg, AlCuSi, AlCuZn, CuMgSi, CuMgY and Cu MgNi are presented. The results of the calculations are compared with published experimental data and with experimental data which have become available during the progress of the COST Action 507. 1 Introduction Highstrength, hotstrength and wrought aluminium alloys are of considerable technological importance. For their design and development a knowledge of the phase constitution, which influences the mechanical and physical properties of the alloys and thus their suitability for particular applications, is essential. LTH has been concerned with the thermodynamic evaluation of systems based on AlCuMgSiZn (Ni,Y),which is one of the key systems in COST 507 Round 2. The binary subsystems have already been evaluated in the first round of COST 507. The thermodynamic assessment of the ternary systems, on which calculations in more complex systems are based, has been the major aim of the work in the second round. Particular attention has been given to the modelling of phases such as the Laves and the Τ phase, since it is essential that the models used are compatible for the description of the extensions of the phases into all the different subsystems in which they appear. 2 Data Assessment A significant number of all the binary and ternary subsystems of the AlCu MgSiZn system, on which calculations in more complex systems are based, have already been evaluated in the first round of the COST507 Project. 2.1 The Cu-Si system In view of experimental data and the necessity to describe ternary systems into which several of the binary phases extend, the CuSi system was reevaluated. 73
